I sometimes buy inexpensive test equipment, perform a quick review and then post the results on my w3afc.com web page. I do this for the benefit of the HAM Radio operators who want to repair their own equipment, but who are on a fixed income. I''ll post a full review with photos there in a couple weeks. This review is for the typical homeowner or DIY hobbyist who wants an inexpensive but full-featured meter. For comparison, I tested this meter against a much more expensive Amprobe AM-570.

PROS:

- The dual, plastic coated magnet on the back is very useful. I can stick it to the face of one of my vintage HAM radios while I''m doing some testing and it will stay there.
- It has a large, easy-to-read display.
- DC and AC RMS readings are well within the claimed specifications. Spot-on, in fact.
- Resistance, DC current, and Diode forward voltage readings are accurate. I haven''t tested the Duty Cycle or Temperature functions.
- The build quality is above average for a meter in this price point.
- According to AstroAI, this meter can read voltages as high as 1,000VDC (CAT II) and 750VAC, but they don''t emphasize that. I have yet to use it to measure the 900VDC plate voltage on one of my Swan 700CX tube transceivers, because I want to get some use out of the meter first before I risk blowing it up. Plus, I plan to use this primarily for testing circuits in cars, and solid-state HAM radios. I had a UEI 384 that claimed a max DC voltage rating of 1000 volts, but when I tested the Swan plate voltage (at rest, no modulation) the UEI blew up - literally. I found another one online for 20 bucks used, and tried it again. THAT meter also blew up. So I tend to take the voltage ratings on these cheap meters with several grains of salt.
- The manufacturer claims that this meter will read capacitance up to 600 micro-farads (uF). But the one I''m testing has measured up to 2200uF with good accuracy. Perhaps they meant 600uF within the stated accuracy.

NOTE: I''VE CORRECTED MY RATING based on the fact that this meter is rated at 60,000 uF. The largest value I have right now if 20,000, and this meter reads it with the same approximate accuracy as my much more expensive Amprobe AM-570, and my CEM DT-9935 LCR.

CONS:

- That magnet that I mentioned above can pick up nuts, staples, pins, and other stuff, so it''s a bit of a double-edge sword.
- The claimed frequency counter upper limit of 60MHz is actually 16MHz. Apparently, when engineering told marketing that it would read to 16MHz, marketing thought they said 60. And, the voltage required to obtain a reading is fairly high, almost 5V P-P. The Amprobe AM-570 on the other hand reads accurately up to 43MHz, and it only needs a little over 1V P-P for a good reading. Of course, it costs about $110, or almost 4 times as much as this AstroAI WH5000A. Note: I just checked my Amprobe manual, and it claims to read to 60 MHz also. I have a feeling that this is just a theoretical figure, based on the fact that these are 6000-count (5999, really) meters.
- The transistor hFE (current gain) test function is at only 1 volts, and at a very low current of around 1mA, so it reads about half of the gain of a device under typical conditions. And for some reason, the multi-function test adapter is arranged C-B-E instead of B-C-E, making testing TO-220 devices a hassle. So, DON''T buy this as a transistor tester.

As I said, I''ll post a complete review on my web page eventually. For a hobbyist, or DIY''er, this is good, and the price can''t be beat. For HAM Radio work I would spend a little more. BTW, I don''t find the beeping to be THAT annoying.

NOTE: The DC voltages were supplied by a Tektronix Calibration Fixture. The AC voltage was from a regulated AC supply, set at 115.00 VAC. I tested the AC separately instead of alongside the Amprobe meter because the AC supply doesn''t have BNC connectors like my Tek DC supply. With the probes detached, the AstroAI picked up a small amount of AC, most likely from my fluorescent lighting.

NOTE 2: In the photo of the meter testing something on the underside of a radio, the meter is measuring the frequency 14.175MHz from the signal unit of a Kenwood TS-930S HAM transceiver. The meter is connected to the board near the output terminal. It reads the signal, but the gain from the board (carrier level) has to be set at 10 to obtain a reading. By comparison, the Amprobe can read the signal at a carrier level of 4, and a very old Beckman Industrial DM27XT can get a reading with the carrier control set at 2.

In the two new photos of the meters measuring the value of a capacitor, the AstroAI and the Amprobe are measuring the same 2200uF, 35V electrolytic capacitor.

The manufacturer contacted me regarding my 3-star rating. Compared to other meters in the $30-$50 range, this would be 4 stars, perhaps even 5. However, I would only give the Amprobe AM-570 4 stars, so for the sake of consistency, I give this 3 stars.

By the way, I have the thermocouple connected right now, measuring the ambient temperature right here in my HAM shack. It''s fluctuating between 71 and 73 degrees as the heat cycles on and off, which is about right. I put the end under my tongue for a few minutes, and it leveled off at 95F. So it''s not lab grade, but it''s not bad.

EDIT: AstroAI customer service is good, they refunded me and allowed me to keep the meter. please read on for an evaluation. I am going to give this a tentative 3 stars, and I''ll explain that below.

It beeps VERY loud(a very strong 2khz square wave beep) for every little thing, changing modes, a button press, it''s really annoying. There''s no option to disable it that I can find. I opened the unit and removed the piezo unit so it will never beep again. Other residents complained from hearing it while in my indoor workshop on a separate floor. The beep issue loses a star.

Now that I have gotten past all of that beeping nonsense... It does suck a little that I had to remove the piezo unit, since I like watching what I''m doing for certain precision continuity tests. (SELLER take note: As we spoke in our email, I don''t believe anyone has a use for the beeping beyond continuity testing for this unit)

The delta function works as expected, but only on a linear basis, obviously, so keep that in mind while testing.
The back-light stays on for about 12 seconds. I might rewire mind to stay on while the unit is on, and I may convert the unit to rechargeable Li-Ion too.

The included probes aren''t THAT great. I''m not sure what it is lately, but every new probe I have bought from discount retailers has a different plating than my older probes, and it makes contact difficult. I had to scratch-in my probes to get a few impedance measurements, or give them some high pressure to get a reading. I replaced them for further testing with high-quality cat IV 1000V probes.

The magnet is just two rare earth magnets in the strap part, and one steel washer on the body (inside) of the DMM. It''s ok, not terribly strong. I would absolutely NOT use that to hold the unit over a running engine or something equally critical; it does not take much of a yank to pull it down on accident. For a stable environment, on an iron object, it may work well. Be smart about that one, or it could swing into a bad spot, or cause a reach/grab panic when it falls, indirectly causing loss/injury. Paranoid? I prefer to be vigilant about possible problems, that''s all.
However, the slot on the DMM could be used with a ty-wrap or other reliable strapping for a more secure hold for sure, it''s solid polymer.

This meter seems to be a little less affected by dynamic/static EMF than the other 2017 units I have bought. The lowest range measurements are within the specifications given for the most part. The motherboard of this unit is a general unit, it is not purpose built. The motherboard is the same as a number of other low-cost multimeters, including those with different micro-controllers, USB functionality, and some others. I may modify a handful of the hardware on this unit, just to see if it''s capable of extended operational features.

Capacitance testing is limited, but it works. I would have loved testing around 10-100F for my EDLC''s. Voltage testing is well within spec, current measurement is within spec, impedance seems OK, but the issue persists with the given probes as mentioned above, so some erroneous reporting is present without really forcing good contact.

The NPN/PNP testing module is a pain, the order doesn''t support NPN mosfet IC packages due to the ordering, so I have to bend my terminals around to get a reading, unlike every other DMM I have. It''s annoying, but it works. My other units use a different Vce value too, so that''s something to get used to for bench testing. Also, I will probably lose the testing bud. I don''t think there is a reason to make those units external and removable. One advantage, the bud can be used with diodes, so you aren''t fumbling with test leads to check diode forward voltage.

Frequency test seems to be on target with a square wave generator (tested at 1khz), and reads 2% off target on my power filter, which is properly calibrated to laboratory specifications, at 59.98hz. Not a big deal, just an observation. I think this is still within spec out of the manual.

Auto power off function cannot be disabled without modifying the unit, so what''s the point of having an LCD symbol? This lead me to believe it could be disabled.

Now for the most important part of all, the safety stuff.
The fuses are proper for the given category of application. I do not have a means to hi-pot/arc test the probes here. DMM case is well isolated and insulated. I am comfortable using this on single phase 220 and 110, and just about anything lower voltage. I want to test the output for the active testing, but I am OK not measuring that. Remember, this is only rated to CAT I @600 V, and CAT II @ 300V. I would suggest anyone who isn''t familiar with this, read Flukes safety release PDF on line categories. It could save your life.

It''s OK as a quick test measure device, for the price, it''s not terrible, it''s reasonably accurate, but the features need work, big time. Consider the beeping, too.

Well obviously this is not a high end meter at this low price but with a wide range of functionality, 6000 count display and claimed TRMS its still of interest and very useable. Its big in size with a sort of odd looking blue-ish backlight but a large easy enough to read display. Accuracy and update speed are surprisingly good as is repeatability, as always long range reliability remains to be seen. The magnet hanger is a nice idea but needs a stronger magnet to be really useful. Leads are suprisingly decent after a good cleaning of the tips with fine steel wool and alcohol. Overall accuracy seems very good and the meter has an acceptable not overly loud but audible continuity tester and the meter zero''s out well when leads are shorted. Both ranges are fused with both the 9v battery and the two small ceramic appearing fuses accessable after removing the battery cover. None of the screws in the case have metal inserts, but again this is a budget meter so not an issue at this price. My worst complaint is though im glad it has a backlight its got a slightly odd look - like many it only stays on a few seconds and when you turn it on theres a weird slightly washed out effect on the numbers, dont get me wrong the display is easily readable just not as vivid and crisp in appearance as others - someone else may not care about or even notice this, and as budget meter its not really an issue. Im not really unhappy as I knew what to expect going in, the meter works well with a lot of functionality offered - but one should keep in mind you can get the Fluke 101 pocket meter now for under $50 and even though not as much functionality its got the robust and proven Fluke reliability thats been shown in tests on YT - just depends on what youre after in a meter - overall this meter is not a bad buy but check other options in this price range, there are some good values elsewhere as well. One might ask why I didnt buy the Fluke 101, a fair question. One answer is this meter offers a lot more functionality, two I already have a fluke 17B+ but the main reason was simple curiosity based on reviews. I saw decent reviews and a large display with lots of functionality for a low price and im a bit of a meter collector so I bit - this is the kind of meter you dont mind taking with in a toolbox or tossed in the truck etc., get yourself a cheap carry bag to fit online and youre good to go for very little $$. - if someone "borrows" it not much to lose vs. a Fluke or similar priced meter. Even with the little things I mentioned its a good buy and you could do worse for the money, but again lots to see in this price range so have a look but be careful theres lots of junk out there so read and watch any available YT video reviews on any meters youre considering.

I ordered this for one reason only. To trace what appeared to be a parasitic drain in my Jeep. I felt pretty stupid when I was done.

The meter worked to perfection. I set it to DC voltage (Capital V with a line next to it with three dots under that) so I could measure millivolts (mV). Prior to testing I made sure I had not started the Jeep, opened doors or in any way done anything that might cause even a temporary power drain. I opened the fuse box in the engine compartment and started touching the meter probes to the tiny metal spots exposed on top of each fuse. Some showed 0.0 mV. Some showed a value around 0.3 mV and then went down to 0.0 mV. Normal so far. Woah! This one is sticking at 10.5 mV. Not good. What is that fuse for? Power outlet. Uh oh. My Jeep has two power outlets. One switched and the other unswitched or on all the time even if the key is off. It’s winter. I have a heated pad on the drivers seat. I thought I had it in the switched outlet. Had it in the unswitched. Unplugged the heat pad. Test the fuse again. 0.0 mV. Stupid is is stupid does.
This meter has some good weight to it so it doesn’t feel cheap. I’m not sure about the magnets. They are two disk shaped magnets woven inside the short strap that hangs from the top of the meter. There is an indentation in the back of the meter made specifically for the magnets to stick to, but they still tend to slide around. If you use them to hang the meter from something metal they will do the job, but if you should bump the meter or yank the leads then the meter is coming off and going to the ground. Being unsteady on my feet and too often losing my balance I’m a prime candidate for this scenario. The magnetic strap is a nice thought, but I find it to kind of be in the way and it tends to interfere with the weak grip of my hands making it more likely that I will drop the unit. I don’t need it. I’ll probably just remove the strap with the magnets.

I didn’t try the kick stand as I was outside working on the Jeep. Not good in that scenario. It might be good if your working at a table or workbench. I would probably reach for it with my unsteady hands and knock it over.

The leads seem to be good quality and are plenty flexible. They are three feet long not counting the banana plugs or the probes. I would like to have seen a pair of alligator clips included in the package.

I tried the thermocouple by touching it to the electric stove for a couple of seconds and the temperature shot straight up. I did it quick so as not to damage it but then read that it can go up to two thousand degrees. I’m not sure what I might use this feature for. Maybe check my soldering iron to see if it’s really as hot as it says it is.

I like that it takes – and comes with – a standard nine volt lithium battery. No hunting for some strange battery you have to order online. I avoid anything that uses alkaline button batteries.

Some say there is storage in back for the probes. The only storage I found was for the battery and fuses for which the cover is screwed closed. Matters not as I’m ordering a case.

The back light for the screen is very bright, but it only stays on for ten seconds and there is no way to increase that or make it stay on permanently. If you’re working in a dimly lit area it could be a problem. I was outside at dusk when I was testing my fuses and I had to keep pressing the light button so I could clearly see the screen. I’m sure this is to keep it from sucking up the battery, but it can be inconvenient. At least the screen is huge with huge digits.

It would be nice if this came with a case. I would have paid a little more to get that and the above mentioned alligator clips. I’m ordering some clips and a case separately.

I’m older and my eyesight is not what it once was so I would like the instructions – which are very basic – to have been printed with larger text. I downloaded the online manual.
https://images-na.ssl-images-amazon.com/images/I/812ObWAnIxL.pdf It’s got the exact same information, but it is readable.

A couple of times during my testing the meter blurted out a series of quick beeps. I didn’t have the leads touching anything at that moment but I was testing fuse after fuse touching them with the probes so what was up? I pressed the light button and the screen didn’t show anything unusual. Nothing in the manual mentions these beeps. However, per the manual the meter automatically shuts off in fifteen minutes if it detects no activity. Perhaps the beeps were a warning telling me the meter is about to power down. I turned the meter on and started a stop watch. At fourteen minutes I got the beeps. A minute later it powered down. Theory proven. Unfortunately, touching the leads to things apparently does not count as activity. Activity is apparently defined by pressing a button or turning the dial. So, if you hear those beeps you need to reach over and tap the ‘light’ button or else the meter will shut down and you will have to turn it back on. No doubt this is another battery saving feature, but if you’re doing a lot of the same type of testing without having to change anything on the meter then you are required to keep letting the meter know you are still working. I understand the purpose, but I don’t like the feature. It should recognize that the leads are being used.

I understand they use to come in yellow. Mine is red. I like red.

I would like to have the option of keeping the LCD screen back light on or at least on longer and I would like to have the option of disabling the fifteen minute auto off feature. For the low price it sure feels high quality. Overall I am very satisfied with this multimeter.

Small update:
I removed that strap with the magnets. I found that every time I set it down on a metal surface it was sticking. The first time it happened I nearly lost my grip on the meter. I got tired of picking the meter up and having to give it an extra little yank to pull the magnets free. Although they stick to the back of the meter, when I set the meter down on the hood or the bumper they got a better grip on those or what ever other metal surface I had set the meter down on. Better to remove them completely than to risk getting the meter yanked out of my weak feeble old hands. No doubt the magnets in the strap is a useful feature for some people, but for me it turned out to be more of a handicap and introduced the risk of me picking up the meter and dropping it. I don''t think I would ever stick those magnets to something and let the meter dangle precariously by the strap anyway. The magnets were a nice thought, but they don''t work for me.

Update: I''ve had it nearly a year. I''ve found more use for this meter than I ever thought I would. It has functioned flawlessly except that it has developed some kind of loose connection for the LCD screen. I have to push down on the top center of the screen for the information on the screen to show up. To fix this I had to wedge a little sliver of something under the edge of the casing at the top of the screen. Other than that I am very happy with this meter. I don''t know why it developed this issue as it has never been dropped or banged on anything. I''m still happy enough that I still rate four stars.

Once I received this I read the instructions before even turning it on. After I connected the red wire to imput and the black to com. Then turned it on to resistance and touched both red and black leads together, and it read .04 and when moving the wires around it goes to. 05. So that tells me the wires are bad. After hooking up my old multimeter wires it then read .03, and it didn''t change after moving the wires around. It seems to be a decent meter other than crappie wires.

UPDATE... After my initial review, customer service contacted me and wanted to send me a replacement test leads. They work much better and I am very happy with the response with AstroAI.

Not sure why this meter is rated so highly, other than is "looks" like a good value. The positives, has a big screen and backlight option.
Observations:
1. The tips of the leads are far too short to fit into a regular outlet. I though, well I''ll just use my test old leads, which leads to my second observation.
2. The leads are special, current standard leads will not fit due to the black and red lead diameters being different
3. If you don''t know your electrical symbols you will be forced to look them up, why not just have DCV and ACV labeled, it would not take up any more room around the dial.
4. The text and symbols on the printed instructions are very small, I could not even read them with reading glasses on.
5. The first time I tried to measure DC Amps (with the correct setting) the meter stopped working. I was measuring an old battery with a listed 7.0 AH, well below the 10A maximum.
6. Minor, the rubber surround is unlike any other it does not go around the top.
7. Minor, the meter has very light weight/cheep feel
8. It comes in a cardboard box, instead of a zip pouch or case.

Very disappointed that Amazon granted this product "Amazon''s Choice" status.

Incredible. Right out of the box had a ton of issues:

-- backlight only stays on for 10 seconds or so. infuriating. you''re always having to long-press to get it to stay on for any significant length of time.
-- didn''t measure voltage correctly (or at all)
-- diode setting didn''t work at all
-- almost impossible to open stand without damaging device
-- test lead covers are nearly impossible to get off and easy to damage actual leads by trying to remove covers w/ pliers.

flabberghasted that this was recommended. will certainly make me think twice when seeing amazon''s choice products in the future.

I do not like to leave negative reviews, but felt the need to write about this awful product in an attempt to save other customers from being misled about this item. Here is a summary of why I would AVOID this at all costs: The test leads DO NOT WORK at all. This is mentioned in several places on the internet. You MUST replace them. With decent leads from a fluke or DiLog, the meter does actually work. However - even with decent leads the readings are inaccurate. The back-light switches off after 30 seconds and there is no way to over-ride this. This makes is useless as you have to keep going to the meter to switch it on. The ''adapter'' for testing transistors etc is cheap and nasty. The sockets are so tight you cannot actually get a component in. Useless. The build quality feels very cheap and I would be surprised if this lasted any length of time. The kickstand is hard to open and paper thin. The unit is very bulky for what it is. On the plus side - the red is a nice colour! To summarise - this seems like a fantastic value item on paper - but it is in reality very cheap and very nasty. I have nothing against low cost good value items, and have several cheap meters that do a great job. This product has been hyped on the internet (are the ''best value multimeter''s'' pages you find where this is listed as number 1 actually independent and unbiased?) I found it to be completely unusable and returned it as not fit for purpose. My recommendation is to ignore the 5 star reviews (I am not sure what they are comparing this to but I have an old £10 meter from about 20 years ago that is 3 times as good as the AstroAI and has decent leads) If you want a budget meter look elsewhere. There are several other budget meters that offer accurate measurements and come with leads that work. If you want the best, get a fluke. If you want a really decent meter at a fantastic price - check out the DiLog products. They are a UK company (formerly based in Wales, but I think have moved the head office to Manchester) with products equivalent in quality to Flukes but around half the price. Their customer service I have found to be very responsive and helpful too. Give them a try and support a UK business!

I bought this as a spare, in case I need a simple multimeter for testing or small projects. This multimeter is obviously not a High-end meter but with a wide range of functionality - it is a great choice for its price when it comes to doing Home electrical, Automotive (12vdc) electrical troubleshooting, Heater/Boilers troubleshooting (24vac), Solar installation testing and troubleshooting (12-48vdc), etc. · It has a nice and useful magnetic hanger. · It has a stand for the multimeter to stay up (unfortunately, it is a bit fragile - open it carefully). · Easy to use, compact, and has easy to read display. This is not the meter I would use to make sensitive electronics, fine adjustments of electrical components, computer work, etc. - for computer work/repairing motherboards/sensitive components - I prefer something more expensive, multifunctional and more accurate. 👉 This meter is also nice because if you accidentally damage it or lose it you are not out much money. ✔ Pros: + Build Quality is OK for the price + Big screen + Backlit + Easy to Use + Affordable ✖ Cons: - Fragile kickstand - ’’Glow’’ effect on the right side of the screen - Rigid switch - Beep, Beeep, BEEP (lots of beeping) The reason I am giving this multimeter 4 stars is because the issues with this meter are really not issues to me, or rather: they are not so significant for my purposes - because the situations that cause those issues can usually be worked around and 99% of the things, I use this meter for work accurately and rapidly. Overall, I think this is okay for a lot of home uses especially for the price. I would probably buy a much better meter if I needed something for a professional job. ↘ ↘ ↘ If you found this review helpful, please show some love by clicking the "Helpful" button below.

I bought this meter as I had two problems to solve. My knowledge of electronics is very basic so I wanted something that was straightforward to use with some auto settings. The first problem was a portable air conditioner that had stopped working which turned out to be a failed capacitor (after watching youtube clips on how to test for this). The second was to try to identify why the battery on my Ford Transit was draining when not being used. Again I had to use the internet to find out how to test the battery. I was very pleased how easy the meter was to use and read the various measurements. Can''t wait for something else to go wrong to use this to diagnose the problem.

To be honest I''ve struggled a bit in what to write in this review. I have owned and used this multimeter since purchase what must be a be a year ago, although I do have several, it has performed effortlessly when used. So yes if you want a good multimeter that works and your working on a nice tidy bench then add this to the potential list. Although NO for the RRP of £32.99, YES for discounted sales of under £25..............but............. On a personal note I have I would NOT EVER again purchase one! Here''s why. The screen is big but try to use it in anything but perfect light conditions and you can''t read the didgits. Also just as annoyingly - unless you have the screen perfectly facing towards you again you will only see blurry numbers or a reflection of the room - and yes I do have good vision (although everything else though is barely useable!!). You can avoid this by simply pressing the screen illumination button for a couple of second and have the whole screen light up in a cold blue and be seen perfectly from anywhere you place it. But no matter what you do, read the manual a million times, the light will not stay on but for a few seconds - never long enough - half way through taking whatever readings you were the screed goes dark and the light has to be turned back on which like I said involves depressing and holding a small button - which cannot be done when balanced on a shelf, in a hole, hanging from a nail or anywhere else you would have the multimeter in the real world. The second operationl joy of this machine is the painful, loud and extremely annoying squawk it will admit after a few minutes, its the warning sound to tell you you have left your unit on. Normally this would not be a problem, tap your ends together , take a reading, press a button would, on any other unit, reset this toe curling squawking - NO not this unit it will continiue ever few seconds untill you take the unit and turn the operations wheel, the main wheel, to the off position. Which will lose your setting etc. For exmple to use the continuety beep, you have to turn the selector wheel to the section that includes this, but its not the option that will be the one it automatically goes to, you have to press a seperate key untill you reach that setting. Then when you are twisted into some wierd position so you can check some elctronics behind a wall it will also start sqwarking to remmind you to turn it off. You have to crawl out of your hole to turn the machine off and on because you only want positive continuity sounds not be second guessing yourself because of some needless alarm - after doing this twice i go back to the ten quid unit that does not do it.

One of the things I instantly loved about this meter is the large back lit screen, that is view-able from nearly any angle. The magnet hanger is an absoloute joy. But silly as it sounds the cream in the cake for me is the continuity test, the beeper is fast. Really fast. I purchased this as my old multi-meter (A Fluke 87) got full of water (at work) whilst I was on holiday and as I''m leaving my current career soon didn''t want to spend the godless price of a new fluke. This meter is a twentieth of the price, and true the build quality isn''t as good as the Fluke, but it seems to do everything else just as good. Don''t think about it get one!!!
