Arrived as promised. Accuracy is questionable based on other reviews but I haven't tested it against my Fluke. Has an amazing amount of features for the price. Bought this to replace my Mastec which lasted two years with daily use because of the added features like non-contact sensor and temp probe. The lighted display is great, makes it easy to read in low light conditions. Wish it included alligator clips for the probes.ONE MAJOR DRAWBACK:The beep for checking continuity and non- contact sensor are barely audible. Useless If there's any background noise. I may contact the seller to see if this is normal.

Amp meter fails to read below around 2 amps. The voltmeter fails to read AC on auto and so far at all. First time.

The first feature to fail, and the one I most needed, was DC amps. Now AC amps, AC and DC volts are gone,too. On the plus side the flashlight works great!This meter is a complete waste of money...pure junk.

It is amazing, like it.The best clamp-meter under 100 that you may find in the store.Good body quality and accurate measuring.Like it so

Standard meters will only go up to 20A DC. I own a heavy equipment service. We often need to measure current greater than 20A. With standard meters, anything greater than 20A would burn out the fuse. Before meters with self-resetting fuses, it meant throwing the meter away or having to open it up to change the fuse. I don't know how many times my guys have hooked up an ammeter in series with a battery and accidentally turn on the lights or cranked the starter. These clamp meters are surprisingly accurate. Also in the past, I've had problems finding DC clamp ammeters for under $200. This one really is a bargain. I also appreciate the auto-range selection. I've wasted weeks of my life trying to explain to people how to set the range on multimeters.

I have to admit I was skeptical initially buying this meter considering the brand is Mastech and another well priced clamp AMP meter by Klein is similarly priced. The Mastech has so far exceeded all of my expectations. I found the AC AMP reading to be well enough calibrated for my line of work and the DC reading was satisfactory for reading alternators. I really like the probes included, however they could have a less fine point that would allow me to hold the contact better. The sharp point may be beneficial if you plan to stick the probes into a wire or connection. The voltage reading was as accurate as my other meters, but this is the highest quality of the meter I have. The OHM reading was also useful for my vape coils and the onboard OHM reader in my vape reported similar readings within a small margin. Overall great meter for the money.

Giving 2 stars as of now..the unit is DOA after just under 3 months of light use. Amazon support gave me an international number to call MASTECH which is BS. I found NO WARRANTY info at all either on the provided user manual or on MASTECHs website...i did find a USA number in CA to call mastech, where i was given an email address to write to...in other words, right off the bat any kind of warranty is a run around. Will edit this review given any response from Mastech..OK, the seller was very helpful and has responded that they are replacing the unit. New one is in the mail and they provided me a UPS tracking number. This I find to be quite a plus! So hats off to the seller- Measuring InstrumentsSo on another note, out of curiosity, I opened the unit (2 philips screws, one above and one below the battery bank) and see that there are (2) spring contacts that connect the +/- from the battery bank to the pc board of the meter. I put a drop of Deoxit contact cleaner on each and low and behold got the unit working again..albeit briefly, after a few tasks she died again, so there must be some other demons in the electronics.I do work out of an un-airconditioned shop and I live in the deep south w/ high temps and humidity, perhaps this particular meter is not suited for such an environment. Otherwise it seems like a decent meter especially for the $$, will see on the replacement.Another note: I still could not find any warranty info from the manufacturer Mastech. Nada in the provided manual, nada on there website and nada response to email sent directly to them (per phone call to Mastech USA number) so that said, maybe this brand is to be avoided.As for the seller on Amazon, Measuring Instruments, their customer service was top notch, so I give a 3 star rating at the end of the day.....

meter works as advertised; it's not a Fluke, but it does what it is supposed and advertised for. Current measurements are pretty good for what I'm using it for, basic confirmation of current flow and crosscheck with what the motor is supposed to draw, etc.Pretty good meter and I liked the price.

This meter looks nice, however the case is a bit cheap and so are the electronics and firmware. On the 60 Amp DC range it will consistently show 0.2 to 0.5 Amps of offset error with nothing near the meter. There is no way to calibrate the offset error, but even if one could, it drifts too much anyway. The peak minimum and maximum feature is useless, it responds much too slow, if you can’t read the changing values in normal mode the current pulse was too short to register in peak mode. Example, you will not be able to measure the current your car takes to start with this meter.

This is an excellent meter for servicing equipment and general use. Considering how many functions is has, it's an incredible bargain. I compared the current measured by the clamp with my reference Amprobe DLC-100, and they are very close. The non-contact voltage sensor (NCV) is the most sensitive I've seen (almost too sensitive); it sounds the alarm when the meter is within 6" of an energized wire.The box contains:* The meter itself* Test probes* Thermocouple probe* Batteries (3 AAA)* Zippred case large enough for the meter and the probes
