Have used the clamp meter a few times on various vehicles with different faults. Meter works well cannot fault it good battery clear screen easy to use.

Fantastic meter at an affordable price. Purchased for low voltage automotive jobs very versatile bit of kit.
Gary C. (verified owner) –
Found the amp clamp accurate and very easy to use the controls are intuitive and straightforward in operation great value for money.
Riccardo G. (verified owner) –
The current clamp has a small LCD where you can see the evolution of the signal over time. It would be perfect if it were possible to have that data on the USB socket of the instrument so that with external software you could record the evolution of the measured signals.
andrew c. (verified owner) –
Delivered on time got to work with it straight away. Really easy to use and the display is brilliant also has a good battery life between recharges. Highly recommend it.
Bluey (verified owner) –
Clamp on multimeter is well priced and does measure AC as well as DC current which many don’t. Rechargeable as well very happy.

I bought the DMC-100 to measure mainly active and standby currents for PCs HDDs and electric apparatus. For this purpose it fits perfectly and I like it. The problems but minor are ergonomic design on clamp trigger and flashlight button. I would rather the flashlight button move slightly downward to avoid pressing it when pressing the clamp trigger. It also did not come with a case.

A couple of things that cross my mind. I don’t see any way to calibrate zero on the DC clamp. I now have a few of the FNIRSI devices. What they need is one computer app that lets you plug all of them into a computer and view waveforms and chart results.
Bino J. (verified owner) –
Display character size of AC DC clamp readings is found to be a little small so there is difficulty in reading out parameters. Try to make the display character size bigger. Great highly accurate and very useful product. Thank you FNIRSI.

I finally decided to give this tool a shot. Delivery was a bit slow but it did finally arrive. As others mentioned it would have been nice to have a soft protective pouch. I like the needle point test leads. Usage wise it’s great. The display is great I can even read it without glasses. Would I recommend this tool for sure!
Matt (verified owner) –
Display is nice. Good product.
Juan G. (verified owner) –
The meter is good but the leads I think need to be better quality. My leads only lasted a few days.
Peter (verified owner) –
This meter has everything I need in one instrument – NCV clamp temperature continuity even frequency. I find the charting function invaluable especially for thermostat operation. It would have been nice to include a case.
WOJCIECH S. (verified owner) –
I have had several multimeters in my life but this multimeter is in a class of its own. There is no better multimeter. It updates its measurement very quickly and does it very precisely.
Kent H. (verified owner) –
I found the clamp on amp meter to be quite accurate and easy to use especially the display and the battery life. I wish the probes came with alligator clips and the diode test beep to be more distinctive.
Ricardo T. (verified owner) –
Not done discovering all the features but so far I’m really impressed with what I found. Would have given it a perfect score with better documentation.
Oleksandr H. (verified owner) –

I use this clamp meter mainly for automotive diagnostic work it has been very effective in this capacity. I am very pleased with it so far.
Alan F. (verified owner) –
This little multi-meter has all the features and then some of some of the most popular meters but for a quarter if not less of the price! I’m blown away by how great this meter performs. It has all my colleagues genuinely scratching their heads wondering why they spent $400+ on a meter with sometimes less features.

Love the size and functionality for the price. I would love to see more in the literature about its CAT ratings other than printed on the unit. Something put down in black and white would be good and would make it more trusted by professional electricians.
Lucas R. (verified owner) –
For $35 I bought this because why not. I’ve used it on multiple jobs now and so far has been great. Only 4 stars because I don’t know the longevity of the meter yet but so far so good. Did not come with a case so also why it won’t get 5 stars from me. Needs to come with a case.

Ulrich B. (verified owner) –
Easy to handle nice display feature for showing in low resolution the signal.
Alan A. (verified owner) –
I really like this meter. Lots of functionality for a very reasonable price. The ability to graph readings is not something you use every day but has come in handy. Small light and compact with a very nice display. DC current clamp works well. The battery life is good but a non-replaceable battery is limiting. The leads I got are not up to the quality of the rest of the meter and had to be replaced. Overall I really like this instrument and would not hesitate to recommend it.
Meik F. (verified owner) –
The unit is cool to check power in PV strings which is the reason I use it mostly. More options are possible but only one issue is it has only Chinese or English language. I wish German would be available with a firmware update.

I now have the amp clamp and soldering iron both are fantastic bits of kit. Was a bit dubious at first but these are definitely not cheap Chinese rubbish. The prices are really good and certainly worth buying very impressed.

The device functions properly and the shipping was fast. However the packaging unfortunately arrived damaged though the product itself was undamaged. I recommend that the product be placed in a more durable cardboard box prior to dispatch. Card payment was also problematic.

I purchased a meter about 9 months before the second purchase. I am a HVAC tech and had a problem with my regular meter so used this one as a backup. WOW! It does have all the settings as my meter to test capacitors. I ordered the second one for my son as he is in the HVAC industry. Thank you for your products.

Matt F. (verified owner) –
I’m a calibration guy. I was skeptical of this product for the price but out of the box I made a template for it and was ready to test it. This product was well within specified spec and I have been using it daily for odd little jobs around the house and at work.
Herm H. (verified owner) –
I think this is going to become my favorite handheld meter for home work and automotive. Having the ability to measure high current DC amps is the reason I purchased it but it does just about everything I need and being rechargeable is icing on the cake. The accuracy falls short of best in class but definitely qualifies as good enough for most uses. The only real shortcoming is the leads.

I bought the Voltmeter and I was impressed with the unit. I always have used a Fluke industrial voltmeter but it does not have the capability to measure current using the clamp and this voltmeter does which is a big improvement. So far it has worked well and the unit seems solid and well-built and has a carrying pouch. For the price I paid this unit punches well above its weight.
