TCM-300D Smart Clamp Meter

Wanted an extra clamp meter at home which could both AC and DC currents, and ran across this one -- so I bought it. And again because it was that good.The physical construction is good. The blue casing leans towards the purple spectrum, which I don't mind at all. Indeed, I'm trying to justify purchasing a service cart from a particular tool store chain because it's purple -- but I digress. There's no bumper case, but the plastics feel quite solid and details like an actual threaded insert for the battery cover is welcome. Note that the test probes have removable safety covers -- just pull them off if they get in the way.Accuracy on both units were very good as verified against a calibrated Fluke at my work. At low DC voltages, this was off by 0.006V. At 120V AC line voltage, it was off by 0.2V; 0.3V at 240V. Measuring DC amperage on a battery bank via clamp versus the battery controller's own monitor, it was off by 0.1A at around 55A. Overall, for the testing I did, the specs were off by less than half of 1%, with the majority being less than 1/4% off. On a couple occasions, it did auto selected AC current when I was looking for DC. One press of the [SEL] button switched it to the correct mode, however.Additionally, the manual is a full manual (6 languages, 115 pages) and more importantly, it's well written! Besides the aforementioned test probes, a set of temperature probes, a soft carrying case and three Duracell AAA batteries are also included, though you will need to supply your own screwdriver to remove the battery cover. Overall, for it's good construction, very good accuracy, and great value, this gets 5 stars.

The TESMEN TCM-300D Digital Clamp Meter arrived on time and in excellent condition. I'm using it to diagnose a parasitic draw on a car battery, and it’s been easy to use with clear, accurate readings. So far, it’s performing just as I hoped and has been a helpful tool for the job.

This is a great multi meter. I have used it multiple times at work. Accurate temps.The only problem I have had with it is the automatic function. It doesn't seem to work.It is worth the price.

Why did you pick this product vs others?:thought I'd try this meter, works great and had a lot of nice features. would buy again

Great multimeter with lots of features for a great price. Quality feel, easy to navigate functions. Only down side is that you can't change temp function to be F over C. Screens shows both but the dominant reading is C.

Works great!

I am using it at work and the truth is that I am fascinated with this product I recommend it facilitates you a lot for the price excellent decision of vompra

Decent home meter
