## Questions & Answers

**Q: Why is it necessary to clamp a single conductor with a clamp meter to measure current instead of the entire power cable?**
A: A two-prong cable has live and neutral wires; a three-prong adds ground. Current flows oppositely in live and neutral wires, canceling magnetic fields. Clamping both may show zero. For accuracy, clamp each wire separately

**Q: Where is the NCV function implemented on the clamp meter?**
A: The NCV probe of the clamp meter is located at the protruding part of the clamp tip. Simply bring the clamp meter tip close to the object being detected when using the NCV function

**Q: How long does the data hold function last?**
A: The data hold function will last until you press "H" again to exit the data hold mode

**Q: Which hole do the red and black test leads insert into?**
A: The red test lead connects to the INPUT jack, and the black test lead connects to the COM jack

## Customer Reviews

### ⭐⭐⭐⭐⭐ So nice, I bought it twice.
*by I***. on July 26, 2024*

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.

### ⭐⭐⭐⭐⭐ Working Great!
*by W***B on May 17, 2025*

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.

### ⭐⭐⭐⭐ Works great
*by R***N on July 18, 2025*

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.
