Review: Extech DL160 Dual Input True RMS Great product! - I want to say first, the people that complained about this meter being made of cheap plastic, need to compare it to most testing instruments. The quality of the plastic used is of the same quality of any other. The only thing they could have done better is to install a silicon type cover for shock protection. The fact is, you should take care of any kind of quality instrument. Wake up and stop griping. You only make yourself sound ignorant. With that said, the reason I purchased this instrument, was to show my electrical provider that it was there incoming power to my home that was causing the issue with power surges, not my end. There linemen came out and did a quick check of the pole and a load test at my meter base and it showed good. After receiving the Extech DL160, I took my readings at the input lines of my main disconnect directly after my meter base. It showed no issue across L1 and L2, but when tested from the neutral to L1 and L2 it showed an issue. Large 30 plus volt spikes. Narrowed it down to the neutral as expected. I was able to get the printouts from the meter to the power companies’s engineer, and he set out a crew right away. After some time redoing wire clamps and almost giving up, they found the neutral on the transformer lose. Without this meter, I would probably still be fighting the power company to fix there problem. I don’t know if I’ll ever use this meter again, but it was well worth the money to save my own electronics, etc in my home and the satisfaction of proving to the power company it was there side causing the problem. (-: Lol
Review: Worked great. - The Extech 382100 worked as expected. This datalogger is very easy to use and the logged data is stored nicely as an Excel document on a SD card. This made making graphs and using the data very easy. The only thing I didn't like is the 2 second minimum interval for readings. This isn't fast enough to catch the starting amperage of a motor every time. Otherwise everything worked like a charm, saving us money and time.

## Questions & Answers

**Q: how does it measure current? is there cts'? aslo can it be installed without de-energizing the load?**
A: There are current clamps for every leg as well as gator clip probes for every leg N and ground (I think there is also a current clamp for N but I don't have it in front of me.) There is no problem hooking it all up live as long as you are careful. I've never had a problem.

**Q: Does it comes with wi-fi capabilities for remote data analysis?**
A: No, it does not have that capability.

**Q: will it work with linux?**
A: Hi, thanks for your question, Unfortunately, the software is only available and has been tested for windows 7,8,10, and 11. if you have any questions, feel free to contact our technical support line at 866-477-3687 option 3

**Q: What is the maximum wire diameter the current clamp will fit on?**
A: While I cannot say for sure what the maximum wire size is that the current clamp would fit on, it will certainly fit on any wire sized per NEC to carry the allowable amperage that the DL 160 is max rated to measure. Any larger wire sizes would most likely be in an installation subject to more amps than that max rating, possibly damaging the device(s) if deployed to same. Only exception I can think of is where the allowable amps would be within limits and still encounter a larger than normal but then also a much longer wire would be in use to allow for voltage drop.

### ⭐⭐⭐⭐⭐ Convenient, works great
*by K***R on January 20, 2021*

Bought this along with some Fluke magnetic voltage probes (https://www.amazon.com/gp/product/B016DPE10U/) in order to monitor voltage levels and current usage. Have tested both current and voltage capabilities and both work well and seem accurate. Software feels a bit dated, but is functional. Would recommend.
