Extech PQ3450 3-Phase Power Analyzer/Data Logger

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

Meter came very fast with everything but the software. This is not an issue as the software is available as a download (search for Extech DL160 software download). I unzipped and installed the software however I did not install the drivers. Tech support was great and told me I had not installed the drivers. Once installed I got the User Interface. It is basic but works fine. I was able to set the time on the meter, no problem. I have set the meter up to run overnight so I can see how well it works. For the price, I am pleased with the quality as I expected it to be flimsy but it is fine for my purposes. I think it is well thought out with magnetic that allow you to stick the meter and leads on metal panel enclosures.

perfect !

Software terrible. Switches itself off randomly

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.
