Extech 382100 1200A 3-Phase Power Analyzer/Datalogger

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

I have used this for a few different reasons.One is to hook up and watch for inconsistancy of power for my customers.The other is the inconsistancy of my power bill at my own home.I don't know....... about the "accuracy" of those smart meters and how I could possibly be using the power I have to have an $850 power bill... I know how power works and what takes what to operate. so.....I've been using it recently to see the exact power consumption at what times to compare to the monopolizing corporate company that supplies my home..... this is the unit to use.Who knows... this unit may get me on 20/20

Item arrived with internal damage to LCD display. However, even if it was perfect it would still be garbage. It has the build quality and same cheap type of plastic used in a $5.00 meter, not a $2000 one. All parts are of the lowest quality construction possible. Everything about it feels cheap and unsafe. Manufactured with the high standards one would expect from the 12 year old sweatshop worker in TAIWAN who assembled this back alley abortion of a meter. I can not speak to the functionality of the unit because the display was broken. High price does not mean high quality, at least not in this case. Step it up Extech! - quit cutting corners and make products worthy of the ridiculous prices you charge!

It works with Windows 7 Home Prem with latest updates. The data logger software is supplied with Silicon Lab's UART driver version 5.4.24 in the installer. If they had added the version 5.4.29, it would have been windows 7 certified.This is what I did to make sure it works:I downloaded the Extech software ver. 1.2 from their website and only installed the data logger software. When prompted to install the drivers, I canceled that part of the installation. I then downloaded the drivers from SIL's website. As of this review, currently at 6.7, which claims windows 8.1 compatibility. I found the drivers here: www. silabs. com /products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx (remove the spaces)As for the product itself, all I can say at this time is that it seems to work when I tested the voltage probes. The alligator clips are wide though the tips are a bit too tall to fit into tight spaces. Current clamp testing will have to wait until I buy some wire to step up the current to measure below 10A as another reviewer suggested. It is not water resistant (or water proof) even though it has covers for all the openings because the channel covers on the bottom do not stay in place when not in use. Not mentioned anywhere I've seen is that it has a pair of magnets on the back to mount the logger during use.I do wish they had cut out spaces in the mid level foam to hold the test probes instead of having them loose in the bottom foam. I'll probably need cut spaces of my own in the foam.

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.

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.

Unfortunately this product doesn’t record minimum, maximum, average, and instantaneous readings for every interval. All you get is an instantaneous reading at each interval. This makes it pretty useless. You can’t do a 30 day load study due to no averaging and you’re very limited on troubleshooting power problems due to no triggers or minimum and maximums being recorded during the intervals

I use this device to monitor stray AC current to my meter stations for the gas company that i work for. I will say the program is easy to use, works on all Operating systems with out any issues.Programming was easy and simple. with plenty of parts for both Voltage and Amps..Easy, simple, long battery life. no issues
