    5.0 out of 5 stars Extech DL160 Dual Input True RMS Great product!
    Reviewed in the United States on June 3, 2023
    Style: Dual InputVerified Purchase
    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

    Manual was out of date and didn't apply correctly to the device. I had to find the manual on line and download it. Product tech support is marginal at best. On the only time it was to be used our technician could not get the analyzer to properly log transient capture even with simulated voltage dips. This should be a simple set up but it did not work. I'd return it but we've had it too long since the purchase date. It's just an expensive voltage/amperage tester.

    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

    4.0 out of 5 stars Works as advertised. Needs a comptuer for setup...
    Reviewed in the United States on November 15, 2016
    Style: Dual InputVerified Purchase
    Works at advertised. The basic idea is to connect the Extech to a computer, via USB, and set it up with the Extech software. This allows you to specify the sample time, etc. Once set, you can disconnect the Extech and, in our case, take it to the location in question. Connect to the power to monitor and push the start button. Our setup would capture till memory on the Extech was full and then stop. You can setup it up to overwrite the oldest. A pleasant surprise was the battery life! We have run the unit for 6+ days on the original AA's and they are still showing 3/4 life. We also noticed that you need to pay attention to the probes - they are marked for channel 1 and 2. We had them swapped and saw a 1.4 volt inaccuracy. After swapping them back, all was good. Note that 1 second samples with 2 probes works out to about a day and a half monitoring. If you need more, get the next model up with more memory.
    I wish there was a way to "reset" the unit without connecting to a computer, a small thing but would be handy the way we use it.

    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.
