About this app

E-test is an APP that can view the running status of the energy meter in real time, and records the state of voltage and current power in a curve form.

Ratings and reviews

After getting a USB tester from Amazon awhile back I tried using this app and it wasn't compatible with the current Android OS at the time so it left the BT functionality useless. BUT, that is no longer the case as it's been updated and 100% working now. Thanks for the update!

Works! To the negative comment about it not doing anything you can't see on the device, I say Not True, because the device doesn't graph without the phone app. In my case, I want t know what my welding machine draws while I am welding, and with my eyes looking at the weld while welding, I can't be simultaneously looking at the device, so the retrospective graph is essential to my purpose. Blue tooth connection seems squirrely, but I think the key is to have the app turned on and ready when you plug in/power up the device so they connect during the "welcome" screen time. I could be wrong on that, so, fiddle with it till it works. Also, it seems to (not 100% sure on this yet) disconnect and not automatically reconnect if you walk out of range. Mildly frustrating, but manageable. Finally, scratched my head about why VxA was not equal to watts in AC, like in DC, and finally sorted out that due to shape of sine wave there is a lot of time that the actual voltage is not at full 110 (or 220, or whatever) so, that reflects in actual Watts being always less than V x A. Do your own homework before trusting me on any of this. :) 5 stars. Works and does what I need.

I use eTest on ATorch ammeters, AC, DC and USB on Android devices. The Android version connects to the low energy Bluetooth signal (BLE), so range is limited to no more than 30 feet. I can take screen shots of the graphical display of usage which can be scaled by using your fingers to expand detail by voltage and amps along the side of the graph. I use it in 12v DC applications that are tight in this large scale.
