#023 - UM34C USB power meter teardown HD

Here is a look at the inner workings of the UM34C USB dongle meter, and of course some testing. The bluetooth function on this is great, and the app works as expected - only annoyance is that when power is lost to the meter you have to disconnect and when saving the logged data, the old file gets overwritten. Nonetheless, it is a great toll for diagnostics, data logging and monitoring on USB charging - quality product from RD tech.
