Q: Low mA draw measurements? How well does this work for measuring mA draw from a device? I'm using it for Arduino-based devices testing low power modes and need to see current draw in the mA ranges (10-80mA). How well does this work in those ranges?

Britespark It only has 2 decimal place resolution, so using Arduino you're almost always seeing a power drain on 0.01A. At this level the timer doesn't seem to trigger, at least mine never does.
