I needed a device that showed low power consumption. Most of the work I do is industrial repair of highly automated PLC controlled equipment. I need something that can measure the small currents used in digital control circuits in today's devices. I've only used it a few times so far and it works as expected. but. The lower range (10 mV/A) is not zero. The minimum value I can reset it to is 3.1 to 3.6 mV. If you take a reading and subtract 3.3mV zero from the reading, it's accurate. The device wasn't expensive, so I can take it. It works well (and correctly) in the swing range (1mV/A). Note. I use this with a Fluke 117 meter.
