You could buy a Fluke 116 or use a low burden voltage converter.I would like to measure a low voltage DC current that is expected to be in the .25 to 2 microampere range. I have a Fluke 115; is there an inexpensive solution?
Thanks.
It's hard to say, because we don't see range switch position. But I suspect 1mV/1μA so we have 18.1μASo, in the attached photo, how much current is the watch drawing?
Excellent news.I bought the μCurrent from adafruit. It works well; I was trying to build a timer circuit that would respond to a button push, but draw no current when idle, and minimal current when active. As it turns out, the best I could do was a 10nA idle current.
