Anybody know how to make ICL7106 based resistance-meter turn on automaticaly when resistance is connected and go off when resistace is removed. Something like stand-by.
It's auto ranging meter with two ranges: 0-19 Ohm and 20-2000 Ohm.
Measuring current must be lower than 1mA. Right now works fine with 0.1mA.
One of my problems is that I can't make it work without analog common. That's another how-to....
Thanks
