Hello everyone,
I am attempting to make my own low ohm meter in the range of 0 100 Ohms.
I have based my circuit on the design shown in the link below:
http://www.electronics-diy.com/electronic_schematic.php?id=951
The circuit kind of works ok, however I would like more stability in the readings I get. I measured across a 2.2ohm resistor and was getting fluctuating readings between 1.8ohm and 3ohms on my panel readout display.
When I use my digital multi-meter in replace of the panel meter I get a stable reading close to 2.2ohms.
Is there anything I can do to make this circuit more stable?
Do I need a different panel meter voltage readout display?
I would be very grateful if anyone can help me with this project.
Regards,
Jamie.
