Wanted : Ohm Meter schematics.
« on: June 29, 2013, 12:46:59 PM »
Looking to build a few devices that have a built-in ohm meter, but am struggling to find a decent schematic for the 0 - 3 ohm range. Any suggestions ?

Thanks

Moggy

Had seen that one, but wasnt 100% sure it would measure in the range I am after. Would need tweaking.

Thanks for the reply.

I wonder if you can adjust accuracy with the 50 ohm pot.
Maybe the 9v batt for the meter could be eliminated by using a display like the 1S-6S and maybe also eliminate the 9v battery for the LM317 by using the mod battery.
