I have a need for small resistance measurement and would prefer to stay with AD2 .
A simple circuit addition with just a few components, BNC adapters and Kelvin clips seems simple enough .Controlled current source at approximately 100 MA and 4 point measurement The LM317 can be replaced by alternate devices , designs are common .
Calibration and display in ohm unit could be done in the logger function with measurement of the actual controlled output current .
It would be nice if the voltmeter function had the capability to adjust the units displayed and capability to do the required basic math .
Can anyone validate this approach as compatible with the AD2?
