Resistance Measurements
Resistance is a static measurement which means that it must be measured with the power off. It is measured in
Ohms (Ω) and the values can vary greatly from a few milliohms (mΩ) for contact resistance to billions of ohms
for insulators.
TURN OFF POWER AND DISCHARGE ALL CAPACITORS IN THE CIRCUIT TO BE TESTED BEFORE MAKING
IN-CIRCUIT RESISTANCE MEASUREMENTS. ACCURATE MEASUREMENT IS NOT POSSIBLE IF EXTERNAL
NOTE:
The resistance in the test probes can affect accuracy in the 400 range. Short the probes together and
press the "REL" button to subtract test lead resistance from the measurement.
