6.5. Resistance Measurement

WARNING: To avoid electric shock, disconnect power to the unit under test

and discharge all capacitors before taking any resistance measurements.

1. Set the function switch to the highest Ω Position.

2. Insert the black test lead banana plug into the negative COM Input Jack;

Insert the red test lead banana plug into the Positive Input Jack.

3. Touch the test probe tips across the circuit or part under test, it is best to

disconnect one side of the part under test so the rest of the circuit will not

interfere with the resistance reading.

4. Read the resistance in the display and then set the function switch to the

lowest Ω Position that is greater than the actual or any anticipated

resistance, the display will indicate the proper decimal point and value.
