Resistance Measurements
WARNING: To avoid electric shock, disconnect power
to the unit under test and discharge all capacitors
before taking any resistance measurements. Remove
the batteries and unplug the line cords.
Model 20250-50:
1. Set the rotary function switch to the highest
Ω
position.
2. Insert the black test lead banana plug into the negative
COM jack and insert the red test lead banana plug into
the positive
Ω
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 rotary
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.
Model 20250-51:
1. Set the rotary function switch to the
Ω
position.
2. Insert the black test lead banana plug into the negative
COM jack and the red test lead banana plug into the
positive
Ω
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. The display will
indicate the proper decimal point, value, and symbol.
