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
power leads.
1.
Set the 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.

4. Touch the test probe tips to the diode or semiconductor junction you wish to test. Note
the meter reading.
5. Reverse the probe polarity by switching probe position. Note this reading.
6. The diode or junction can be evaluated as follows:
• If one reading shows a value and the other reading shows OL, the diode is good.
• If both readings show OL, the device is open.
• If both readings are very small or 0, the device is shorted.
NOTE: The value indicated in the display during the diode check is the forward voltage.
