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.

1. Set the function switch to the 

 position. 

2. Press the MODE button to indicate Ω on the display.
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

WArnIng:

 To avoid electric shock, never measure continuity on 

circuits or wires that have voltage on them.

1. Set the function switch to the 

 position.

2. Press the MODE button to indicate 

 on the display

3. Touch the test probe tips to the circuit or wire you wish to check. 
4. If the resistance is less than approximately 150Ω, the audible signal will 

sound. If the circuit is open, the display will indicate “OL”.

1. Set the function switch to the 

 position.

2. Press the MODE button to indicate 

 on the display.

3. Touch the  test probes to the diode under test. Forward voltage will 

typically indicate 0.400 to 0.700V. Reverse voltage will indicate “

Ol

”. 

Shorted devices will indicate near 0V and an open device will indicate 

Ol
