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.

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.

CONTINUITY CHECK

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.  Insert the black lead banana plug into the negative 

(-)

 jack 

(COM)

and the red test lead banana plug into the positive 

(+)

 jack 

(Ω)

.

3.  Press the         button until the     symbol appears in the display.

4.  Touch the test probe tips to the circuit or wire you wish to check. 

5.  If the resistance is less than approximately 

100Ω

, the audible 

signal will sound. The display will also show the actual resistance.
