Selecting Functions  

Select measurement as shown in the diagram on the back of the meter. 

 

V dc and V ac Functions  

Rotate the rotary selector to the V position. V dc is the default function. The 
dc annunciator 

F

 appears on the display. Press the SELECT button 

momentarily to select V ac. The ac annunciator 

B

 appears on the display. 

Resistance, Continuity, Diode, and Capacitance 
Functions  

 

Turn the rotary switch to the 

/

R

/

G

/

 position. Resistance is the 

default function. 

1.  Turn off power to the circuit being measured. Never measure resistance 

across a voltage source or on a powered circuit. 

2.   Discharge any capacitors that may influence the reading. 
3.   Connect the test probes across the resistance. 
4.   Read the display. If OL appears on the highest range, the resistance is 

too large to be measured or the circuit is an open circuit.
