5.2.  AC VOLTAGE MEASUREMENT 

 

 

CAUTION 

 

The maximum input for AC voltage is 600V. Do not attempt to measure 
higher voltages to avoid electrical shocks or damages to the instrument. 

 

 

Fig. 3: Using the instrument for AC Voltage measurement 

 
1. Switch on 

V Hz%

 position 

2.  Insert the test leads into the jacks, the red plug into 

mAµAV

Hz%

 jack and 

black plug into 

COM

 jack  

3.  Connect the test leads to the circuit under test (see Fig. 3). The voltage value is 

displayed 

4.  If the message "

O

.

L

" is displayed the higher range is reached 

5.  For use of HOLD, RANGE, MAX MIN functions please refer to § 4.2
