Operation

 

AC/DC VOLTAGE MEASUREMENTS   

CAUTION: 

  Do not measure AC/ DC voltages if a motor 

on the circuit is being switched ON or OFF. Large voltage 
surges may occur that can damage the meter. 

1.  Insert the black test lead into the negative COM terminal 

and the red test lead into the positive V terminal. 

2.  Set the function switch to VAC or VDC position. 

3. 

Connect  the  test  leads  in  parallel  to  the  circuit  under 
test.

 

4. 

Read the voltage measurement on the LCD display.
