4.2. Inrush Current Measurements

1.  Set the function switch to the 

600A

 or 

1000A

 position.

2.  Press the 

INRUSH

 button (Enter key for 2 seconds) to indicate “Inrush” 

on the display. Then measurement display “----” .

3.  Clamp the cable to be motor.
4.  Start the motor.
5.  Read the inrush current in the display.

4.3. AC/DC Voltage Measurements
WARNING:

 Risk of Electrocution. The probe tips may not be long enough 

to contact the live parts inside some 240V outlets for appliances because 
the contacts are recessed deep in the outlets. As a result, the reading may 
show 0 volts when the outlet actually has voltage on it. Make sure the 
probe tips are touching the metal contacts inside the outlet before 
assuming that no voltage is present.

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.  Set the function switch to the 

V AC/DC 

position.

2.  Insert the black test lead banana plug into the negative 

COM

 jack. 

Insert the red test lead banana plug into the positive 

V

 jack.

3.  Press the 

MODE

 key to switch AC or DC Voltage functions.

4.  Read the voltage in the display.
