Note: 

1)

 

Clamp two lines  of the measured circuit  or more at the same time will  not 

obtain correct measurement results. 

2)

 

To obtain accurate readings, try to enable the measured cable in the middle 

position of the current clamp. 

3)

 

In the maximum capture current mode, the meter only measures current, it 

will not measure voltage and resistance at the same time. 

4.6 Non-contact Voltage Detection (NCV) 

1)

 

Press PMAX/NCV key for 2s, enable NCV function, the meter displays   

 

 
 

 

2)

 

Press NCV key, put the NCV sensor close to the measured cable, the meter 

could detect if the measured cable is >90V AC voltage or not. When the meter 
detects AC voltage, the meter buzzer alarms and the backlight flashes. 

 

 

 

 

 

 

 
Note: 

3)

 

  Even there is no alarm indication, the voltage might still exist. Do not judge if 

there exist voltage or not in the cable relying on non-contact voltage detector. 
The  detection  operation  might  be  affected  by  various  factors  such  as  the 
socket design and insulation thickness types are different and so on. 

4)

 

In NCV detection mode, the meter will not measure the  voltage, resistance 

and current at the same time. 

4.7 AC Current Measurement 

1)

 

Hold the trigger, open the clamp head and clamp one cable of the measured 

circuit.
