4.4 Preparation before measurement
4.4 .1 Tap the power source button to power on. If the battery 
 voltage is low (about 2.8V), the monitor will display " " 
 symbol, then should charge. Press the power button again 
 to turn it off.
4.4 .2 When the instrument is not measured, the instrument enters 
 the automatic scanning state and the instrument displays 
4. 5 Non-contact Voltage Detection (NCV)
4.5.1Touch the NCV key to enable the NCV function, and the 
 instrument displays NCV 
4.5.2The NCV sensor is placed close to the measured wire, and the 
 instrument can detect whether the measured wire is gt. 90V 
 ac voltage. When the meter detects the ac power, the meter 
 buzzer alarms and the LCD analog bar displays the induction
 intensity.
Note:
1) Voltage may still exist even if there is no alarm indication. Do not 
 rely on contactless voltage detectors To see if there's a voltage 
 on the wire. Probe operation may depend on socket design, 
 insulation thickness Different types of factors such as the impact.
2 ) In NCV mode, the meter does not measure voltage, resistance, 
 and current at the same tim
