ANENG VD410A AC 12~1000V Dynamic Digital Display Non-contact Induction Electric Pen Voltage Test Pen AC Voltage Detectio

Operation instructionsPower on offPress the power button and last over 1 sec it will show POWER and then u can use it for testing Press the power button again it will be off Sensitivity switchThe pretermission when power on is low sensitivity status Press the sensitivity switch flashlight button for less than 1 sec then u can switch it from high sensitivity and low sensitivity When it shows S it means high sensitivity and if the light is off then it is low sensitivity Pls note the high sensitivity range is 12 1000V and low sensitivity range is 48 1000VFlashlightPress the sensitivity switch flashlight button and last for over 2 sec the flashlight will be on And if u press the button again for over 2 sec the flashlight will be off soon If without any operation or signal it will be auto power off in 3 mins AC Voltage detectionPut the probe close to the AC voltage the pilot light will be on and the analog phasedata will change according to the voltage signal the buzzer will be also changed If the voltage is below 36V it will show green light if above 36V it will show red lightdanger signal Normally when using the tester pen to distinguish the zero line pls test the two lines or 3 lines the one which shows the largest data is the live line the one smaller is the zero line or earth line Note 1 If the socket design is different or the circuit is wrong so you can t distinguish the zero line according to the signal pls be very careful and this is a spe
