Feature:1. A tester that can measure three-phase electricity, non-contact phase sequence detection, divided into three ways of left-handed/right-handed/disordered2. Provide null and firing line test, sound and light alarm, results are clear at a glance, support high/low sensitivity switch3. Support circuit breakpoint detection, power check, clear circuit distribution4. Long press the function button to turn on the flashlight lighting, worry-free measurement in dark environments5. After about 5 minutes of no induction or no operation, the tester will automatically shut down. When the battery voltage is low, the display will show a reminder symbolHow to Use:After power on, the display shows the "P" symbol and enters the phase sequence detection state;1. "A" flashes on the display. Place the sensing probe close to the first phase line and wait for a beep;2. “B” flashes on the display. Place the sensor probe close to the second phase line and wait for the buzzer to sound;3. "C" flashes on the display screen, close the sensor probe to the third phase wire, and wait for a long beep;At the end of the test, the display screen will display the test result on the display screenSpecification:Item Type: Induction Electric PenModel: TA13ANon-Contact Induction Voltage Range: 12-1000V, 50/60HzPhase Sequence Induction Voltage Range: 90-400V, 50/60
