<b>Operation description:</b> <br><br> <b>Acousto-optic discrimination of Live or Null Wire:</b> <br><br> <b>- Live Wire Testing:</b> <br> When the sensor end of the measuring pen is close to the object to be measured, the fast-paced buzzing alarm of the tester gives out an alarm sound, and the screen flashes red light, indicating that the test is a <b>LIVE WIRE.</b> <br><br> <b>- Null Wire testing:</b> <br> When the sensor end is close to the object to be measured, the slow-paced buzzer alarms, and the display screen flashes green light, indicating that the tested line is <b>Null Wire.</b> <br> <b>This product has more comprehensive functions:</b> <br> For testing AC Voltage<br> Recognition of Live/Null Wire<br> Triple alarm of sound, light and screen<br> Energy-saving and bright LCD screen<br> High and Low Voltage Signal Indicator <br> Buzzer alarm - loud and sensitive<br> White LED lighting - - energy saving, convenient <br> Auto power off<br> Switch key<br> Good Sensitivity of NCV Sensor<br> <b>Technical Specifications:</b> <br> Dual Range of AC Voltage: 48V-1000V/12V-1000V<br> Frequency: 50Hz / 60Hz<br> Alarm Mode: Sound and light alarm<br> Electric Torch: LED illumination <br> Low-voltage indicator lamp: Yes<br> Power Source: 2 x 1.5V AAA Batteries<br> Security Level: CE CAT. III 1000V / CAT. IV 600V<br> Service Temperature: 0-40 <br> Storage Temperature: -10-50 <br> <b>* AC voltage detection </b> <br> The voltage detector probe is placed near the AC voltage. When the voltage is induced, the signal light will be lit. The display of the screen will become higher or lower as the voltage signal intensity is induced, and the beep hint will become faster or slower with the signal intensity. <br><br>
