Features CLEAR DISPLAY: Voltage tester with HD LCD display, the degree is clearer, the value of the test screen is clearly visible at a glance in the dark environment MAIN FUNCTIONS: Voltage test pen can quickly distinguish and detect AC voltage value, pen tip tests AC voltage (leakage), quickly distinguish conductor voltage (leakage), line power failure detection WIDE APPLICATION: Intelligent sensor voltage tester is widely used in mechanical repair, electrical maintenance, household use, car repair, etc. NEUTRAL LIVE WIRE SMART JUDGMENT: Select the live neutral wire distinction function, insert the pen needle into the hole for identification, without the identification of with traditional touch, electricity measurement is more secure ROUTE SWITCH POINT DETECTION: In non-NCV touch voltage detection mode, the breakpoint position is eliminated along the path when a single wire is loaded 1. CLEAR DISPLAY: Voltage tester with HD LCD display, the degree is clearer, the test display value is clearly visible at a glance in the dark environment 2. MAIN FUNCTIONS: Voltage test pen can quickly distinguish and detect AC voltage value, pen tip tests AC voltage (leakage), quickly distinguish conductor voltage (leakage), line power fault detection 3.
