Versatile Design: Intelligent voltage tester pen has many functions including line fireline identification, line breakpoint finding, socket polarity detection, leakage current switch detection, AC voltage measurement, voltage induction measurement functions.
How does it display: The 2000-bit LCD display shows the test data clearly. Besides, the pen is equipped with different colors of backlight, reminding you of paying attention to the values.
Leakage Current Switch Test: If the line is correct, you just press the "leakage test" and the line is tripping, it will show that the leakage ing function is normal; if there is no tripping, please contact the duplicator for maintenance.
