KKmoon MY5908 Digital LCD Backlight Circuit Analyzer True RMS AC Voltage RCD GFCI Electrical Tester Line Fault Test Device This circuit analyzer is a special test device designed for AC low-voltage distribution line quick fault location, With simple operation, accurate measurement and other features, it can detect multiple problems on a line, such as causing to electric shock, electrical fire, abnormal operation of equipment, etc. Features: True RMS measuring AC voltage. Artificial load 5A, 8A, 10A measuring line drop. Measuring phase voltage, neutral line (zero line) voltage to earth, peak voltage, frequency. Measuring phase (live line), neutral line (zero line), earth line conductor impedance. Identifying 3-wire socket connection mode (zero for left and live for right, whether there is earch line or not). Testing the reliability of residual current device (RCD), GFCI action, and response action time. Digital LCD display with backlight and data hold function, clear at a glance, easy to read no matter in the day or at night. Note: 1. Please read the user manual carefully before use. 2. Color and size may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
