Socket leakage detector, digital display voltage/line detection/leakage detection/double insulation. Comprehensive functions, plug and play. VA color screen digital display, the screen value can be clearly seen in a dark environment. Leakage test protection function, under normal and correct conditions, "RCD leakage switch test" if : leakage protection is normal, if not : please contact professionals to inspect . Warning: Please turn off all electrical appliances before using this function, and do it with permission to that power failure not cause any harm. Insulation flame retardant safety protection, the shell is made of flame retardant materials, and the internal copper wire is highly conductive and generates less heat. Universal 10A three-hole plug, easily detect whether the circuit wiring is correct. Test status analysis, you can compare the information displayed on the instruction manual screen according to the measurement results. Warning: To avoid or injury caused by incorrect readings, the battery must be replaced immediately when the battery undervoltage symbol appears on the instrument.
