Description of RCD Tester
MS5909 is a leakage switch tester controlled by intelligent microcontroller chip, which has the characteristics of high precision, robustness, durability and easy operation. This instrument can be used in 220V single-phase power system and 380V three-phase power system. It can not only test the operating time and operating current of the leakage light, but also has the test function of wiring inspection, fault voltage and system voltage. The tester has the functions of phase Angle selection, overtemperature detection, low voltage detection, LCD backlight and automatic shutdown. This is a detection instrument for leakage protection devices in various occasions, easy to carry and use.
- Function - Trip current measurement/Trip time measurement/Data storage/RCD measurement/Auto Power Off/Over temperature test/Back light/Single-phase voltage measurement/Three-phase voltage measurement/Phase angle selection.
- Data storage - Press the MEMO key to store the current displayed data, up to 99 sets of data can be stored.
- Three-phase mode testing is not only applicable to three-phase 380V/50Hz power system, but also to single-phase 220V/50Hz power system.
