Picture of all-sun EM908
Model: EM908



This Socket Tester can be used to determine whether socket wiring is correct or incorrect. It is equipped with an additional RCD tester for testing the operation of RCD whose rating is not more than 30mA. In conjunction with the coding table provided, the ??ve combined indicators indicate the true status of the wiring condition. A clear indication of a PE-error will be shown on the LCD if dangerous contact voltage is present at PE (ground).


·Provides a true ground error indication through the LCD
·Quick recognition of dangerous voltage being present at
the protective earth
·Use of three neon indicators provides rapid detection of
correct /incorrect wiring
·Provides fast and effective RCD test function
