The digital RCD tester is used to test and measure the function parameters of residual current devices (RCDs) in 230-V power grids. Both the trigger time and the tripping current can be detected as the safety-related parameters of RCD switches

• Mains voltage indicator
• PE/L indicator
• Fault voltage indicator (contact voltage)
• Circuit breaker test with a defined error current (10 - 650 mA), tripping time, triggered at negative/positive half-wave, normal/delayed (selective, trigger test time up to 30 s), ramp test
• Striking optical results by changing the color of the display backlight
• Also for testing safety switches
• Confirms to EN 61010-1, CAT-III 600V.
