This compact hand held RCD tester is designed for professional use to obtain accurate values of  'Trip Time' with the selection on a dial switch of the trip current.

• Resistors are used to pass the trip current between earth and active therefore a correction factor in percentage is available on the display for adjustment according to the line voltage.
• The trip time is measured to a maximum of 3.000 seconds, while the fault current is selectable on a range from 3 to 500mA.
• The unit has been designed for ease of operation whilst maintaining safety, reliability and accuracy.

Features

• Residual Current Device (RCD) or ELCB trip time tester with LED indication for power, battery and mains polarity
• Simply select earth leakage resistance test value
• Displays adjustment percentage for high and low voltage
• Suitable for 10A and 30 mA RCDs

Three basic tests

•    Wiring test
•    Line Voltage to Earth
•    Tripping time
•  Menu driven and easy to use
• LED wiring check function to check wiring prior to test
• Test angle selection - 0 or 180°
• Dynamic battery check
• Microprocessor controlled
• Tough rugged meter, designed to give accurate measurements in harsh environments

To complete the test:

•  Connect the unit and check that the LED display indicates the wiring is correct
• Check that the line voltage is within tolerance
• Set the trip current on the selector and hit the test button
• Once the test is complete, the operator can view the following on the LDC display:
•    Circuit voltage
•    Percentage error current (from nominal voltage)*
•    Disconnection time
•    Polarity at opening
•    Over Temperature Protection
