DIGITAL RCD I RCCB I GFCI I ELCB TESTER
IMPORTANT
I.The tester check the time taken for a given selected current to trip the breaker
under test. The test show the phase at tripping (related to the earth terminal).
2.The ELCB Test operates between Line & Earth . Ensure that you operate on
24OVac.
3.The tester is protected against over-temperature. If over-temperature message
appears, allow time for instrument to cool down. During the cool down period, the
instrument switch off automatically to save battery life.
TRIPPING TIME TEST
A preselected current is injected L-E. The value of the current may be selected with the rotary
switch.
• Once the Instrument is switched "ON", the display shows the battery voltage for two seconds.
• Thereafter, the display is ready to wait for the phase selection and to measure the voltage
L-E..
• THE "TEST" BUTTON CAN BE DEPRESSED. once the phase selection has been done and the
voltage has been detected L-E.
• Once Test is depressed, the tester will automatically start the test.
The Instrument displays :
1. The Tripping time (mS) of the RCD (time to break or open the breaker under fault level)
2. The Phase when tripping occurred.
3. The Voltage (Vac) L-E at the start of the test.
4. The approximative percentage error of the current injected ( calculated from the voltage Line
to Earth, compared
To the nominal voltage expected by this model).
Should the RCD not trip within the testing time capability of the instrument, the
display will show T=19.999S and wHold >OVERw, meaning the RCD did not trip
