1. 

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 

T

est operates between Line & Earth. Ensure that you operate on operating V

oltage (V

ersion 

A, B, C or D).

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 of

f 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 show the battery voltage for about two seconds.

 Thereafter

, the display is ready to wait for phase selection and to measure the voltage L-E..

 THE “TEST” BUTT

ON CAN BE DEPRESSED. Once the phase selection has been done and the voltage has been

   detected L-E. .

 Once 

T

est is depressed, the tester will automatically start the test.

Should the RCD not trip within the testing time capability of the instrument, the display will show T=2.999S

and “Hold >OVER”, meaning the RCD did not trip below 19.999S. The tripping point is out of the Range of 

the instrument (or RCD faulty).

TEST PROCEDURE

1. Insert the leads into Instrument.

2. Switch Instrument “ON”.

3. Select the current using the rotary switch.

4. Select positive (0º) or negative (180º) edge to start.

5. Connect the tester to the circuit under test.

6. 

The tester measures and display the voltage L-E.

7. Check wiring. Proceed only if wiring is correct.

8. Depress “T

est” button to automatically test.

w

 T

est start immediately if voltage is present.

w

 The 

T

est stops automatically when Breaker trips.

w

 T

est results are shown on the display

w

 When Instrument is utilized on two wires (L-E), wiring check

   must be disregarded.

w

 This instrument is “Domestic rated”.

Once “T

est” button is depressed :

6. RCD TEST - TIME DELAY :

Turn instrument “ON” by pressing the “TEST-ON” button.

The L.C.D. display will come to the following Screen :

The instrument will detect and show the battery voltage

when power ON.

The tester wait for voltage to be measured

and phase selection can be changed.

Phase selection has been changed so

that testing will start on a negative going edge.

The leads have been connected and the voltage

between L-E is 234Vac (version B shown in this example).

“Test” button has been depressed. Test in progress since 2.999s.

The voltage between L-E was 234V before testing started.
