1. SAFETY PRECAUTIONS
Electricity can cause severe injuries even with low
voltages or currents.
Therefore it is extremely inportant that you read
the following information before using your Digital
RCCB / ELCB Tester.
1.1 This Instrument must only be used and operated
by a competent trained person and in strict
accordance with the instructions.
We will not accept liability for any damage or injury
caused by misuse or non compliance with
instructions and safety procedures.
1.2 Never open Your Digital RCCB / ELCB Tester
except for battery replacement. ( See Battery
replacement section ).
1.3 Always inspect you Digital RCCB / ELCB tester
and test leads before use for any sign of
abnormality or damage. If any abnormal conditions
exist ( broken test leads, cracked case, display
faulty etc... ) do not attempt to take any
measurement or use the tester.
Return your Digital RCCB / ELCB tester to your
nearest Distributor for Service.
1.4 Never replace the protective fuse with any other
than the specified or approved equivalent.
1.5 Your Digital RCCB / ELCB tester has been
designed with your safety in mind. However, no
design can completely protect against incorrect
use. Electrical circuits can be dangerous and/or
lethal when a lack of caution or poor safety
practice is used. Use caution in the presence of
voltage above 24V as these pose a shock hazard.

IMPORTANT
1.The tester check both the point at which the ELCB ( RCD ) trips ( TEST 1-mA ) as well as the time taken for a
given selected current ( TEST 2-mS ) to trip. Both tests show the phase at which tripping occurred.
2.The tester operates between Line and Earth. Ensure that L-E voltage does not exceed 450V.
3.The tester is protected against over-temperature. If over-Temperature message appears. Allow time for the
to cool down.tester
TEST 1 - Tripping Point (Sensitivity)
A ramp current rising in one mA steps is injected.
To save time and reduce power dissipation.The
starting point of the ramp may be selected.
The Instrument displays :
1. The Tripping point (mA) of the ELCB ( Sensitivity )
2. The Phase when tripping occurred.
3. The Voltage ( L-E ) at the start of the test.
Should the ELCB not trip within the current capability
of the instrument, the display will show 1=999mA and
"Hold>OVR", meaning the ELCB did not trip below
999mA. The tripping point is out of the Range of the
Instrument ( or ELCB faulty ) .
TEST 2 - Tripping Time of Breaker
A preselected constant current is introduced L-E
The Instrument displays :
1. The tripping time of the ELCB.
2. The phase when tripping occurred.
3. The voltage ( L-E ) at the start of the test.
Should the ELCB not trip within the testing time
capability of the instrument, the display will show

9. PREPARATION FOR MEASUREMENT
Before testing Always Check the Following.
At Power "ON", check :
–The BAT OK led lit. If the BAT OK led does not lit,
replace batteries.
–There is no visual damage to the Instrument or Test
leads.
–Test lead Continuity with a continuity meter.
10. BATTERY REPLACEMENT
Your Digital RCCB / ELCB Tester's batteries are
situated under the tester.
The BAT OK led (if battery voltage >7.5V ) will
indicate when the battery need to be replaced ( if BAT
OK led does not lit when tester is on ).
Disconnect the Test leads from the Instrument,
remove the battery cover and the batteries.
Replace with eight 1.5V R6 or L6 batteries, taking
care to observe correct polarity.
Replace the Battery cover.
11. FUSE REPLACEMENT
The Fuse is located in the Battery compartment. To
replace the Fuse, proceed as per Battery
replacement to open the Battery cover, then remove
and replace the fuse located on the side of the
batteries . Make sure to place the fuse protection
cover. (small rubberised fuse cover )
Only replace with the same specification fuse. ( 1A

12. SERVICING AND CALIBRATION
Your Digital RCCB. ELCB tester has been factory
calibrated.
However, it is of good practice to have your
Instrument "CERTIFIED" by a National Calibration
Facility and "CHECKED" every year by an
Professional workshop.
12.1 Cleaning and Storage:
Periodically wipe the case with a damp cloth and
detergent; do not use abrasives or solvents.
If the meter is not to be used for periods of longer
then 60 days, remove the battery and store them
separately.
WARNING
To avoid electrical shock or damage to the
meter, do not get water inside the case.
