This operating manual includes the operation guidance and safety
instruction when using the CZ20053 tester. Please read before use.
Caution
●Before using thetester, please read and understand theoperating
manual.
●
●
Keep the operating manual intact, and accessible for reference
during the process of testing.
When usingthe tester, operator must follow the testing
procedure as mentioned in the operating manual.
● Carefully read the operating manual regarding the safety information.

Danger
● This test instrument is only suitable to use on single phase circuits,
230V+10%-15%. (Operational Voltage Scope: 196 – 253 V)
● To avoid potential electric shock or personal inquiry, do not use
the test instrument or test leads if they appear damaged or have
exposed metal parts. If test instrument is not operating properly
or in doubt, please have the instrument serviced.
● Do not touch any part of the test lead while the test instrument is
testing.
● Remove the test leads away from the power circuit after the
tests are completed. Do not keep the test leads connected to the
power circuit after the tests are completed.
Warning
● Do not open or disassemble the tester during the test
measurements. The high voltage present in the tester may
endanger the user. If testerneeds servicing orrepairing, please
contact your Aegis service agent.
●If the test instrument appears abnormal (forexample LCD
displaying incorrectly, incorrect calculation, housing damage, noise
issue during measurements etc.). Please contact your Aegis
service agent.
● Do not use the tester if your hands are wet.
Caution
● Ensure the test lead probe (use only Aegis specified test leads)
are inserted into the corresponding port in order to provide a
safe measurement. It is not recommended to use third party
test lead probe on the CZ20053 tester.
● Do not expose the tester to extreme temperatures and wet environment.
● Soft cloth and mild detergent should be used to clean the surface of
the tester. No abrasive and solvent should be used when servicing.
● If wet, dry the tester before storing it.
This test instrument has the following signs, please pay attention to
the content when using.

double or reinforced insulation
Grounding
2. Features
● Suitable for Use on 230V/50Hz single-phase line (operating
voltage: 196~253V);
●Micro Processor ICto maintain high accuracy, reliability
and stability;
● Wiring Check: Three – LED indication
When P-E and P-N green LEDs are illuminated and red LED is
off, the wiring is correct. Otherwise it indicates wiring (P and N
are reversed or bad grounding) is incorrect.
● Phase Angle Selection: The tests can be performed at positive
0 or negative 180 phase angles.
● Over-Load Indication: “OL mS” shows when trip time exceeds
Max. test time
● Auto Data Hold: The test results will be maintained for a while after
the tests have been completed.

This instruction manual is subject to change without notice.
(1) Test Measurements
Test Lead Connections
Insert the three plug connectors of test lead into the termin-
als of the Tester. Red to L, Green to E, Blue to N. Then connect
the other end of the test lead into the tested circuit
(power socket 230V/50Hz).
Danger
● Do not touch any exposed metal or conductors during these test
operations.
●Internal components in the tester may get hot during its testing.
If the tester is operated continuously for a long time, it may
cause damage to the unit or other hazards. It is not
recommended to use the tester for a continuous long period of
time or continuous tests on production lines in RCD factories. It
is only suitable for sampling precision tests.
● When using trip currents of 300mA or 500mA please allow 5
minutes between tests. To allow the tester to cool.
6. Maintenance & Repair
6.1 Cleaning the Casing:
Clean the surface of the tester with dry soft cloth; DO NOT USE
alcohol or solvents as it may cause corrosive damage to the LCD.
Protect the test instrument from any moisture.
6.2 Repair
Please contact your Aegis sales representative if the following
issues occur:
A. The test instrument’s casing is broken or the components are
damaged.
B. LCD display works abnormally.
C. Unexpected data occur under normal use.
D. The buttons do not function normally.
E. Noise occurs during tests.
(4) Taking RCD Tests
4.1 Set the rotary switch to test parameters
● Non-Tripping -------------------×1/2: Max. trip time up to 1000ms;
● Tripping -------------------------×1: Max. trip time up to 1000ms(Except
500mA);
● Tripping -------------------------×1(500mA): Max. trip time up to 300ms;
● Fast Tripping------------------- ×5 (only 10, 20, 30mA ): Max. trip time
up to 1000ms;
●AUTO RAMP Test: 20%~110%ofrated trip current
(I△n), Max. trip time up to 300ms.
4.2 Press TEST button
● Non-Tripping Test -------The RCD should not trip.
● Tripping --------------------The RCD should trip.
● ×5 Fast Tripping: ----------- The RCD should trip.
● AUTO Ramp Test: ---------- The RCD should trip, trip time and trip
current are displayed simultaneously
4.3 Press PHASE (0 /180 ) button to set the phase angle and repeat
4.2 to determine the fastest trip time.
4.4 Press PHASE to change the phase angle and repeat 4.2
4.5 When the tests are finished, disconnect the test lead from the
tested circuit immediately.
(2) Wiring Check
Check the wiring status by identifying three LEDs. If P-E and P-N
green LEDs are illuminated and red LED is off, it indicates the
wiring is correct. Otherwise wiring is wrong due to reverse
connection between L and N terminals or bad grounding. Please
unplug the test leads, check and correct the relative circuits until
correct wiring LED indication is obtained.
(3) Press I△n button to adjust the trip current(I△n) to the same
current rating as the RCD that is under test. The set trip current
will be shown on lower part of LCD.
Default value: I△n----------------- 30mA
0 /180 ----------- 0
Caution: Reverse connection between L and N terminals during
wiring check may cause RCD to trip. Please check and correct
the circuits until the wiring indication is obtained before you
proceed to next operation.
Danger
Do not proceed into the test (press TEST button) if the
wiring is incorrect, otherwise it may cause error to the result or
other hazards.
