damage the instrument.
A
Danger
• The RCD test function of this instrument is only applicable to single-phase
230V /50Hz (power voltage range: 195-253V) circuits;
• The measuring voltage range of this instrument is 30V-600V, 45Hz-65Hz.
• Before using the instrument, please check the test lead carefully.
If the test lead is cracked and the metal wires are exposed, do not use it.
otherwise, serious or fatal hazards are likely to be posed.
• When testing, only under safe conditions can you touch the test lead.
• When testing, do not touch any exposed leads.
• After completing the test, please disconnect the test lead from the power immediately.
&Warning
• During the test, never open the casing of the instrument because of the dangerous
voltage in it. In the event of a malfunction, please refer it to a professional for
inspection and repair.
• If there are any anomalies (such as imperfect display, unexpected test value,
damaged casing, noise during testing, etc.) of the instrument, please hand ii over
to a professional for repair before use.
• Do not use the instrument if your hands are wet.
.&.
Caution
To ensure safety, please use the certified test lead provided by Aegis. It is not
•
recommended to use a third party test lead probe in the CZ20053 instrument.
• Do not expose the instrument to harsh environments such as the sun,
extreme temperatures and humidity.
• Please clean the instrument with a dry cloth. Do not use a damp cloth,
abrasive or solvent to clean it.
• If the instrument is wet, dry the instrument before storage.
Warnings:
1. A possible voltage between the protective conductor and earth will
influence the measurements.
2. The instrument tests the connection between the neutral point of the
distribution system and earth before the test is started. A possible voltage
between the conductor and the earth may influence the measurements.
3. The leakage currents in the circuit following the residual current protection
device may influence the measurements.
4. When the fault voltage is over 50V, "Uf Hi" will be displayed and the test will
stop. The voltage relates to the residual operating current of the protective
device.
5. The earth electrode resistance of the measuring circuit probe cannot surpass 5Ω.
6. The potential fields of other earthing installations may influence the
measurement.
7. Special conditions in residual current protective devices shall be taken into
consideration.
8. Equipment is connected downstream of a residual current protective device

II. Features
1. Intelligent microprocessor chip control: High accuracy, reliability and stability
2. RCD Test Wiring Check:
1) When the wiring is correct, the L-PE and L-N symbols on the left side of the
LCD are always on.
2) If the power is abnormal or no power, the L-PE and L-N symbols on the left
side of the LCD will flash simultaneously.
3) If the power socket is not well grounded or not grounded, the L-PE and N-
PE symbols on the left side of the LCD will flash simultaneously.
4) If the neutral line of the power socket is not well connected or not connected,
the N and N-PE symbols on the left side of the LCD will flash simultaneously.
5) If the live wire and neutral line of the power socket are inversely connected,
the L-PE, L-N, and N-PE symbols on the left side of the LCD will flash
simultaneously.

3. Phase angle selection: The RCD test can be selected to start from a positive
(0 ° ) or a negative (180 ° ) half cycle.
4. Contact voltage alarm: The contact voltage can be limited to UL25V or UL50V.
When the contact voltage is larger than the selected limit value during the
RCD test, the RCD test will be stopped and the LCD will display "Hi" and "Uf'.
5. Auto data hold: After RCD test, the measurement results are kept displayed
until a button press or rotatory switch change.
6. Over range indication: When the test value exceeds the maximum or
minimum value of the current test range, the LCD will display "> current
maximum value" (such as >300ms) or "< current minimum value"
(such as <30V).
7. AUTO RAMP test: Test the trip current and trip time simultaneously.
8. Battery powered: 6 x 1.5V AA alkaline battery. There will be low
voltage indication when the battery voltage falls below 7.2V.
9. Auto Power Off function: The instrument will be power off automatically
after no operation for 5 minutes.
10. Fuse safeguard
11. Double or reinforced insulation for safe design.
12. Backlight function: Press the "LIGHT" key and power on the instrument
to tum the backlight on; In the "VOLTS" position, press the "LIGHT" key
to turn the backlight on/off.
13. L-N voltage measurement: Display L-N input voltage. The display range
is 30V~600V. "---" is displayed when there is no input or the input is
extremely low, "<30V" is displayed when the input is less than 30V,
and ">600V" is displayed when the input is larger than 600V. Press the
"L- N/L-PE" button to switch to L-PE voltage display.
14. L-PE voltage measurement: Display L-PE input voltage. The display
range is 30V-600V. "----" is displayed when there is no input or the input
is extremely small, "<30V" is displayed when the input is less than 30V,
and ">600V" is displayed when the input is larger than 600V. Press the
"L-N/L-PE" key to switch to L-N voltage display.
15. Frequency measurement: Display the input frequency of the
L-PE terminal. In the "VOLTS" position, press the 'VOLT/FREQ" button
to switch the voltage/frequency display.
