Aegis CZ20053 Operating Manual

AEGIS
CZ20053
RCD Tester
1. Safety Instructions
This operating manual includes the operation guidance and safety
instruction when using the CZ20053 tester. Please read before use.
Caution
● Before using the tester, please read and understand the operating
manual.
● Keep the operating manual intact, and accessible for reference
during the process of testing.
When using the tester, operator must follow the testing
●
procedure as mentioned in the operating manual.
● Carefully read the operating manual regarding the safety information.
● Ensure you follow all the related safety instructions, otherwise it
may cause accidents or damage the tester.
Safety sign " " has three meanings in this manual, user needs to
pay attention to the sign " ".
Danger-----identifies conditions and actions that most likely
pose severe or fatal hazard(s).
Warning---identifies conditions and actions that may pose
severe or fatal hazard(s)
Caution---identifies conditions and actions that may cause
minor injury or damage to the tester.
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 tester needs servicing or repairing, please
contact your Aegis service agent.
● If the test instrument appears abnormal (for example 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.
danger, warning, caution
double or reinforced insulation
Grounding
2. Features
● Suitable for Use on 230V/50Hz single-phase line (operating
voltage: 196~253V);
● Micro Processor IC to 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.
● Auto Ramp Test: Test the trip current and trip time
simultaneously.
● Power-Off Warning Indication: The internal buzzer will alarm after
operating greater than 3 minutes.
● Power Save and Environment-Friendly: Powered directly by
the tested circuit (Power 230V/50Hz). No need to use batteries;
● Fused Protection
● Double or Reinforced Insulation for safe design.
