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 w
hile 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.

arning
● Do not open or disassemble the tester during the test
measurements. The high voltage prese
nt in the tester may
endanger the user. If tester needs
servicing
or repairing, please
contact
your
Aegis service agent.

port in order to provide a
safe measurement. It is not recommend
ed to use third party

● Do not expose the tester to extreme temperatures and wet env
ironment.
● 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.

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.
