Warning: Keep away from the instrument after turning off the power and prevent other people
from approaching. Do not immediately disassemble the test circuit. Immediately call our
distributor or agent. High voltage may remain in the interior of the instrument. It is hazardous
for an unqualified person to attempt to troubleshoot any tester problem.
3)
DANGER Indicator Failure
When
【
START
】
key is pressed, there is already a reading on the voltmeter, but the DANGER
indicator is still not lit, it may be that the indicator light is faulty, please shut down the tester
immediately and have it returned to our company to check and repair.
4)
Long-Term Use without Failures
If the high limit is set to 100.0mA (at withstand voltage testing), please pay attention to the
temperature change, suspend use if the ambient temperature exceeds 40
℃
, wait till the temperature is
returned to the normal level, please be sure to check.
5)
Replace the Fuse
To prevent electric shock, be sure to turn off the power switch and unplug the AC power cord before
checking and replacing the fuse, remove the fuse holder located in the power socket, take out the fuse
and press the new fuse into the fuse holder, then press into the power outlet.
!
WARNING:
Make sure the fuse used is identical to the ones described on the manual,
i
ncluding
the shape, grade, characteristics etc. If different type of fuse is used or short circuit, then the tester
may be damaged.
6)
AC Power source
The AC input power used by this tester is 100V
~
240VAC, frequency is 47Hz
~
63Hz. If the power
supply is very unstable, this will cause the action inaccurate or action abnormal, therefore, please use
an appropriate device to convert to a stable power source, such as a power stabilizer.
7)
Output Power 500VA
When the DUT draws a large amount of current, prior to the determination of the defective products
and output current cut off, there is possible inflow of large current (approximate tens of amps) which
can last tens of milliseconds, the same situation may also apply prior to testing, therefore, must pay
attention to the capacity of the power cord and the applicable current line that is used together with
other instruments or devices.
8)
Keep Test Lead Far Away from the Panel
When in test, please keep the high voltage cable or DUT at least 30cm away from the panel, avoid
high voltage interference monitor.
9)
Precautions When Connecting Automation Equipment
The grounding system of the tester and the automation equipment must be connected together.
Install the anti-interference magnetic ring on the two ends (device output end and DUT end) of
high voltage cable and RTN/LOW test line, and wind the wire at least more than one turn.
High voltage cable and RTN/LOW test line must be separated from the control wire.
High voltage cable and RTN/LOW test line must be kept at an appropriate distance from the
tester/panel.
