Precaution before Use
17. The tester includes four kinds of AC INPUT power. Please accord with local voltage
turn the voltage selection switch on rear panel to the right position.
When you want to plug in power cable, be sure input AC power scale is the same as rear
panel switch power. Also need to replace fuse, the following table is voltage and fuse
which be used.
Scale Nominal Value Range Fuse
90V ∼ 110V
100V
90V ∼ 110V
5A Slow/250V
108V ∼ 132V
120V
108V ∼ 132V
5A Slow/250V
198V ∼ 242V
220V
198V ∼ 242V
2.5A Slow/250V
216V ∼ 250V
240V
216V ∼ 250V
2.5A Slow/250V
Be sure used voltage when replace fuse. Only can replace fuse under
power-disconnected status by flat type screwdriver.
WARNING
Please use correct specification when replace fuse or may cause
hazard.
18. Normal operation of the unit is AC power. If power is unstable within selection voltage
range, it may cause the unit function is not actual or abnormal. Therefore, please use
appropriate equipment turn to suitable power such as power stabilizer.
19. The tester use power transformer is over 200VA. When DUT drawing mass current.
Before deadline of no good judgment and output current, it may flows mass current
(about ten amperes) up to ten milliseconds. Before processing test may be the same
condition. Please notice the capacity of power cord and the current cable of linking with
other instrument or equipment.
20. Storage
The unit normal operation temperature humidity range is 5°C ∼ 40°C, 75% RH. If over
this range then function may malfunction. The unit storage temperature range is -10°C
∼ 50°C, 80% RH. If you don’t use it for a long time, please use original material packing
and then store it. For correct test and safety, please keep it from direct sunlight or high
temperature, vibration, humidity and dusty place.
21. Warm up
All functions of the tester are activated when the power switch is turned on. However, to
attain the precision in the specification, please warm the instrument over 15 minutes.
22. Warning signal of testing
"DANGER – HIGH VOLTAGE TEST IN PROGRESS, UNAUTHORIZED PERSON
KEEP AWAY"
23. Keep test cable away from the panel
Please keep the high voltage cable or the DUT away from the panel at least 30 cm
during operation to avoid the display interference caused by high-voltage discharge.
24. Notices for connecting automated device
y The grounding system of the device and the automated station should be connected
together.
y Add anti-interference iron core to the high voltage cable and the 2 ends (device
output and DUT) of RTN/LOW test cable with winding at least 1 circle.
y The high voltage and RTN/LOW test cable must be separate from the control cable.
y The high voltage and RTN/LOW test cable must keep proper distance from the
tester panel.
