temperature is down to normal to resume the operation, and the instrument must be
inspected first.
■
There are four types of AC INPUT power source used in this instrument
Switch the voltage selector on the rear panel to the correct position according to the
voltage used locally. Ensure the AC power source is same as marked on the power
switch that located on the rear panel, and the fuse is changed to the appropriate one
when plug in the power cord. Following table lists the fuses for the voltage used:
Center Voltage
Range
Fuse
100V
90V
∼
110V
3.15A Slow/250V
120V
108V
∼
132V
3.15A Slow/250V
220V
198V
∼
242V
1.6A Slow/250V
240V
216V
∼
250V
1.6A Slow/250V
The fuse should conform to the voltage used and replace it when the power cord is
unplugged to avoid electric shock. When replacing the fuse, press the fuse holder inside
the power socket then remove the existing fuse and insert the new one, then plug in the
power cord.
Be sure to use correct fuse when changing it, or it may cause danger
easily.

This instrument operates in AC power source
.
If the power source is unstable in the range selected, it may cause the instrument to act
abnormally or inaccurately. Please use appropriate equipment such as power regulator
to convert it to applicable power source.
■
This instrument uses the power transformer 200VA or above.
If the tested device draws a great amount of current, it may flow in large current (about
10 Ampere) up to 10mS before the judgment of fail and output current cut off. The same
situation may occur before performing the test. Thus it is necessary to pay attention to
the capacity of power cord and the current line linked with other instruments and devices.
■
Storage
The normal temperature range is 18°C~28°C, ≤ 70% RH. The operation may incorrect if
over the range. The storage temperature is -
10ºC~60°C, ≤ 80% RH. If you are not
planning to use it for a long period of time, pack it with the original box for storage. For
the sake of correct test and safety of this instrument, make sure not to store it in a place
with direct sunlight or high temperature, also away from shaky, damp and dusty area.
■
Warming up
This instrument activates at power on; however, in order to meet the accuracy specified
in the specification, please warm it up for 15 minutes or above.
■
Warning Signal of Testing
“DANGER – HIGH VOLTAGE TEST IN PROGRESS, UNAUTHORIZED PERSON KEEP
AWAY”
■
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.
