NOTICEBEFOREOPERATION
1. Unpack the instrument:
After receipt of the instrument, immediately unpack and inspect it for
any damage which might have been sustained when in transportation or
shortage of accessories. If any sign of damage and shortage of
accessories are found, immediately notify the dealer.
2. Environments:
Normally, operational temperature of the instrument is 10°C to 40°C
90%R.H.
(50°F to 104°F). Operation of the instrument outside of this temperature
range may cause damage to the circuits.
3. Check the Line Voltage:
The instrument can operate on any one of the line voltages when in the
below table by inserting the line voltage selector plug in the
corresponding position on the rear panel.
Before connection the power plug to an AC line outlet, be sure to check
that voltage selector plug is set in the correct position corresponding to
the line voltage.
Selector Line Voltage Fuse
115V 100~125V 50/60Hz 6A
230V 220~240V 50/60Hz 3A
4. Hints for operation:
(1) Never place heavy objects on the instrument.
(2) Never place a hot soldering iron on or near the instrument.
(3) Never insert wires, pins or other metal object into ventilation fan.
(4) Never move or pull the instrument with power cord or output lead,
especially never move instrument when power cord or output lead is
connected.
(5) If the instrument is used in a manner not specified by the manufacturer,
the protection provide by the equipment may be impaired.

WARNING!
The following precautions must be observed to help prevent electric
shock.
1. When the instrument is use to make testing. There is always a certain
amount of danger from electrical shock. The person using the
instrument in such condition should be a qualified electronics technician
or otherwise trained and qualified to work in such circumstance.
2. Do not operate the instrument with the cover removed unless you are a
qualified service technician.
3. The ground wire of the 3-wire AC power plug places the chassis and
housing of the instrument at earth ground. Use only a 3-wire outlet, and
do not attempt to defeat the ground wire connection or float the
instrument to do so may pose a great safety hazard.
4. Do not obstruct the ventilation holes in the rear panel. As this will
increase the internal temperature.
5. Never apply external voltage to the output terminal of the instrument.
6. The instrument is designed for INDOOR USE ONLY.
7. This instrument has been evaluated to INSTALLTION CATEGORY II,
POLLUTION DEGREE 2.

MAINTENANCE
GENERAL MAINTENANCE:
1. Preventive maintenance:
Clean and recalibrate the instrument on a regular basis to keep the
instrument looking nice and working will.
2. Cleaning:
Remove any dirt, dust and grime whenever they become noticeable on
the outside cover with a soft cloth moistened with a mild cleaning
solution.
3. Servicing:
If the instrument ever becomes inoperative or damaged, refer servicing
to a qualified repair facility.
FUSE REPLACEMENT:
If the fuse blows, the LED will not light and the instrument will not operate.
Replace only with the correct value fuse. The fuse is located on the rear
panel adjacent to the power cord receptacle. Remove the fuse holder
assembly as follows:
1. Unplug the power cord from rear of the instrument.
2. Insert a small screwdriver in fuse holder slot (located between fuse
holder and receptacle). The fuse holder away from receptacle.
3. When reinstalling fuse holder, be sure that the fuse is installed so that
the correct line voltage is selected.
