NOTICE BEFORE OPERATION
1. Unpack the instrument:
After receiving the instrument, immediately
unpack and inspect it for any damage which
might have occured during transportation or
shortage of accessories. If any signs of damage
and/or shortage of accessories are found, notify
the dealer immediately.
2. Environments:
Normal operating temperature of the instrument
is 10°C to 40°C (50°F to 104°F). Operation of the
instrument outside of this temperature range may
cause damage to the circuits.
Do not use the instrument in a place where
strong magnetic or electric fields exist. Such
fields may disturb the measurement.
3. Check the Line Voltage:
The instrument can operate on any one of the
line voltages shown in the table below by
inserting the line voltage selector plug in the
corresponding position on the rear panel.
Before connecting 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.
CAUTION: The instrument may not properly
!
operate or may be damaged if it is
connected to an AC line with the wrong
voltage. When line voltages are changed,
replacement of the fuses is also required.
Selector
Line Voltage
115V
100~125V 50/60Hz
230V
220~240V 50/60Hz
Hints for operating the instrument:
Observe the following suggestions for successful
instrument 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 objects
into the ventilation fan.
4. Never move or pull the instrument with power
cord or probe cord.
Never move the instrument especially when the
power cord or signal probe is connected to a
circuit.
5. If the instrument is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
1. When the instrument is used for testing, there is
always a certain amount of danger from electrical
shock. The person using the instrument should
be a qualified electronics technician or otherwise
trained
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
Fuse
not attempt to defeat the ground wire connection
or float the instrument. Doing so may pose a
600mA
great safety hazard.
300mA
4. Do not obstruct the ventilation holes in the rear
panel, as this will increase the internal
temperature.
5. Never apply an external voltage to the output
BNC connector of the instrument.
6. Excessive voltage applied to the input BNC
connector may damage the instrument.
