3.1 Usage Precautions
Safety Precautions
• Before using the instrument, be sure to thoroughly read "Safety Precautions"
on pages 4 and 5.
• Do not remove the casing from the instrument.
Some parts inside the instrument are extremely dangerous because
they use a high voltage. When the instrument needs an internal inspection
or calibration, contact YOKOGAWA or the dealer from whom you purchased
the instrument.
• In the case of an abnormality
If the instrument begins to emit smoke, give off an unusual odor,
or show any other signs of an abnormality, immediately turn off the power
switch. If you are using an AC adapter, unplug the power cord from the
outlet. Also turn off any object under test that is connected to the input
terminals.
General Handling Precautions
• When carrying the instrument
Turn off the power to the object under test. Turn off the power to the
instrument and unplug the power cord from the outlet if you are using
an AC adapter. Then, disconnect all lead cables from the instrument.
When carrying the instrument, use the carrying case.
• Keep input terminals away from electrically charged articles as they may
damage the internal circuitry.
• Do not allow volatile chemicals to come into contact with the casing or
operation panel. Also, do not allow the instrument to come into contact with
any rubber or vinyl products for prolonged periods.
Since the operation panel is made of thermoplastic resin, be careful not to
let it come into contact with any heat sources such as a soldering iron.
• Before cleaning the case and operation panel, make sure that the power
cord is unplugged from the outlet if you are using an AC adapter.
Dampen a clean soft cloth with water and gently wipe the surface of the
casing and panel. Water getting inside the instrument may result in a failure.
• If the AC adapter will not be used for a prolonged period, unplug the power
cord from the outlet.
• For precautions on handling dry batteries, refer to "3.2.1 Using Alkaline
Batteries."
• Do not use the instrument with the cover for the battery holder left open.
