Precautions for Safe Use of the Instrument
●
When using the instrument for the first time, be sure to read the instruc-
tions given on pages iv and v of the section, “Precautions for Safe Use
of the Instrument.”
●
Do not open the instrument’s case.
Opening the case is extremely hazardous, as the instrument contains
high-voltage parts. Contact the vendor from which you purchased the
instrument, for a service of inspecting or adjusting the internal assem-
bly.
●
In case of failure
Should the instrument begin to emit smoke, give off an unusual odor, or
show any other anomaly, immediately turn off the POWER key. If you
are using an AC adapter, disconnect the plug from the wall outlet. Also
cut off power to the object under test that is connected to the input
terminals. Then, contact the vendor from which you purchased the
instrument.
●
AC adapter
Use an AC adapter dedicated to the instrument. Avoid placing any load
on the AC adapter, or prevent any heat-emitting object from coming
into contact with the adapter.
General Handling Precautions
●
Before carrying around the instrument turn off power to the object un-
der test, and then the POWER key of the instrument. If you are using
an AC adapter, disconnect the power cord from the wall outlet. Finally,
detach all lead cables from the instrument. Use a dedicated carry case
when transporting the instrument.
●
Do not bring any electrified object close to the input terminals, since the
internal circuit may be destroyed.
●
Do not apply any volatile chemical to the instrument’s case or operation
panel. Do not leave the instrument in contact with any product made of
rubber or vinyl for a prolonged period. Be careful not to let a soldering
iron or any other heat-emitting object come into contact with the opera-
tion panel, as the panel is made of thermoplastic resin.
