■ Operating Precautions
Precautions for Safe Use of the Instrument
● When using the instrument for the first time, be sure to read
the instructions given on pages vi to ix 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
assembly.
● 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.
General Handling Precautions
● Before carrying around the instrument turn off power to the object
under 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 operation panel, as the panel is made of
thermoplastic resin.
● Before cleaning the instrument’s case or operation panel disconnect
the power cord plug from the wall outlet if you are using an AC adapter.
Use a soft, clean cloth soaked in water and tightly squeezed to gently
wipe the outer surfaces of the instrument.
Ingress of water into the instrument can result in malfunction.
