• This instrument is designed for use indoors.
It can be operated at temperatures
between 0 and 40°C (32 and 104°F) without
degrading safety.
• To avoid damage to the instrument, protect
it from physical shock when transporting
and handling. Be especially careful to avoid
physical shock from dropping.
• If the protective functions of the instrument
are damaged, either remove it from service
or mark it clearly so that others do not use it
inadvertently.
• Calibration and repair of this instrument
should be performed only under the super-
vision of qualified technicians knowledge-
able about the dangers involved.
• Never modify the instrument. Only Hioki
service engineers should disassemble or
repair the instrument. Failure to observe
these precautions may result in fire, electric
shock, or injury.
• Place the cover on the tester when not in use.
• After use, always turn OFF the power.
• To avoid damage to the tester, do not connect
an external device to the USB terminal or the
temperature sensor terminal.
• Standby State
The use of "standby state" in this manual
means that measurement is not being
performed and that no parameters are
set. This includes the state in which
is on.
• If the tester is exposed to an abrupt large
variation in temperature, condensation
may occur, resulting in measurement
errors.
Leave the tester in a new environment for
a while before starting measurement.
