○Read through the following safety instructions contained in this
manual before using the instrument.
DANGER
¡Never make measurement on a circuit in which electrical potential to
ground over 600V exists.
¡Do not attempt to make measurement in the presence of flammable
gasses. Otherwise, the use of the instrument may cause sparking,
which can lead to an explosion.
¡Never attempt to use the instrument if its surface or your hand is wet.
Otherwise, you may get electrical shock.
¡Never open the Bottom case and Battery cover during a measurement.
WARNING
¡ Never attempt to make any measurement if any abnormal conditions,
such as broken case and exposed metal parts are present on the
instrument or test lead.
¡ Do not install substitute parts or make any modification to the
instrument. Return the instrument to your local Kyoritsu distributor for
repair or re-calibration.
CAUTION
¡ Always set the Function switch to the appropriate position before
making measurement.
¡ Do not expose the instrument to the direct sun, high temperatures and
humidity or dew.
¡ This instrument is designed for in-door use. It can be used under the
temperature between 0℃ and 40℃ without impairing its safety
characteristics.
¡ This instrument doesn't have dust/water-proof construction. Do not use
the instrument in dusty area or where it easily gets wet. It may lead to
failure of the instrument.
¡ Set the Function switch to "OFF" position after use. Remove the
batteries if the instrument is to be stored and will not be in use for a
long period.
○Measurement categories (Over-voltage categories)
To ensure safe operation of measuring instruments, IEC61010
establishes safety standards for various electrical environments,
categorized as CAT.l to CAT.IV, and called measurement categories.
These are defined as indicated below.
Higher-numbered categories correspond to electrical environments with
greater momentary energy, so a measuring instrument designed for
CAT.III environments can endure greater momentary energy than one
designed for CAT.II.
