Observe the following to avoid electric
shock and short circuits.
• Before connecting or disconnecting the
test leads to/from the instrument, be
sure to disconnect the test leads from
the object under test and turn off power.
• Do not perform measurement with the
battery cover removed.
• Do not use the shut-
ter if it is broken.
• To avoid electric
shock, do not
remove the instrument's case. The inter-
nal components of the instrument carry
high voltages and may become very hot
during operation.
• Do not use the instrument in environ-
ments containing ignitable gases,
explosive powders, etc. (Risk of explo-
sion)
• Do not place the instrument on an
unstable table or an inclined place.
Dropping or knocking down the instru-
ment can cause injury or damage to the
instrument.
• Do not use the instrument with circuits
that exceed its ratings or specifications.
Doing so may damage the instrument or
cause it to become hot, resulting in
bodily injury/electric shock.
• Before using the instrument, inform
those around you of your intention to
do so.
• To prevent instrument damage or
electric shock, use only the screw for
securing the battery cover in place that
are originally installed. If you have lost
a screw or find that a screw is damaged,
please contact your Hioki distributor for
a replacement.
