Usage Notes
10
• To avoid electrical accidents, confirm that all connections are secure. The
increased resistance of loose connections can lead to overheating and fire.
• Ensure that the input does not exceed the maximum input voltage or current to
avoid instrument damage, short-circuiting and electric shock resulting from
heat building.
• To avoid electric shock when measuring live lines, wear appropriate protective
gear, such as insulated rubber gloves, boots and a safety helmet.
When the instrument's power is turned off, do not apply voltage to the instrument.
Doing so may damage the instrument.
While Measuring
If an abnormality such as smoke, strange sound or offensive smell occurs, stop
measuring immediately, disconnect from the measurement lines, turn off the
instrument, unplug the power cord from the outlet, and undo any changes to the
wiring. Contact your dealer or Hioki representative as soon as possible. Continu-
ing to use the instrument may result in fire or electric shock.
