Before Connecting to the Lines to be Measured
• To avoid short circuits and potentially life-threatening hazards, never attach the
current sensor to a circuit that operates at more than the maximum rated volt-
age to earth. Also, do not perform measurement around a bare conductor.
(See your current sensor's instruction manual for its maximum ratings.)
• Do not use the instrument to measure circuits that exceed its ratings or specifi-
cations. Damage to the instrument or overheating can cause bodily injury.
To avoid electrical hazards and damage to the instrument, do not apply voltage
exceeding the rated maximum to the input terminals.
• Do not short-circuit two wires to be measured by bringing the voltage cord clip
or current sensor into contact with them. Arcs or such grave accidents are
likely to occur.
• To prevent a short-circuit or electric shock, do not touch the metal part of the
connecting voltage cord tip.
• To prevent electrical shock and personnel injury, do not touch any input termi-
nals on the VT (PT), CT or the instrument when they are in operation.
Connect measurement lines to Model L1000 Voltage Cord securely. If a terminal
is loose, the contact resistance will increase, resulting in overheating, equipment
burnout, or a fire.
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 authorized Hioki distributor or reseller as soon as possible.
Continuing to use the instrument may result in fire or electric shock.
