Carrying Case
Sleeves
Can be stored here.
Removable sleeves can be attached to the metal
pins at the ends of the test leads. To prevent a short
circuit accident, be sure to use the test leads with
the sleeves attached when performing measure-
ments in the CAT III measurement category. Remove
the sleeves from the test leads when performing
measurements in the CAT II measurement category.
For details on measurement categories, see "Mea-
surement categories" in the instruction manual.
• The tipsof the metal pins aresharp, so takecare not to injure
yourself.
• When performing measurements with the sleeves attached,
be careful to avoid damaging the sleeves.
• If the sleeves are inadvertently removed during measure-
ment, be especially careful in handling the test leads to avoid
electric shock.
Measurement Method
Observe the following precautions to avoid electric
shock.
• Always verify the appropriate setting of the function
selector before connecting the test leads. Disconnect
the test leads from the measurement object before
switching the function selector.
• Never apply voltage to the test leads when the Resis-
tance measurement, Continuity check functions are
selected. Doing so may damage the instrument and
result in personal injury. To avoid electrical accidents,
remove power from the circuit before measuring.
• The maximum input voltage is 500 V DC/ACrms or 3 x
106•V/Hz. Attempting to measure voltage in excess of
the maximum input could destroy the instrument and
result in personal injury or death.
• To avoid electrical shock, be careful to avoid shorting
live lines with the test leads.
• For safety, test lead connections must always be
made at the secondary side of a circuit breaker.
• The maximum rated voltage between input terminals
and ground is CAT III (300 V), CAT II (600 V). Attempt-
ing to measure voltages exceeding 450 V with respect
to ground could damage the instrument and result in
personal injury.
To prevent an electric shock accident, confirm that
the white portion (insulation layer) inside the cable is
not exposed. If a color inside the cable is exposed, do
not use the cable. Using the instrument in such con-
ditions could cause an electric shock, so contact
your dealer or Hioki representative for repair.
Periodic calibration and inspecton is necessary in order to en-
sure that this instrument operates according to its product spec-
ifications.
