Operating Precautions
Operating Precautions
Observe the following precautionary information to ensure that the instrument can be used
safely and in a manner that allows it to perform as described in its specications. Carefully
read the separate document entitled “Operating Precautions” before use. Use of the instrument
should conform not only to its specications, but also to the specications of all accessories,
options, and other equipment in use.
DANGER
Do not touch the section beyond the barrier during operation.
Failure to do so could cause the operator to experience an electric shock.
See “1.2 Part Names” (p.20).
Do not measure any current in excess of the derating.
Doing so can cause overheating of the sensor, resulting in bodily injury, re, or
damage to the instrument.
See “Frequency derating” (p.65).
The maximum measurement current varies with the frequency, and the current
that can be measured continuously is limited. Operating the instrument at less
than this limitation is referred to as derating.
HIOKI CM4141C961-00

13
Operating Precautions
DANGER
Do not apply a voltage across the measurement terminals
when the resistance measurement, continuity check,
diode check, capacitance measurement, or temperature
measurement function is selected
Doing so could cause an electric shock or damage the instrument. To avoid
electrical accidents, turn off the circuit before measuring it.
Conrm that the white portion (insulation layer) inside the
cable is not exposed.
Using the instrument with a color inside its cable exposed could cause the
operator to experience an electric shock.
HIOKI CM4141C961-00

14
Operating Precautions
WARNING
Do not allow the instrument to get wet.
Do not take measurements with wet hands.
Failure to do so could cause the operator to experience an electric shock.
When using the instrument while connected to test leads,
do not make measurements that exceed either of the ratings
indicated on the instrument or on the test leads, whichever is
lower.
Using the instrument to make measurements that exceed either rating could
cause the operator to experience an electric shock.
