Measurement categories
To ensure safe operation of measurement products,
IEC 61010 establishes safety standards for various
electrical environments, categorized as CAT II to
CAT IV, and called measurement categories.
CAT II : Primary electrical circuits in equipment
connected to an AC electrical outlet by a
power cord (portable tools, household
appliances, etc.) CAT II covers directly
measuring electrical outlet receptacles.
CAT III : Primary electrical circuits of heavy
equipment (fixed installations) connected
directly to the distribution panel, and
feeders from the distribution panel to
outlets.
CAT IV: The circuit from the service drop to the
service entrance, and to the power meter
and primary overcurrent protection device
(distribution panel).
Using a measurement product in an environment
designated with a higher-numbered category than
that for which the product is rated could result in a
severe accident, and must be carefully avoided.
Use of a measurement instrument that is not CAT-
rated in CAT II to CAT IV measurement
applications could result in a severe accident, and
must be carefully avoided.

Precautions
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various

Precautions
――――――――――――――――――――――――
DANGER
To avoid accidents, when using other
measurementdevices with this one, observe the
usage precautions described for each device.
When using a measurement instrument that
does not provide isolation between its input
terminals and chassis or other input terminals,
please pay attention to the following points.
If a signal is applied to an input terminal other
than that to which the current probe is
connected, do not connect the ground-side
terminal to any non-ground potential.
Otherwise, short-circuit current will flow
through the current probe or this device from
the ground terminal, which could cause an
electrical accident or damage.

WARNING
To avoid electrical accidents and to maintain the
safety specifications of this instrument, connect
the power cord only to a 3-contact (two-conductor
+ ground) outlet.
CAUTION
To avoid damage to the product, protect it from
physical shock when transporting and handling. Be
especially careful to avoid physical shock from
dropping.
Do not store or use the product where it could be
exposed to direct sunlight, high temperature or
humidity, or condensation. Under such conditions,
the product may be damaged and insulation may
deteriorate so that it no longer meets
specifications.
To avoid damaging the power cord, grasp the plug,
not the cord, when unplugging the cord from the
power outlet.
This product is not designed to be entirely water- or
dust-proof. Do not use it in an especially dusty
environment, nor where it might be splashed with
liquid. This may cause damage.
