due to short circuits. If persons unfamiliar with electricity
measuring instrument are to use the
instrument, another person familiar with such instruments
must supervise operations.
Notation
In this manual, the risk seriousness and the hazard levels are
classified as follows.
EN

Safety Symbols
Indicates hazardous high voltage.
Provides warning that negligent safety check or incorrect
operation presents a significant hazard that could result in
electrical shock, burn injury, or even death to the user.
Indicates the prohibited action.
Indicates the compulsory action.
Symbols Affixed to the Device
Indicates cautions and hazards. When the symbol is
printed on the device, refer to a corresponding topic in the

Do not use the device to measure bare conductors.
Doing so may result in a short-circuit or electrical shock.
Make measurements at a location on an insulated wire
that has a suitable amount of insulation for the circuit
voltage.
The maximum measurable current varies with the
frequency, and the current that can be measured
continuously is limited. Operating the device at less than
this limitation is referred to as derating. Do not measure
currents in excess of the derating curve. Doing so may
result in device damage or malfunction, fire, or burns due
to sensor heating.
