PRECAUTIONS FOR USE
This instrument is protected against voltages of not more than
1000V with respect to ground in measurement category III
or 600V in CAT IV between the sensor and the conductor of
which it measures the current.
The protection provided by the instrument may be impaired
if the instrument is used other than as specified by the
manufacturer.
■ Do not exceed the rated maximum voltage and current or
the measurement category.
■ Observe the conditions of use, namely the temperature,
the relative humidity, the altitude, the level of pollution,
and the place.
■ Before each use, check the integrity of the insulation
on the coil, the cords and the housing. Do not use the
instrument if it is open, damaged, or poorly reassembled,
or its accessories if they appear damaged.
■ The sensor must not be applied to or removed from
uninsulated conductors at dangerous voltages.
■ Use personal protection equipment systematically.
■ All troubleshooting and metrological checks must be per-
formed by competent and accredited personnel.
