Precautions For Use; Presentation - Würth Flex 400 Traduction Des Instructions D'origine

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 manu-
facturer.
• 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
performed by competent and accredited personnel.
The Würth Flex is used for RMS measurements of current,
from 20 mA to 400 A.
The sensor takes the form of a flexible coil 17 cm long,
connected by a shielded cord to a small housing containing
the signal processing electronics, supplied by a battery.
The flexibility of the sensors makes it easier to wrap them
round the conductor to be measured, whatever its type
(cable, bar, strand, etc.) and its accessibility. The design of
the snap-action coil opening and closing device allows it to
be handled while wearing protective gloves.
