Do not exceed the rated maximum voltage and current or the measurement

category. Do not use your instrument on networks of which the voltage or category
exceeds those stated.
Observe the conditions of use, namely the temperature, the relative humidity, the

altitude, the level of pollution, and the place.
Use connection accessories of which the overvoltage category and service voltage

are greater than or equal to those of the instrument.
Do not use the instrument if it is open, damaged, or poorly reassembled, or its

accessories if they appear damaged. Before each use, check the integrity of the
insulation on the coil, the cords, and the housing.
The sensor must not be applied to or removed from uninsulated conductors at

dangerous voltages.
If it is not possible to disconnect the installation from any voltage, employ safe

operating procedures and wear suitable protective gear.
All troubleshooting and metrological checks must be done by competent,

accredited personnel.
