■
The operator and/or the responsible authority must carefully read and
clearly understand the various precautions to be taken in use. Sound
knowledge and a keen awareness of electrical hazards are essential when

■
If the instrument is used other than as specified, the protection it provides
may be compromised, thereby endangering you.
■
Do not use the instrument on networks of which the voltage or category
exceeds those mentioned.
