WARNING! Be extremely careful when working with bare con-
ductors or main line carrier! Contact with live conductors will
cause an electric shock!
The BENNING CM 9-2 must be used in electrical circuits of over-
voltage category III with a conductor for a maximum of 600 V
to earth or of overvoltage category IV with a conductor for a
maximum of 300 V to earth only.
Please observe that work on live parts and electrical compo-
nents of all kinds is dangerous! Even low voltages of 30 V AC
and 60 V DC may be dangerous to human life!
Before starting the current clamp multimeter, always check the
device as well as all measuring leads for damages.
If it can be assumed that safe operation is no longer possible, switch the device
off immediately and secure it against unintended operation.
Safe operation can be assumed to be no longer possible, if
- the device exhibit visible damages,
