1.1 International Electrical Symbols
This symbol signifies that the instrument is protected by double or
reinforced insulation.
This symbol on the instrument indicates a WARNING and that the operator
must refer to the user manual for instructions before operating the
instrument. In this manual, the symbol preceding instructions indicates that
if the instructions are not followed, bodily injury, installation/sample and
product damage may result.
Risk of electric shock. The voltage at the parts marked with this symbol may
be dangerous.
This symbol refers to a type A current sensor. This symbol signifies that
application around and removal from HAZARDOUS LIVE conductors is
permitted.
Probe fitted with an electronic output limiter providing protection against
voltage surges caused by the accidental opening of the probe secondary
circuit to 30V max. peak.
In conformity with WEEE 2002/96/EC.
