WARNING!
Further hazardous area safety instructions:
Observe the operating information and the relevant state regulations
concerning use in hazardous areas (e.g. EN IEC 60079-14).
The model CPH65I0 intrinsically-safe hand-held pressure calibrator has
been designed for use in hazardous areas. In these areas there is the
possibility of inflammable or explosive gases being present.
The model CPH65I0 intrinsically-safe hand-held pressure calibrator has
been designed to be intrinsically safe. This means that connection with
other equipment that is in an intrinsically-safe circuit will not lead to arcs
capable of causing ignition, so long as the parameters are complied with.
WARNING!
Hazardous Areas
A hazardous area, as used in these operating instructions, refers to
an area made hazardous by the potential presence of flammable or
explosive vapours. These areas are also referred to as hazardous
locations.
