pressure transmitter.
Any operation not described in the following instructions must not be car-

ried out.

If a failure cannot be repaired, the transmitter must be switched off. The
operator must then make sure that it is only switched on again after the
failure has been repaired.

Prior to installing, starting and operating a pressure measuring instrument,
the user must ensure that the appropriate instrument has been selected
with regard to scale range and performance and that the wetted parts
material is suitable for the specific measuring conditions of the respective
application.

Serious injuries and/or damage can occur should the relevant regulations
not be observed.

Dangerous pressure media such as oxygen, acetylene, flammable gases
or liquids and toxic gases or liquids as well as instruments for refrigeration
plants or compressors etc. require attention above the standard regula­tions. Here the specific safety codes or regulations must be considered.

Contents

Ramaining pressure medium contained in the pressure element may be
hazardous or toxic. This should be considered when handling and storing

the removed pressure measuring instrument.

Repairs should only be carried out by the manufacturer. All other repairs or
modifications of the transmitter are unauthorized.

Attention

Other important safety guidelines can be found in the different sections of
this instruction manual.
