This manual contains important information on proper usage of the device.
This manual describes the DMP 303 and DMP 304 pressure transmitters, which are designed for over‑pressure measurement of gases or liquids. It outlines the intended use, safety warnings, and required qualifications for installation and operation.
Key sections cover mechanical mounting, electrical wiring (including pin configurations and calibration signals), initial start‑up procedures, routine maintenance, service/repair instructions, warranty information, and disposal according to EU directives.

The device must be depressurized and current‑free, and installation must be performed by qualified technical personnel who have read the operating manual.
Apply a voltage of about 5 V to pins 80+ and 80‑ while the device is pressure‑less; this adds roughly 12.8 mA, resulting in a total current of about 16.8 mA.
Dispose of the device according to the European Directives 2002/96/EG and 2003/108/EG on waste electrical and electronic equipment; it must not be placed in domestic refuse.
