4. Design and function

4.6 RS-232 Interface

The CPG1000 has as standard an RS-232 interface. Only the interface converter offered
by WIKA may be used. The serial data transmission can be used for configuration, calibra-
GB
tion and transmission of the instrument's measured values. For detailed information on
the interface and communication refer to chapter "7. CPG1000 Commands for the Serial
Interface".

4.7 Connections

The CPG1000 uses a ¼ NPT male thread connection for its process connection. An
adapter is mounted on a G ½ male thread as standard. Different adapters may be neces-
sary for connection to the pressure reference standard. The hose, lines and fittings etc.
must always be approved, as a minimum, for the working pressure which corresponds to
the pressure of the instrument. In addition, there must be no leaks during the calibration
process. If necessary, seal using teflon tape.
