Siemens SIPROCESS GA700 Operating Instructions Manual page 89

Note
ULTRAMAT 7 pressure correction
If you are using the internal atmospheric pressure sensor, make sure that the pressure drop
caused by the piping system at the sample gas outlet does not exceed 10 hPa (large line
diameter, short line length). In analyzer cabinets and analyzer enclosure, you can connect the
pressure transducer to the atmosphere in order to record only the atmospheric pressure change.
Note
CALOMAT 7 pressure correction
With CALOMAT 7, you can implement required pressure correction using an external pressure
sensor.
Note
Using an external pressure sensor
An external pressure sensor can process ambient or sample gas pressure values up to 3 bar
(abs.), regardless of the application.
You can obtain additional information on the use of external pressure sensors from your service
partner: → Technical support (Page 149).
Note
Enable analog and digital outputs
If you subsequently install an option module 2.1, you must enable the analog and digital outputs
using SIMATIC PDM after restarting:
1. Establish a connection between SIMATIC PDM and the analyzer.
You may have to log on at the Expert level.
2. Navigate to: Parameter group overview > Properties > Device
3. For the "Option module 2.1" parameter, set the value "Yes".
4. Transfer the modified parameter assignment to the device.
