Functions
6.10 [2.11] Settings > Pressure sensor selection
You can cover a larger sample gas pressure range (max. 3 bar absolute) by connecting an
external absolute pressure sensor. For additional information, refer to the references t the
end of this section.
CALOMAT 7
You can use external pressure sensors to correct the influence of pressure. For additional
information, refer to the references t the end of this section.

Setting instructions

Note
Module-specific setting
The setting of the pressure sensor is specific to the module. Repeat the procedure for
additional modules, if necessary.
Note
Different signal source setting options for CALOMAT 7
The signal source can be set to the "Device-internal" value only when there is an internal
pressure sensor in the device.
In contrast to OXYMAT 7 or ULTRAMAT 7, the value "None" can be set for CALOMAT 7.
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. The following applies before you use an external
pressure sensor:
• Make sure that your device is suitable for using an external pressure sensor in the
corresponding application.
• You can obtain additional information on the use of external pressure sensors from your
service partner: → Technical support (Page 279).
