ULTIMA XE/XA Combustible
When the ULTIMA XE monitors the surrounding atmosphere, the measuring gas
reaches the sensor by diffusion. In this case the measuring values are smaller than
the measuring values if the same gas concentration is applied via the SensorGard
during calibration.
If the air speed when monitoring the surrounding atmosphere is higher than 1 m/s,
the deviations of the measuring values are within the limits stated by
EN 60079-29-1:2007.
If the air speed is lower than 1 m/s, the limits stated by EN 60079-29-1:2007 will
only be met, if the SensorGard is removed after calibration.
The difference in air pressure between diffusion operation and calibration shall not
be greater than 10 kPa.
5.2 Initial Calibration
When a new sensor is placed in the ULTIMA Gas Monitor, an INITIAL Calibration
must be performed. This procedure enables the unit to gather data about the sensor
to make accurate decisions for the CHANGE SENSOR function and the CAL
