(10) When using a zero gas cylinder, close the valve on the flow regulator and re-
move the tube from the SensorGard.
If CAL FAULT is displayed, this indicates the following:

®
Series Gas Monitor has failed.
- The ULTIMA X

Series Gas Monitor is operating with the calibration parame-
ters, which were defined before beginning the calibration [ chapter 11.3

To remove the CAL FAULT message, a complete successful calibration procedure
must be performed.
If the calibration output signal is enabled during calibration, it will remain
at the SENSOR CAL value for another two minutes after END is dis-
played.
