Figure 2-7. Calibration End Display

• If the calibration output signal is enabled during calibration, it will
be held at the lockout value for two additional minutes after
END is displayed.
• When the span gas is removed from the sensor, the sensor
reading should change to show an ambient condition.
• If a CAL FAULT appears on the display, this indicates:
• An unsuccessful attempt to calibrate the Ultima X
Series Gas Monitor
• The Ultima X Series Gas Monitor is operating with the
calibration parameters defined before the calibration was
attempted.
To extinguish the CAL FAULT flag, a complete calibration
procedure must be performed.
The Ultima X Series Gas Monitor allows automatic zero and span
adjustments within a pre-defined range. It cannot make corrections
outside this range, such as when an empty or wrong cylinder of
gas is applied or failure to begin gas flow within the allotted 30-
second countdown occurs.
14. After a successful calibration, remove the tubing from the Flow
Controller and remove the Flow Controller from the cylinder; return
all items to their appropriate location in the Calibration Kit.
