The ULTIMA X Series Monitor allows automatic zero adjustment only within a pre-
defined range. Outside this range, no corrections can be made, e.g. when an empty
or wrong gas cylinder is connected or the gas flow did not start within the
30 seconds countdown period.
- If only a zero was carried out, the procedure is complete and the user should
return the calibration equipment to the calibration kit.
- If a calibration was carried out, the ULTIMA will continue to the "span" proce-
dure, which is described below.
Span Calibration
During a regular calibration, the ULTIMA® X Series Gas Monitor automatically be-
gins the span countdown after a successful zeroing.
The span countdown is 30 seconds [ Fig. 11].
Fig. 11 Prompt for supplying test gas
(1) Remove test gas cylinder and flow controller from the calibration kit
(2) Attach the flow controller to top of the span gas cylinder.
(3) Push the small end of the tube from the calibration kit over the flow controller
gas outlet.
(4) When using cal-kit 40, push the other end of the tube over the SensorGard in-
let.
During the 30 second countdown, the span procedure can be cancelled
at any time by pointing the Calibrator/Controller at the ULTIMA display
and pressing any key. Alternatively, if the ULTIMA is fitted with a push-
button press and release it.
