MSA Ultima X Series Instruction Manual

Calibration Basics
While the Ultima X Series Gas Monitor is factory-calibrated, it is
good practice to calibrate the unit once it is installed in its final
environmental destination.
As with any type of gas monitor, the only true check of its
performance is to apply gas directly to the sensor. The frequency
of the calibration gas tests depends on the operating time and
chemical exposures of the sensors. New sensors should be
calibrated more often until the calibration records prove sensor
stability. The calibration frequency can then be reduced to the
schedule set by the safety officer or plant manager.
Before calibrating, the Ultima X Series Gas Monitor must be
powered for a minimum of one hour to allow the sensor to settle
into its new environment.
"
CAUTION
Before attempting a calibration, power the unit at least one full
hour.
"
CAUTION
To ensure a fully functional sensor, perform a calibration check
and adjustments at initial start-up and at regular intervals.
Non-combustible Chemicals that Reduce Catalytic Sensor Sensitivity
Catalytic Combustible sensors located in areas where
non-combustible chemicals may leak, particularly ones known
to reduce the sensitivity (see following list) should be calibrated
after such exposures.
• Silanes, Silicates, Silicones and Halides
(compounds containing Fluorine, Chlorine,
Iodine or Bromine)
• TABLE 3-2 in Chapter 3 lists interferants for
electrochemical sensors.
When it is determined that calibration
adjustments are required, the Ultima X Series
Gas Monitor provides a one-man, non-intrusive
method of adjustment at the unit.
To calibrate the unit, one of the following
accessories is necessary:
• Ultima Calibrator P/N 809997 (FIGURE 2-2)
• Ultima Controller P/N 809086 (FIGURE 2-3)
• Optional Push-button Calibration (Appendix A).
