MSA Ultima - Calibration

"
CAUTION
To ensure a fully functional sensor, perform a calibration
check and adjustments at initial start-up.
After initial start-up, the Ultima Gas Monitor also displays a
calibration flag as a reminder to perform a field calibration
(FIGURE 2-2). While this message is displayed, the Ultima Gas
Monitor is functioning within factory-set calibration parameters.
Once the first successful field calibration is performed, the
calibration flag turns off.
During normal operation, the Ultima Monitor displays the gas
concentration of the surrounding environment. The corresponding
output signal can be transmitted to a controller. For a complete
listing of display and output conditions other than normal
operation, see TABLE 4-1.
NOTE: The catalytic combustible model of the Ultima Gas
Monitor is capable of detecting concentrations of
certain combustible gases above 100% LEL. When
exposed to these concentrations, the Ultima Gas
Monitor will display one of two modes:
