NOTE: The Gas Module must be fully warmed up before
performing a gas calibration. For maximum accuracy, a
warm-up time of 30 minutes is recommended.
1. Select Start Calibration and “Yes” within the Gas Module Menu (refer to “Gas Module
Menu” on page 1-182). The menu shown on the next page will appear:
FIGURE 1-80 Start Calibration Menu
2. Select the calibration gas type from the choices, and “Yes” to start calibration.
3. If Mixture has been selected, the following window will appear:
FIGURE 1-81 Calibration Data
4. At the start of the calibration, the Gas Module will zero the gas channels. After a
successful zeroing, the Gas Module will request the calibration gas.
NOTE: If the Gas Module cannot zero, a “zeroing error” will be
displayed and the previous calibration data will be
restored. Repeat the calibration procedure from step 1. If
problems persist, call for service.
5. The message “Feed Calibration Gas” will appear. At this point, attach the calibration
gas canister to the regulator and turn it on. Increasing gas values will appear in the
window as the Gas Module samples the calibration gas.
6. When sampling is complete, a “Continue?” message will appear. If the values are
acceptable, press the SELECT key. If for any reason, it is desired to cancel calibration,
press EXIT to re-install the previous calibration values. The entire calibration must be
accepted as a whole or not at all.
NOTE: To avoid premature emptying of the gas canister, always
remove the regulator at the end of the procedure, prior to
storage.
