the contact is opened. At this point, the new calibration values will be recorded before the
instrument returns to SAMPLE mode.
If the AutoCal attribute CALIBRATE is disabled, the instrument will return to SAMPLE mode,
leaving the instrument’s internal calibration variables unchanged.
7.8. Manual Calibration in Multigas Measurement Mode
If the analyzer is being operated in multigas measurement mode, the methods and setups for
performing calibrations are identical to those defined in Sections 7.2 and 7.4 with the two
exceptions
• Some provision must be made for supplying both types of calibrated span gas to the
analyzer. A typical setup for this might be:

Once this selection is made, the calibration procedure continues as previously described. The other
gas may be calibrated by starting over from the main SAMPLE display.
