If contact closures are used in conjunction with the analyzer's AutoCal (Section 6.9)
feature and the AutoCal attribute CALIBRATE is enabled, the T101 will not re-calibrate
the analyzer until 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.
If the analyzer is being operated in multigas measurement mode, the methods and setups
for performing calibrations are identical to those defined in Sections 6.2 and 6.4 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:
