4.3.2 Calibration
The Calibration screen displays the days since the last calibration, and the auto span level. This screen also
allows the user to calibrate the sensor by performing an Auto Zero Calibration and an Auto Span Calibration.
Calibration of the sensor using this feature also notifies the Host that the sensor is in calibration mode.

4.3.2.1 Sensor Calibration using the HRT Bridge
Calibration of a sensor using the HRT Bridge follows the same principle as calibrating the sensor via the
magnetic interface. Since most of the calibration information can be found in the associated sensors manual, it
is important to have the sensor manual on hand when performing sensor calibration.
Each sensor type has different criteria that need to be met before calibration of the sensor should be performed.
Refer to the appropriate sensor manual for specific information on gas to be used, flow rates, interference gas,
cross calibration gas, and other sensor specific criteria.
NOTE: The TP sensor does not perform an Auto Zero function. Although the menu may provide this
option, the test is invalid, and is not performed.
