Calibration process
The calibration process is PIN protected. This chapter describes the Ps and Pt sensor calibration.
The Tools , Calibration Sensor menu contains the calibration adjustment as part of the function
Calibration check .
NOTE
: Calibration checks must be performed within the calibration check menu because the main
Ps/Pt measure display screen Pt reading includes an “Auto Zero” correction for any residual offset
error between the Ps and Pt sensors.
Precision
Precision is a term which includes the ADTS measurement system errors of non-linearity, hyster-
esis and repeatability over the ADTS operating temperature range. Precision does not include
errors introduced by the equipment used for calibration of the ADTS or ADTS calibration stability
errors as stated on the ADTS data sheet.
