Calibration Process - GE ADTS 542 Instruction Manual

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 Calibra-
tion check.
: Calibration checks must be performed within the calibration check menu because the main
NOTE
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, hysteresis
and repeatability over the ADTS operating temperature range. Precision does not include errors intro-
duced by the equipment used for calibration of the ADTS or ADTS calibration stability errors as stated
on the ADTS data sheet.
