4.1

Introduction

For the system to remain accurate, a calibration check should be carried out at regular intervals.
The recommended calibration period is 12 months. If the accuracy of the system is not within the
specification, carry out a calibration adjustment.
4.2

PIN codes and PIN protection

The ADTS contains some PIN protected menus. The following table lists the factory set default PIN
numbers:

Important note
Change these codes to prevent unauthorised access. Unauthorised access to these menus can
make this system inaccurate and could, in control mode, cause excessive rates of pressure
change.
4.3

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,
hysteresis 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.
