PACE Series Calibration Manual
[EN] English 1 K0450 Revision B
1 Introduction
The PACE controller incorporates a calibration facility; for the PACE to stay accurate, a
calibration check should be carried out at chosen intervals. If the accuracy of the PACE is not
within the permissible deviation, carry out a calibration adjustment.
2 Calibration Status
Using the Measured Pressure/Instrument Status menu, the calibration status of the
calibrator can be displayed on the front panel screen. The status menu includes Calibration
History which gives a list of dates of the stored calibration corrections.
Note: The Date and Time must be set correctly using the Measured Pressure /Global Set-up/
Calibration menu.
3 Calibration Equipment
The original GE Calibration Certificate shows the measurement uncertainty of the original
calibration standard. To preserve uncertainty of the PACE calibration, checks and
adjustments must be performed using a calibrator uncertainty of less than or equal to the
original calibration standard.
4 Preliminary Operations
Review and become familiar with the whole procedure before beginning a calibration
process. Allow at least one hour for the PACE to thermally stabilize in a thermally stable
environment after switching on and before calibration.
Before starting a calibration procedure:
Carry out a leak test as detailed in PACE user manual K0443.
5 Notes on Calibration
The pressure standard output port and the reference
level must be at the correct level or use height-
corrected applied pressure.
To prevent applied calibration pressure “back feed” in
PACE controllers, fit blanking plugs to both positive and
negative supply ports on the manifold.
Set the PACE units of pressure to one of the required units for calibration.
