1. Introduction
PACE controllers and indicators incorporate a calibration facility. For the PACE to stay within
specification, a calibration check should be carried out at chosen intervals. If the as found
calibration data of the PACE is not within the permissible deviation, carry out a calibration
adjustment.
2. Calibration Status
The
Measured Pressure/Instrument Status
menu displays the calibration status of the
instrument on the front panel screen. The
Calibration History
lists the dates of the stored
calibration corrections.
Note:
The Date and Time must be set correctly in the
Measured Pressure/Global Set-
up/Calibration
menu.
3. Calibration Equipment
The original Druck Calibration Certificate shows the measurement uncertainty of the original
pressure 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
pressure calibration standard.
4. Preliminary Operations
Review and become familiar with the whole procedure before performing a calibration.
Before performing a calibration:
1. Turn the PACE on and allow it to thermally stabilise (for at least 2 hours) in a thermally stable
environment.
2. Carry out a leak test as detailed in PACE User Manual K0443.
5. Notes on Calibration
The pressure calibration standard output port and the PACE reference level must be at the same
level. See illustrations below for PACE reference level. If the pressure calibration standard is not
at the PACE reference level, use height-corrected applied pressure.
