Associated Publications
The following table lists the Druck publications referenced in this manual:
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.

5.4 PACE Indicator Connection for Input Sensor Calibration
1. Connect the output of the pressure calibration standard to the PACE input port.
Note: For gauge sensor calibration, apply positive and negative gauge pressures to the
PACE input port.
2. To attenuate changes in atmospheric pressure, or changes due to drafts, connect the PACE
reference port to the pressure calibration standard reference port. If a reference connection
is unavailable, fit snubber IO-SNUBBER-1 to the PACE reference port.
5.5 PACE Indicator Connection for Barometric Sensor Calibration
1. Connect the output of the pressure calibration standard to the PACE reference port.
6. Calibration Check
Note: The PACE adds the barometric reading to a gauge range to produce a pseudo-absolute
range (for CM2 and below). For CM3 the PACE adds the barometric reading to an absolute range
to produce a pseudo-gauge range.
For PACE calibration menus, refer to Appendix A
To check the calibration of PACE, proceed as follows:
1. Connect the PACE to the pressure calibration standard. Refer to Section 5.
2. Press Task and select Basic.
INFORMATION For optimum performance, connect the PACE reference port
to the pressure calibration standard. If unavailable, fit PACE snubber
IO-SNUBBER-1 to the PACE reference port.

3. With the pressure calibration standard connected to the correct pressure port, select
Measured Pressure and press Range to select the pressure range to be checked.
4. Barometric pressure can be displayed in the status area for -B variants.
5. Set maximum displayed resolution.
6. Press Measured Pressure/Zero to zero the selected gauge range.
7. On completion of the zero operation, the display shows Zero completed successfully.
8. Adjust calibration pressure to the first pressure value and wait until this pressure, as
displayed on PACE, is stable to less than 5 ppm (0.0005%) for CM2 and below (aim for
1ppm (0.0001%) on CM3). Display filtering may be required.
9. Compare the pressure value on the pressure calibration standard to the value displayed on
the PACE and record the difference.
10. Repeat (8) and (9) for each pressure, as prompted by the PACE.
11. If the recorded difference exceeds the permissible deviation (accuracy) for the selected
range, the calibrator requires a calibration adjustment for that range. Refer to PACE Data
Sheet for permissible precision deviation and accuracy.
Note: If it has been less than 24 hours since calibration, the PACE specification equals the
Data Sheet precision specification with respect to the original pressure calibration standard.
If it has been greater than 24 hours since calibration, the PACE specification is the sum of
the Data Sheet precision and the long term stability specification with respect to the original
pressure calibration standard. It is recommended that an adjustment is performed on a new
instrument and/or if the deviation measured is greater than 70% of the 1-Year uncertainty
specification.
12. Select the next pressure range for a calibration check.
13. After completing all calibration checks, adjust the pressure calibration standard to
atmospheric pressure.
14. Disconnect pressure calibration standard from the output.
15. If no further calibration is required, switch off the PACE.
7. Calibration Adjustment
For PACE calibration menus, refer to Appendix A
To adjust the calibration of PACE, proceed as follows:
1. Connect the PACE to the pressure calibration standard. Refer to Section 5.
Note: Calibration adjustments may be carried out in any order. Three calibration points are
required for gauge sensors. Two calibration points are required for absolute sensors.
2. Select Measured Pressure/Global Set-up/Calibration and enter the Calibration
PIN (4321).
3. Select Sensor Correction.
4. Select the pressure range to be corrected.
5. Select the pressure sensor to be corrected.
6. Select Calibration Adjustment.
7. The display shows the first value to be set on the pressure calibration standard and to press
OK when the applied pressure is stable to less than 5 ppm (0.0005%) for CM2 and below
(aim for 1 ppm (0.0001%) on CM3). Use the numeric keys to enter the precise applied
pressure.
Note: The display also shows throughout this procedure the message Calibrating and the
selected pressure range.

English–PACE Calibration Manual | 11
8. Select Accept to store the first value and the display goes to the next pressure value to be
set.
9. Select Repeat to re-apply the same pressure and Quit Calibration to exit the calibration of
this pressure range.
10. Repeat steps (6) to (8) for the next value.
11. Carry out a calibration check to verify this procedure. Refer to Section 6.
12. After completing the calibration procedures, adjust the pressure calibration standard to
atmospheric pressure. Disconnect the pressure calibration standard from the PACE.
13. If no further calibration is required, switch off the PACE.
8. Calibration Procedure for CM3 8 bar Absolute and
Above Ranges
1. Carry out a calibration check (Section 6 steps (1) to (5) and (8) to (14)) on the Barometer
first. If the recorded difference exceeds the permissible deviation then the Barometer must
be adjusted (see Section 7).
Note: If stability is difficult to maintain then the home screen (showing pressure readings)
can be used with 7 digits. If the number of digits is reduced, then the error due to reduced
resolution must be considered with respect to the error budget.
2. Carry out an atmospheric zero on the CM3 reference sensor as per Section 6 of the user
manual K0443 prior to the calibration check. This will zero the reference sensor against the
barometer to remove any drift.
3. Carry out steps (1) to (5) and (8) to (15) of Section 6 for the reference sensor. Note that the
gauge control sensor does not require calibration on CM3 units.
Note: To enable the barometric reading, select the Status Area > Global Setup > Display > Status
Area > Barometric. It is important to consider that this step is not possible with the barometer
unless the CM3-B option is enabled in the module identity window within the engineering menu
(only accessible by Druck service centers). If this option is not available then skip step (2).
