This manual has user instructions and safety information for the PACE instruments. All personnel must be correctly trained and qualified before they use or do maintenance on the instruments.
This symbol warns the user of the danger of electric shock. Ce symbole alerte l’utilisateur sur le danger de choc électrique. Druck is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back initiative (directive 2012/19/EU). The equipment that you bought has required the extraction and use of natural resources for its production.

Review and understand the whole procedure before doing a calibration. Before doing a calibration: Energize the PACE and allow it to thermally stabilize for at least 2 hours in a thermally stable environment. Do a Leak Test as detailed in PACE User Manual K0443 (PACE Control Module only).
1 Reference Level Figure 2: PACE Control Module Reference Level Set the PACE units of pressure to one of the necessary units for calibration. 5.1 Pressure Connection Overview WARNING Turn off the source pressure(s) and carefully open the pressure lines to atmosphere before disconnecting or connecting the pressure lines.
DO NOT CONNECT TAPERED THREADS DIRECTLY TO THE INDICATOR. Connect NPT tapered threads through a suitable pressure adapter. The PACE has parallel thread pressure connectors. Use only the connector type shown in Table 2. Table 2: PACE Pressure Connector Thread Specification...

Refer to Figure 4 for connection to the PACE pressure connectors. 1 PACE pressure connector. 2 Bonded seal. 3 ISO228/1 G1/8 pressure 4 NPT thread pressure connector. connector. 5 Pressure adapter, see Section 5.1.1. Figure 4: PACE Pressure Connection For pressures less than 100 bar (1450 psi), see alternative sealing method in Figure 5.
This is not normally necessary for pressure ranges of 7 bar and above. Connect the output of the pressure calibration standard to the PACE modules as shown in the diagrams.
Note: For gauge sensor calibration, apply positive and negative gauge pressures to the PACE input port. 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.
5.6 PACE Indicator Connection for Barometric Sensor Calibration This connection also applies to PACE1000 units with IRS3 sensors and the PACE Tallis units fitted with a barometer. Connect the output of the pressure calibration standard to the PACE reference port.
Adjust the applied calibration pressure to the first pressure value and wait until this pressure, displayed on PACE is stable to less than 5 ppm (0.0005%) for CM2 and below (aim for 1 ppm (0.0001%) on CM3). The standard deviation of the measured pressure is shown on the screen in the pressure units to help with measuring the deviation in pressure.
Adjust the applied calibration pressure to the first pressure value and wait until this pressure, shown on PACE, is stable to less than 5 ppm (0.0005%) for CM2 and below (aim for 1 ppm (0.0001%) on CM3). The standard deviation of the measured pressure is shown on the screen (σ) in the pressure units to aid with measuring the deviation in pressure.
Adjust the applied calibration pressure to the first pressure value and wait until this pressure, shown on PACE is stable to less than 5 ppm (0.0005%) for IPS sensors and below (aim for 1 ppm (0.0001%) on IRS3 and TRS3 (Tallis)). The standard deviation of the measured pressure is shown on the screen in the pressure units to help with measuring the deviation in pressure.
Adjust the applied calibration pressure to the first pressure value and wait until this pressure, displayed on PACE, is stable to less than 5 ppm (0.0005%) for IPS sensors and below (aim for 1 ppm (0.0001%) on CM3). The standard deviation of the measured pressure is displayed on the screen in the pressure units to aid with measuring the deviation in pressure.
Note: Zeroing the Reference Sensor is not necessary for calibration adjustment as this is reset automatically during the adjustment process. Do a calibration check (see “Calibration Check B - PACE Indicators” on page 13) on the Barometer first. If the recorded difference is more than the permitted deviation then the Barometer must be adjusted (see “Calibration Adjustment B1 - PACE Indicators”...
