    Before using the manual, take a moment to familiarize yourself with the Table of Contents structure. Set up of an ADCS-601-AF system should not be attempted without using Section 3. All first time ADCS-601- AF users should read Section 4. Section 8 is a quick troubleshooting guide. Use the information in Section 8 to troubleshoot unexpected ADCS-601-AF behavior based on the symptoms of that behavior.

    TRANSITION BETWEEN STANDARDS, ACTIVE AND INACTIVE STANDARD The ADCS-601-AF system is made up of two automated pressure standards with overlapping ranges to cover the full pressure range. An automated PG7601 piston gauge covers the range of 15 to 380 kPa (4.5 to 120 inHg) (see Section 2.2.1). The PG7601 range is extended down to 1 kPa (0.3 inHg) by an FPG8601 force balanced piston gauge with automated...

  • Page 71: Difference Between Requested And Actual Set Pressure

    The majority of the ADCS-601-AF pressure range (15 kPa (4.5 inHg) and up) is covered by an automated PG7601 piston gauge (see Section 2.2.1). The automated mass handling system of the PG7601 can load mass in steps of 0.1 kg.

  • Page 72: Asolute And Gauge Measurement Modes

    DUT and pressure standards are at a common reference pressure. See Section 4.2.3 for additional information on changing measurement modes. There is a well defined order of operation for transitioning the ADCS-601-AF system between measurement modes. The order is controlled by the ADCS Tools software. Mode transitions should only be performed under ADCS Tools control.

    Execution of certain pressure requests could damage the ADCS-601-AF system if the TEST(+) port is open. If nothing is connected to the TEST(+) port, it must be plugged with the plug quick connect stem provided.

  • Page 75: Setting Zero Pressure

    Many devices require pressure exercising prior to validation or calibration. Generally, their exercising can be performed quickly and without precise knowledge of the endpoint pressures. ADCS-601-AF supports a function to allow simple, rapid exercising of the DUT. The exercise function uses the PG7601’s pressure controller alone rather than the pressure standards.

The protection system is based on user rights. ADCS Tools always has an active user. User access can be password protected. User rights can be managed to prevent a user from being able to make changes in specific areas of ADCS Tools.

    4.2.9 PRESSURE LEAK TEST It is good practice to run a leak test on the ADCS-601-AF after performing a setup or maintenance operation that requires pressure fittings to be disconnected. The leak test can quickly determine if the ADCS-601-AF is performing properly. A report detailing the status of the individual portions of the leak test is provided upon test completion.

This avoids requiring separate vacuum facilities and offers the convenience of not needing to disconnect the CDGs electrically.

    RECALIBRATION 7.3.1 OVERVIEW To assure that the ADCS-601-AF operates within pressure measurement uncertainty limits, certain metrology maintenance functions are required. See Section 7.2 for instructions on these procedures. In addition to the metrology maintenance functions, to assure that the pressure values set and measured by the ADCS-601-AF remain within predicted measurement uncertainty levels over time, regular recalibration of certain components is required.

    These values may change from calibration to calibration and the new values must be entered into the ADCS-601-AF system so that they are used in its pressure calculations. The characteristics of a piston-cylinder include many other values but these are constant over time.

  • Page 161: Pg7601, Calibration Of Mass Set

    Piston gauge mass sets are often calibrated in a facility other than that in which the ADCS-601-AF system is used so calibrating the mass set requires removing it from the PG7601 Platform and shipping it. If the mass set and the piston- cylinder module are to be calibrated by the same facility, they are usually shipped together, with the PG7601 Platform if necessary.

    The calibration report lists a value measured by the calibration facility for each mass. These values may change from calibration to calibration and the new values must be entered into the ADCS-601-AF system so that they are used in its pressure calculations.
