    This module is in a different housing compared to the regular modules. It is removable by taking off the top cover of the chassis. The POC8 uses the barometric pressure, measured by the barometric module, for pressure mode emulation in the channels. If a barometric module is installed the Pressure Mode button in the Home view (main screen) will become active and, when pressed, will toggle between Abso- lute and Gauge mode (see chapter Home View on page 18).

It prevents in > 90 % efficiency contaminants like any liquids, oil or dirt to enter POC8 when the direction of pressure flow is from device under test (DUT) to POC8 or when the device under test is vented.

  • Page 80: Maintenance

    1. VENT THE SYSTEM by placing the device in vent mode. Then turn off the power. 2. Loosen the five Philips screws on the top cover of the device as seen in picture "Top view of POC8" below and open the top cover to reveal the insides of the chassis (picture "Chassis assembly").

  • Page 81: Troubleshooting

    If faults cannot be corrected locally, immediately take the system off line and protect it from unintentional restarts. Contact Beamex for further in- structions. Servicing of electrical, electronic or pneumatic equipment must be performed by qualified and authorized technical staff, observing all relevant safety regulations.

  • Page 82: Calibration

    The recommended calibration medium is dry nitrogen or clean dry instrument air. A height varia- tion between the standard and the POC8 can cause significant errors. A calculation should be made to compensate for this difference. This compensation can be done as presented in chap- ter Head Pressure on page 80.
