Pressure Offset

This procedure evacuates the system and zeroes the pressure transducers. This calibration should only be performed by qualified service personnel. In order to perform this procedure, sample tubes must be attached to each port.

  1. Install a blank sample tube or small plug on each applicable port.
  2. Ensure that all applicable transducers are selected, then click Start. Click OK when the process is complete. The current pressure readings and operation status messages display.

 

When the calibration is complete, a confirmation message is displayed with the event log message for the pressure transducer offset calibration. Click OK.
