Change the polarity in ODS/Modal


The polarity indicates the direction to collect the measurement. The measurement direction is usually determined by the construction of the equipment. If you cannot orient the sensor in the positive direction, change the polarity to a negative direction measurement.

You can change the polarity after you collect data for the measurement point.


  1. Activate a job.
  2. From the ODS/Modal main menu, use the arrows or F9 Point Search key to go to the desired measurement direction.
  3. Press F3 Change Sign +/-.
    The Point field changes to display the updated measurement direction.
