Adding a Calibration point

Calibration points can be manually added to the Calibration table. The amount of Calibration points that can be stored is determined by the type of speed transducer and method of connection.

  12. Select OK.
  13. Repeat steps 7 to 11 for each Calibration point you want to add.

    The more Calibration points you add the higher the accuracy of Log speed will be.

Note

If the text appears red then the new reading deviates too far from the stored reading. You will need to add a Calibration point closer to the stored reading a try again.
