4.3 Automatic Calibration
The Automatic Calibration (ACAL) performs several self-adjustments, as well as a zero calibration, a span
calibration, and tunes the positioners PID gain settings. Enter and start the Automatic Calibration from the
Menu level. From the menu level press the down arrow button until ACAL is shown on the display (ACAL
Routine Shown Below).
4.4 Proceed to Exiting Calibration or Perform Advanced Calibration
At this point the calibration of the positioner is complete. The Automatic Calibration that was performed in
Section 3 is adequate for most applications. If no advanced calibration is required proceed to Section 5 to
exit calibration. If the user requires to use the advanced settings to fine tune the positioner he may proceed
with the remainder of this step and perform adjustments and calibrations in the Manual Calibration Menu
(MCAL). From the menu level press the down arrow button until MCAL is shown on the display (MCAL
Routine shown below).
