Post conditions

After a successful manual spool calibration, the calibration counter and bit inverted copy for spool calibration should be
updated as described below:
•
Populate a temporary data sector for "Production/Calibration Flag". Update the Spool dead-band calibration
counters. Increment P3771 from 0 to 1 and increment bit-wise inverted P3772 from 255 to 254 for the displayed
below,
Production/Calibration Flag
Name
Calibration counter - Spool calibration
Bit inverted value for "Calibration counter -
Spool calibration"
Calibration counter - Analogue WAS
calibration
Bit inverted value for "Calibration counter -
Analogue WAS calibration"
Calibration counter - CAN WAS calibration
Bit inverted value for "Calibration counter -
CAN WAS calibration"
Calibration counter - Analogue joystick
Bit inverted value for "Calibration counter -
Analogue joystick"
•
Calculate the sector CRC as CRC-16-CCITT (P3771...P3778) and store (word) at the CRC/Checksum address
(P3789). For example of how to calculate sector CRC, please see paragraph 17.5.2
•
Write data sector "Production/Calibration Flag" to the MAIN-controller
