Step 7: Saving the calibration information to EEPROM
After completion of step 6, all of the calibration information is in the RAM memory of the
Smart Pro. You must copy this data to the non-volatile EEPROM for long-term storage. On all
system re-boots, the EEPROM data copies into the RAM memory and becomes the current
configuration. Refer to page46 for information concerning the upload and download
configuration program.
