Calibration
Parameter Structure The Bulletin 900 Controller is correctly calibrated before it is shipped from the
factory, and normally need not be calibrated by the user. If, however, it must
be calibrated by the user, use the parameters for calibrating temperature input
and analog input.
Note: Rockwell Automation cannot ensure the results of calibration by the
user. Also, factory calibration data is overwritten with the user’s settings
and the factory default calibration settings cannot be returned after user
calibration.
• To execute user calibration, enter the password 1201 at the Move to
Calibration function group parameter in the Advanced Setting function
group. The mode will be changed to the calibration mode, and
adj will
be displayed.
• The Move to Calibration function group parameter may not be
displayed when the user is doing the calibration for the first time. If this
happens, configured the Initial/Communications Protect parameter in
the Protect function group to 0 before moving to the Advanced Setting
function group.
• The calibration mode is ended by turning the controller power OFF.
• The parameter calibrations in the calibration mode are structured as
shown in Figure C.1.
