PASS

No Failure

Working calibration checksum passed.

FAIL

The working calibration
constants in the controller
are in error.

1.  If the controller has not been field

calibrated, see Section 3 -
Configuration and change the input to
a different type. Enter it, loop through
the status tests, then return the input
type to the original one.

2.  If the controller has been field

calibrated, recalibrate the controller.

Factory

calibration test

PASS

No Failure

Factory calibration cyclic redundancy test
passed

FAIL

Factory set input constants
have been changed due to
the change in input type.

1.  Cycle through Status to clear the error.

2.  Check the calibration. Make sure 0 %

and 100 % are correct values.

3.  Recalibrate if step 1 is unsatisfactory.
