and the test will fail. The following error message will be displayed:
Configuration Variables Test
A CRC of the configuration variables is computed from the configuration value
stored in NVRAM and compared to the CRC stored in the NVRAM, which was
computed when the configuration variables were set. If the configuration
variables have changed since the calibration values were set or if the CRC
value stored in the NVRAM has changed, the computed CRC will not match the
stored CRC, and the test will fail. The following error message will be displayed:
Protocol Variables Test
A CRC of the protocol variables is computed from the protocol value stored in
NVRAM and compared to the CRC stored in the NVRAM, which was computed
when the protocol variables were set. If the protocol variables have changed
since the protocol values were set, or if the CRC value stored in the NVRAM
has changed, the computed CRC will not match the stored CRC, and the test
will fail.
No error code is associated with a protocol CRC failure. The protocol variables
automatically reset to their default values. (Protocol variables are user
modifiable options that are protocol specific, and are accessed by using the
MODIFY PROGRAM
key during the Application mode.) The following error
CALIBRATION CRC FAILURE
CODE = 7
PLEASE POWER OFF.
CONFIGURATION CRC FAILURE
CODE = 52
PLEASE POWER OFF.
