Diagnostic Error Codes
Each time you start the AEC-4412B/7412B, the controller performs a
set of diagnostic tests to ensure everything is working properly. This
section provides instructions on how to read the error codes from the
LCD front panel display, descriptions of the error codes, and possible
steps to take to resolve an error.
Reading LCD Panel Error Codes
If you receive an error, the front panel LCD shows a message that
indicates the type of error received and additional information about
the error. The error displayed through the front panel LCD looks sim-
ilar to the following:
Error = 1AD
Var2 = xxx
Variable
type
The two or three digit error code represents the error message. Var2
indicates the item being measured and the xxx indicates the numeric
value of the variable corresponding to the particular error. Error codes
and their corresponding messages and variables can be found in Table
B-2, "Error Code Descriptions," on page B-4.
Using the information found in the table and the example listed
above, error code 1AD means The AEC-4412B chip set had a default
hardware register error. The Var2 represents the Default value and the
xxx would be the actual numeric value of the Default value.
