Warm-up And Fatal Error Diagnostic Tree
(Subsection 3)
This subsection describes the warmup- and fatal-error diagnostic tree.
1.3.1 Warm-Up/Operating Error
1
Examine the log (
LOG/BROWSE
).
QUESTION:
Is the last item in the log an error code that appears
similar to this:
Error code: 000000a0 20000000
?
If Yes:
The instrument has failed after warming up: Go to, 1.3.1.1.
If No:
The instrument has failed to complete warm up: Go to, 1.3.2.
1.3.1.1 Operating Error-Code Interpretation
1
Convert the two 8-character hexadecimal words in the error code into its two
corresponding 32-bit binary words using the chart below.
2
Divide the right-most binary word into 16 fields each containing two adjacent
bits.
3
Divide the 14 right-most bits of the second binary word into seven fields each
containing two adjacent bits.
4
Each of the 23 two-bit fields corresponds to the output of an internal test at
the moment the instrument entered Fatal-Error mode.
A non-zero number in any one of the fields indicates a potential cause of the
shut-down as shown on the following page.
