11 Instrument diagnostics
11.1 Error classification
A distinction is made between two error
states:
• active –cause of error is acute
• inactive –cause of error no longer exists
When an error is active, the LED in the DIAG
key lights up red; if there is no active error,
the light is green.
Errors are divided into four error classes
depending on their priority:
11.2 Error list and error log
Error list
The instrument manages up to 30 active
errors in a list. The error with the highest
priority is at the top of the list. When the list
overflows, the error with the lowest priority is
deleted. The error is displayed in plain text; in
addition the error number, date and time of
occurrence.
Use the ↓ and ↑ keys to browse through the
list of entries.
You cannot change or delete the entries in the
error list. If the error is no longer acute, it is
automatically removed to the error log.
Error log
After you press E, you exit the error list and
access the error log.
The error log contains every activation and
deactivation of an alarm with the time and
date in chronological order in a list contained
up to 50 entries. Use the ↓ and ↑ keys to
browse through the list of entries. You cannot
change or delete the entries in the error list. If
the list overflows, the oldest entry is deleted.
After a power failure, only the 10 most recent
entries in the error log are retained.
Press on the E key again to return to the
„Diagnostics“ menu.
