6.0 HANDLING WARNINGS
When a system warning occurs, a warning message is displayed and the FAULT LED
blinks. A warning indicates that something in the system needs to be checked or
adjusted. Failure by the operator to respond to a warning may result in poor system
performance and/or less accurate data acquisition. Warnings should be taken seriously.
When a warning is displayed, the MSG and CLR buttons will appear on the menu line
(when not in setup mode). Pressing MSG will scroll through the warning messages if
there is more than one. CLR will clear the currently displayed warning message, and if
there are no more warning messages remaining, the MSG and CLR buttons will
disappear and the FAULT LED will be turned OFF. If after pressing CLR, warning
messages still exist, the FAULT LED will continue to blink and the MSG and CLR
buttons will remain on the menu line.
If after clearing a message, the warning condition for that message still exists, the
message will reappear after a period of time which depends on how frequently the
condition is checked by the CPU (usually every few seconds). If a warning message
reappears every time after CLR is pressed, the problem should be solved and the
Analyzer restarted. Some problems may be temporary and may not reappear after CLR
is pressed (e.g. temperature too high, too low, etc.).
To ignore the warning messages and display the test measurement again, simply press
TEST. The warning messages will remain active and may be viewed again by pressing
MSG.
