SYSTEM ERROR INDICATOR
This LED is lit when a system error has oc-
curred. If the situation persists for more than
a few samples, the operator should notify
maintenance personnel for investigation of the
problem. When the meter is in system error
mode, the user can directly access the diag-
nostic code that indicates the source of error. The analyzer
continues to perform the sampling operations during an alarm
condition.
