When an alarm or warning is active, a number (1–8) or "N" shows at the
bottom of the screen. A number shows when a sensor warning, sensor
alarm or set point alarm is active. The number identifies the analyzer that

flashes.

cause the analyzer to go to standby mode because the analyzer is not
able to accurately measure and display sample readings.
• Set Point Alarm Log—contains the set point alarms that have
occurred (maximum of 14). Refer to
