If there is an error, the “Fault” LED blinks and an error message
blinks. Each alarm condition has a corresponding LED that blinks an
amber color when the readings are outside a specified range or limit.
7.6 Instrument Status Display
After warm-up, the detector enters the Status Display. It automatically
starts testing for errors and goes through a cycle of checking each
alarm condition. If there is no error message or alarm condition, gas
concentration is displayed and LED flashes green.
If there is an error or alarm, a corresponding message shows on the
screen, and the LED indicates different statuses:
