Operation
The function can be disabled in this menu, but if the function is
enabled and it is triggered, the main will display the sensor fail message
as well as the system alarm will be triggered.
The threshold value must be selected to properly detect there is no
sensor in the cell block. If the threshold value selected is too low, it may
never trigger due to noise resetting the "Time Remaining" counter and if
value is too high it may set the alarm unnecessarily.
To make sure that the threshold is above electronic noise, select a
value that is above ADC count value shown on this function when no
sensor is installed. Double or tripled the value of ADC count so that
threshold is above noise or electronic drift.
Time Remaining counter remains at 30:00 if ADC count does not
go below the threshold and starts counting down when it does.
False Alarm is still possible with a sensor installed in the analyzer
if a sensor offset is so low that it drops below the threshold value. This
is rare but it can happen. There is no recourse if this is happening other
than to disable the feature as long as sensor installation has been
verified.
