Calibration Due Date

After the span is complete, the following calibration due date screens display before returning to
normal operation.
The number of days that displays in the CAL DUE XXX DAYS screen is the earliest date
(overall of all sensors) a calibration must be performed.

S sensor must be calibrated in 65 days.
If a sensor fails to span successfully and it is past the calibration due date, the following
screens display.
