11.6.5 Calibration Expired

During the warm up of the instrument, a check is done to

verify if the calibration date has expired. If the instrument

is configured to pause if calibration is due, the user is

asked to continue or not. If yes is selected, the user can

continue using the instrument as normal. If no is selected,

the user is forced to switch the instrument off and return

the instrument for calibration. The calibration due date is

only displayed during the warm up of the instrument and

there will be no indication during normal operation.
