This is a feature provided in the design, to facilitate the user to set calibration factor such that
the calibration accuracy is within specified range. It may so happen that detector to detector
sensitivity may slightly vary & by setting this value suitably one can get desired calibration
accuracy. Range provided is 0.75 to 1.25 for calibration factor.
By default it is set to 1.00 default. If user wants to go through calibration again, after changing the
calibration factor, he may do so. Having set this & upon pressing ‘PROG’ key, the next menu
option that appears is SET UNIT.
