Press ENTER again to confirm and store the new calibration factor, or press ESC to return to
the SETUP menu screen.
It is recommended to reset the PART TOTAL to zero before commencing drilling. This will
enable you after drilling an area, to quantify any error in the calibration factor by logging the
theoretical amount of product used against a known amount used (a whole bag for example).
You can then adjust the calibration factor precisely, if necessary (section 2.7.2).
