7.4.4 Re-calculating the Calibration Factor
The actual calibration factor can also be determined by a simple calculation
using the actual weight and the displayed weight as follows :
Correct factor = Existing factor x Actual weight
Displayed weight
For example: The existing calibration factor is 1.500. The displayed weight
was 780 kg but the actual weight dispensed was 1000kg.
The correct factor is 1.500 x (1000/780) = 1.923
7.4.5 Adjusting the Calibration Factor
NOTE: The factory default Calibration Factor = 1.000
1. Select Cal Mode 3 by pressing the
button and switching the instrument on
again (fig.6). The instrument defaults to

2. Press the button to select the

The calibration factor is displayed and the
