Purpose: Use this application to multiply the weight value by a user-defined factor . Division is
also possible if a factor of less than one is selected . The selected factor is saved to
protected memory .
Example: You want to calculate the weight per unit of a sheet of paper (DIN A4) .
To do so, proceed as follows:
– The weight per unit (e .g ., 80 g/m
2 ) can be determined by dividing the weight by
the surface .
– The surface of a sheet of DIN A4 paper is:
0 .210
+
0 .297 = 0 .06237 m 2 .
– Division by 0 .06237 is equal to multiplication by reciprocal value 1 / 0 .06237,
i .e ., 16 .03335 .
– Set the factor to 16 .03335 in the application .
