= -0.55
H = upper value of the measuring range in g/cm
3
L = lower value of the measuring range in g/cm

The same is true if the upper and lower point of the measuring range is to be
changed by different values.
Example:
L
actual
= 1.12 g/cm

L
nominal
= 1.15 g/cm

H
actual
= 1.25 g/cm

H
nominal
= 1.3 g/cm

F =
1.30 g / cm - 1.15 g / cm
1.25 g / cm - 1.12 g / cm
= 1.1538
