4.2.3.4 User scaling
User scaling 4- ][Funktionsbeschreibung_BA_Konfig Skalier Anwend Aus
User scaling is an additional scaling level prior to manufacturer scaling.
You can use this scaling to correct local influences. The function is the
same as that of manufacturer scaling:
y = (a
2
/ 256
D
* x) + b
2
or
y = (a
2
/ 100
H
* x) + b
2
a
2
= Amplification factor * 256
D
User scaling is deactivated in the default setting. The default value for
offset is 0. The default value for gain is 256
D
(100
H
). That corresponds
to amplification factor 1.
