, 0 to 10 V DC (i.e. 0 to 1000 in xLogic).
Actual value
= (internal value ∙gain) + offset, thus
–30
= (0 ∙A) + B, i.e. offset B = –30
+70
= (1000 ∙A) –30, i.e. gain A = 0.1

2:
A pressure sensor converts a pressure of 1000 mbar into a voltage of 0 V, and a pressure of 5000
mbar into a voltage of 10 V.
Actual value
= (internal value. gain) + offset, thus
1000
= (0·A) + B, i.e. offset B = 1000
5000
=
(
1000 ∙A) +1000, i.e. gain A = 4
