The engineering values calculated in this way by the user can be set by means of the following parameters.

S. 3 2
For correct signaling of error state (Lo, Hi), the value
set in S.00 must coincide with limit Lo.S and the
value set in S.32 with limit Hi.S.
- Signals coming from custom thermocouples
An alternate linearization is available only for sensors consisting of custom thermocouples, created by defining engineering
values at three measurement scale points settable with the following parameters:

N.B. The decimal point does not change the
contents of the PV, but only permits its correct
interpretation.
Ex.: if dP.S = 1 and PV = 300, the engineering value
in °C is 30.0.
