6.3 Input scaling
When using current or voltage signals as input variables for InP.1 or InP.2,
scaling of input and display values at parameter setting level is required. Specifi-
cation of the input value for lower and higher scaling point is in the relevant elec-
trical unit (mA / V).

Parameters InL.1 , OuL.1, InH.1 and OuH.1 are only visible if
ConF / InP.1 / Corr = 3 is chosen.
The parameters
InL and InH determine the input range
Example mA:
InL= 4 and InH 0 20 means, the measurement is from 4 to 20 mA.
a
For using the predetermined scaling with thermocouple and resistance
thermometer (Pt100), the settings for
InL.1 and OuL.1 and for InH.1 and
OuH.1 must have the same value.
