Parameter setting level
5.3 Input scaling
When using current, voltage or resistance signals as input variables for InP. 1 ,
InP. 2 or/and InP. 3 scaling of input and display values at parameter setting level
is required. Specification of the input value for lower and higher scaling point is
in the relevant electrical unit (mA / V / Ω).

Parameters InL. x , OuL. x , InH. x and OuH. x are only visible if
ConF / InP. x / Corr = 3 is chosen.

In addition to these settings, InL. x and InH. x can be adjusted in the range
(0...20mA / 0...10V / Ω) determined by selection of S. t YP .
a
For using the predetermined scaling with thermocouple and resistance
thermometer (Pt100), the settings for InL. x and OuL. x and for InH. x and
OuH. x must have the same value.

Input scaling changes at calibration level (r page 65) are displayed by input
scaling at parameter setting level. After calibration reset (OFF), the scaling
parameters are reset to default.

In addition to these settings, InL. 2 and InH. 2 can be adjusted in the range
(0...20/ 50mA/Ω) determined by selection of S. t YP.
