PV-SCALE - 3 - Scaling of the process controller for selection of the Pt 100
input (PV INPUT PT 100)
The PV-SCALE function specifies the following settings for the Pt 100 signal type:
• The unit of the process actual value.
• Position of the decimal point.
• The values for the lower and upper process actual value.
If the settings for the unit of the process actual value or the position of the decimal point are input or
changed, this setting applies to all scaling values (
PVmin, PVmax, SPmin, SPmax).

lower scaling value for the process actual value
1. select the unit for the temperature
The unit on the display has a dark background. Press the up arrow key (+) to select from the following
units:
°C or °F.
2. input the position of the decimal point
Press the down arrow key (←) to highlight the decimal point with a dark background. Press the up arrow
key (+) to specify the position.
Adjustment range: 1 or 2
3. input the lower scaling value for the process actual value
Press the down arrow key (←) to highlight the individual positions with a dark background. Press the up
arrow key (+) to set the value.
Adjustment range: -200 ... 800
Measurement range of the Pt 100: -20 °C – 220 °C or -4 °F – 428°F
This setting specifies the reference range for the dead band of the process controller as well as for the
analogue feedback of the process actual value (option).
