Factor
The third way to customize an RTD sensor (not just PRTs but all types of
RTDs) is using the
Factor
. This applies for sensors with the same relative
error throughout the sensor's span, a sensor with an "offset" in its output.
How to Configure a User Sensor using Factor :
Select a standard Sensor Type . Then enter a Factor that offsets the
standard temperature curve. A simple way of doing it is taking a standard
RTD sensor with a 1 ohm resistance @ 0 °C, e.g. Pt1. Then enter the real
resistance @ 0 °C as the Factor .
