Configuring 4–20 mA input channels 23
Setting sensor scaling
Since this input channel uses the 4–20 loop standard, it is necessary to set the values for the 4 mA and
20 mA currents. You enter these values in the 4 mA value and 20 mA value fields.
For example, a temperature sensor will output a signal from 4-mA to 20mA for a corresponding
temperature range of –50°C to 150°C.
You can enter such values in the Sensor scaling section.

Setting post-processing channel values
With the CoreSense M10, it is possible to add additive and/or multiplicative correction factors to raw
sensor data. In CoreSense M10, multiplicative factors are known as slopes and additive factors, as
offsets.
For example, a slope of 1.1 applied to a temperature of 100 degrees brings the raw sensor measurement
to 110 degrees.
As for offsets, an offset of –5 applied to a temperature of 100 degrees brings the raw sensor
measurement to 95 degrees.
You can enter such values in the Post-processing(opt) section.
