• Example with "Resistance measurement 2" setting
The equation for calculating the scaled process value with the "Sensor type
Resistance measurement 2" setting in standard format with corresponding
variables is:
((Unscaled process value × gain multiplier) / 256) + scaling offset = scaled
process value in Ohm
Example:
((100°Ohm × 384) / 256) + 15 = 165 Ohm
Other example calculations for the "Resistance measurement 2" sensor type in
standard format are available in the table below.
