Examples
Below are some examples, showing what happens to the output when different values for scaling and calibration
are applied to an InstrumentNet sensor.
Never use equal values in Scale Max or Scale Zero. It will result in an illegal mathematical
operation, divide by zero!
No scaling and no calibration
Output value (1 0 Sensor value) (0 0)
Output value Sensor value
Output is calibrated, 1,5 is added to the input value
Output value (1 0 Sensor value) (0 1,5)
Output value Sensor value 1,5
Output is scaled, the input value is multiplied by 0,7
Output value (0,7 1 Sensor value) (0 0)
Output value Sensor value 0,7
