Reverse the Direction of Sensor Measurement (SPARKvue)

How do I change the direction of a sensor within SPARKvue? Using the calculator, the direction of a sensor measurement can be changed. This can also be used to add a constant value to the reading to give the output calculation an offset relative to the original sensor readings.
In versions of SPARKvue 4.1 and later, it is possible to change the direction using the instructions in the following video.
