Master Mode Analog Setpoint Example
The following example demonstrates Master mode scaling using analog setpoint:
A pump delivers 20.0 gallons per minute when the pump motor rotates
at 1800 RPM. The pump motor is equipped with a 60 tooth ring kit
feedback sensor. The pump will run at 20.0 gallons per minute with an
analog input of 10 volts.
