Example 2: Scaling 0 to 5 V to Percent Full
Input point 6 of the Unit is connected to a 0 to 5 V signal from a level sensor in a
tank. The user is not interested in the actual volume of liquid in the tank, but
rather in the percent full reading for the tank. It has been determined that a 0 V
reading on the sensor indicates the tank is 25% full, and a 5 V reading on the
sensor indicates the tank is 100% full.
To configure the Unit to report the data in percentage full:
1. Set the scaling low and high limits to 25 and 100.
2. Turn ON the scaling enable bit for input point 6.
