Application
The SCALER point allows you to perform simple math functions such as conversion of units. The
SCALER point takes the value from user-specified database references, multiplies each by a
constant and adds the three product terms. A constant K may also be factored in. The SCALER
point works in conjunction with parameters that are in floating point format.
