Where:
Example:
1. Show feet to the hundredths (0.00) with 100 pulses per foot:
2. Show feet with 120 pulses per foot: Scale Factor would be 1 / (120 x 1 x 1)
General Rules on Scaling
1. It is recommended that, the scale factor be as close as possible to, but not
2. To double the number of pulses per unit, use totalizer modes direction X2 or
3. A scale factor greater than 1.00000 will cause Totalizer display rounding. In

5. Lowering the scale factor can be accomplished by lowering the totalizer
