Example: (386.08 cm) * (0.393701) = (152.00 in) = (12 ft 8 in)
Note: The bottom display of the feet and inches display models does not show decimal
points. While the decimal point may not appear, it is included on the factor programming
steps.
For example: if the PV register data is 0 to 100 in a flowmeter, but a flow rate desired on the
display is 0 to 250 GPM, a factor of 2.5 would be entered. On feet and inches display models,
there is no lower display decimal point. Therefore, a factor decimal point of 1 place is
selected, and a conversion factor value of 25 is entered.
Linear (LINEAR)
Linear scaling is used to convert a linear scale of PV to display value.
Input Values 1 and 2 (INPUT)
Enter the Modbus PV register data for scaling points 1 and 2.
Display Values 1 and 2 (DSP)
Enter the corresponding display values for input points 1 and 2.
For example: If a PV register contains data in terms of tank height in feet for a 100 feet tank,
the display value can be linearly scaled for an input of 0 feet (Input 1) displaying 0 percent
(Display 1), and an input of 100 feet (Input 2) displaying as 100 percent (Display 2).
Not available on Modbus PVs assigned to the feet and inches display of feet and inches
display models.
Multipoint Scaling (MP-SCAL)
This type of scaling is only available for PV1. Multipoint Scaling is used when multiple linear
scaling points are required, such as round horizontal tanks or conical storage silos. Up to 32
linearization points may be entered, with linear scaling between each point.
Not available on Modbus PV1 if assigned to the feet and inches display of feet and inches
display model.
Number of Points (NO PTS)
Enter number of linearization points. The default value is 2 points. For linear inputs
requiring only 2 scale points, use Linear scaling.
