Setting Up the Process Variables (PVs) (pv setup)
Enter the PV Setup menu to set up all the criteria associated with each enabled PV. Once you have
selected the desired PV, you can select parameters for each. These include tag, units, format, display
decimal point, float decimal point (resolution), and scaling of the input data.
Note: PV1 and PV2 can have multiple points for linearization. Only two points are available for all other
PVs and for either the Square Root or Programmable Exponent functions.

Setting the Display Decimal Point (disp.dp)
Decimal point may be set one to five decimal places or with no decimal point at all. Pressing the Up arrow
moves the decimal point one place to the right until no decimal point is displayed, and then it moves to
the leftmost position. The decimal point is programmable only for the Display Value.
Setting the Float Decimal Point (Flot..dp)
If floating point data type is selected, select the number of decimals to correspond to the expected floating
point data; the numbers to right of the LSD will be ignored by the scanner.
Example:
If you have a number such as 12.3456, you have to tell the scanner how many digits to the right are of
interest to you. In this case selecting 4 places will make use of all the digits. For most applications the
display decimal point will be set accordingly (i.e. 4 places).
If 2 decimal places are selected, the number 12.3456 is displayed as 12.35; notice that the number is
rounded up.
