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.
Scaling the PV Display Values
(
sCale
)
The data that the scanner receives can be scaled to
display in engineering units. Input 1 must be less than
Input 2, Input 2 must be less than Input 3, etc. (known
as monotonic values). Press
Enter
to save the
changes or
Menu
to exit without saving. When the
Linear function is selected for PV1 & PV2, up to 32
points may be programmed to handle non-linear data.
Only two points are available for all other PVs and for
either the Square Root or Programmable Exponent
functions. Round Horizontal Tanks are scaled using
the length and diameter of the tank.
Scale Menu
The display will show
Error
if the scaling or
calibration process is unsuccessful. Undesired
operation may occur if the error is not corrected.
Correct the error by either changing one of the inputs
in question or changing the number of points to
exclude an erroneous input point.
Notes:
1.
For Feet & Inches Display format, the display
values will be in the format
99
FT
11
IN
15
/16th
or 8
th
.
Make the left digit for inches and 16
th
blank
if the value is less than 10. Example:
50 Feet,
9 Inches, and 8/16
will be displayed as
50
FT
_9
IN
_8
16th
instead of
50
FT
09
IN
08
/16th
.
2. Scaling Short and Long input values (input 1,
input 2, etc.) should be done without the decimal
point.
Multi-Point Linearization (
Linear
)
The scanner is set up at the factory for 2-point linear
scaling. Up to 32 linearization points may be selected
for PV1 and PV2. All other PVs have two linearization
points available. See
for details.
