3-5 VER 12.0 Programming
(Unit with 16 Point Linearization)
Overview:
This Section of the manual provides an outline of
programming procedures for the software version
12.0. Detailed descriptions and programming
instructions for this unit are available in the follow-
ing sections of this manual. Page number refer-
ences are included to help you find related informa-
tion in this manual.
Programming Procedures:
Enter Program Mode - Press the MENU button,
“D”, in the Run Mode.
Choosing a Sub Menu - Once in the Program
Mode, continue pressing the “D” button until the
desired Sub Menu is displayed. Press “ENT” to
enter the selected Sub Menu.
Making a Selection - An arrow, “
↓
”, appearing over
only the “D” button indicates that “D” is used to
change the selection. When an arrow appears
over “B” and “D”, one must be selected.
Entering a Value - The keypad is used to enter a
number. Use the “D” button to enter a decimal.
(Ex: 34.5 would be entered by pressing “3”, “4”,
“D”, and “5”)
Accept a Value or Selection - Press “ENT” to
accept the value and go to next step.
Exit Program Mode - Program or skip each step of
one of the menus to return to the Run Mode.
Pressing “ENT” allows a step to be skipped
without changing its value. (Note: “B” or “D” must
be pressed on the first step in the DEV TYP
menu)
Key to Programming Flow Chart:
■ Display - This box represents the unit's
display. In the Run Mode, the flow rate, the
batch total, or the grand total will be dis-
played.
XX Current Value - The number that is currently
programmed for that step. It must be cleared
(CLR button) before entering a new value.
00 No Value - Indicates that programmed value
for that step has been cleared, and a new
number may be entered.
Keypad - Use the front panel keypad to enter
a value or select a decimal point location for
this step.
3-6 VER 12.0 16 Point Linearization Notes
(See Programming Flow Chart, Page 12)
A K-Factor and a Frequency must be entered for at
least three points on a unit with Linearization.
Linearization K-Factor: The K-Factor for each
Linearization point must be modified to allow for the
display decimal point location chosen in the “DEC
LOC” step of the “DEV TYP” menu. Modify each
K-Factor using the following equation:
DPF - The Decimal Point Factor is a divider to
compensate for the displayed decimal point.
DPF Table
DPF Decimal DPF Decimal
1 XXXXXX. 1000 XXX.XXX
10 XXXXX.X 10000 XX.XXXX
100 XXXX.XX 100000 X.XXXXX
Calculating K-Factors and Frequencies: If a
Linearization table is not available, the K-Factor
and the frequency for each point can be calculated
using the Test Mode on the unit. Refer to Section 7-
3.2, Test Mode Operation and K-Factor Calculation,
on page 37.
Entering K-Factors and Frequencies: Refer to
Section 7-3, Calculating 16 Point K-Factors, on
page 37 and the programming step listing on page
23.
