Setting the Decimal Point (
dEc pt
)
The decimal point may be set with up to five decimal
places or with no decimal point at all. The rate, total,
and grand total decimal points are independent.
The decimal point selection should be made prior to
scaling, calibrating or programming the controller.
Press the Up arrow to move the decimal point one
place to the left. Press the Right arrow to move the
decimal point one place to the right.
Programming the Batch Controller
(
prog
)
The controller may either be scaled (
SCALE
) without
applying an input, calibrated (
Cal
) by applying an
input, or you may use the K-Factor menu to match the
rate/totalizer with a flowmeter’s k-factor (pulse/unit of
measure). The controller comes factory calibrated to
NIST standards, so for initial setup, it is
recommended to use the (
SCALE
) function.
The
Program
menu contains the following menus:
1. Input Calibration
a. Enter K-Factor
b. Scale without a signal source
c.
Calibrate with a signal source
2. Total time base & conversion factor
3. Batch mode
a. Manual batch control
b. Automatic batch control
4. Grand total time base & conversion factor
5. Grand total reset mode
a. Manual reset
b. Automatic reset with time delay
The process inputs may be calibrated or scaled to any
display value within the range of the controller.
Additional parameters, not needed for most
applications, are programmed in the
Advanced
Features
menu; see
Input Calibration Method (
InCAL
)
There are three methods of calibrating (or scaling) the
display to show the correct engineering units.
•
Use the
Factor
menu to enter a K-Factor
•
Use the
Scale
menu to enter the scaling without a
signal source.
•
Use the
Calibrate
menu to apply a signal from a
signal source.
Note: The K-Factor, Scale, and Calibrate functions
are exclusive of each other. The controller uses the
last function programmed. Only one of these methods
can be employed at a time. The Scale and Calibrate
functions can use up to 32 points (default is 2). The
number of points should be set in the Advanced menu
prior to scaling and calibration of the controller.
See Multi-Point Linearization
menu on page
50 for details.
K-Factor Calibration (
Factor
)
The controller may be calibrated using the
K-Factor
function. Most flowmeter manufacturers provide this
information with the device. Enter the
K-Factor
(
Factor
) menu and select the decimal point with
highest resolution possible and program the k-factor
value (
i.e.
pulses/gal). The controller will automatically
calculate the flow rate using the k-factor and the time
base selected.
