Scaling and Calibration
It is very important to read the following information, before proceeding to program the controller:
•
There is
no need to recalibrate
the controller when first received from the factory.
•
All inputs are factory calibrated. The calibration equipment used is certified to NIST standards.
•
Use the
Scale
menu to enter the scaling without a signal source.
•
Use the
Calibrate
menu to apply a signal from a calibrator or a flowmeter for the scaling.
Setting the Input Signal (
Input
)
There is a switch, located to the right of the input connector, which must be configured according to the
input level and type. Jumper J4 located inside the controller, behind the input signal connector, is used to
select the excitation voltage (24 V (
Default setting
), 10 V or 5 V) which is supplied to the P+ and P- wiring
terminals.
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.
Setting the Totalizer and Batching Features (
total
)
After the input type is entered, set the
total
parameter to
“
Yes
” to enable batch control (this is set by
default). If the
total
features are disabled, most batching features and functions are hidden from the
menus.
Setting the Input Units or Custom Tags (
units
)
Enter the input unit or custom tag that will be displayed if alternating rate, total, or grand total and units is
selected in the
units
menu, or
d unit
is selected as the line 2 parameter. See the flow chart on page 29
to access the display menu to show the unit or tag on line 2. The engineering units or custom legends can
be set using the following 7-segment character set:
