Dillon FI-127 - Manual (Page 26)

The next Setup submenu is Loadcells. Use this menu, shown in Figure 12 to
linearize and configure each loadcell in your system.
Cell 1 This is the first loadcell in a list of loadcells. Cell 2, Cell 3, etc. are
available by pressing the MENU key if they are configured. To
add loadcells to the system, press the +/- key while End is
displayed. To delete the last loadcell from the list, press ZERO
while that Cell # is displayed. The FI-127 supports up to six
loadcells.
Below are the descriptions of the items available under each
configured loadcell.
Cell Type Choose which type of loadcell you are using: Force or Torque.
Polarity Select the direction of positive measurement:
Regular - selects tension for force and clockwise for torque.
Counter - selects compression for force and counter clockwise
(CCW) for torque.
Bi-dir. - specifies that the loadcell is bidirectional and is used for
measuring force in both tension and compression, or torque in
both CW and CCW directions. This selection enables the +/- key
to change measurement direction while in the display mode.
Linearize
Points Use this submenu to view, edit, add, or delete calibration
points in a list. You may have 2-10 points per loadcell with
a maximum of 35 points among all six available cells.
A 0
A 5000
Examples of the two default calibration points. The
indicator will automatically order the list by increasing
count values. The first point will show A 0. The A stands
for Applied load and the 0 for zero force. Access other
existing points by using the Е
Е Е Е Е or MENU key.
The FI-127 comes from the factory with two calibration
points: 0 and 5000 lbs f. (These force values may differ
depending on your unit of measure.)
Cal.
Counts
Points may be calibrated in two ways: 1) by standard force
calibration or 2) by entering count values. Counts are
calibrated to 5000 lbf at 1 mV/V signal from the factory.
Existing points may be reviewed and modified via the
keyboard.
Delete
You can delete a calibration point using this item.
Deadload Lets you view the count value for the current deadload.
Press the UNITS key to change the display to mV/V.
Display Shows the weight display without having to exit the menus.
An example of what is shown—d 5000. The d indicates a
live display of weight and reminds you that the unit is in
calibration. The value you see depends on the selected unit
of measure, the calibration and the weight applied. The
UNITS key works in this mode
.
Loadcells submenu
Calibration is part of the Linear-
ize process. See the section
titled Adding and Calibrating a
Loadcell for more detailed
instructions on calibrating your
loadcell.
