Adding and Calibrating a Loadcell
This section is meant to guide you through the process of connecting a second
loadcell to your indicator and configuring the loadcell for use in your application.
To connect a second loadcell, disconnect the first and connect the 7-pin connec-
tor from the second to the indicator at the same spot. You need to configure the
FI-127 to use this loadcell correctly by assigning a cell number to it, defining what
type of loadcell it is and several other parameters. Refer to the loadcell menu
shown in Figure 12 while going through the following instructions. These instruc-
tions assume the unit is not sealed.
1. From Display mode, key in '127' and
press and hold the ESCAPE key. . . About is displayed.
2. Repeatedly press the MENU key
until SEtUP is displayed, then press
the ENTER key. . . Units is displayed.
3. Press the MENU key. . . LOACEllS is displayed.
4. Press the ENTER key. . . Cell 1 is displayed in this example. If
you press the MENU key, you will see
the current list of loadcells shows just
Cell 1 and End.
This is the point at which you assign your new loadcell a number. For this example
we'll use Cell 2. You need to insert this cell number into the list.
5. With End displayed, press the +/-
key. Cell 2 is displayed showing that a new
cell has been added to the list.
You now need to define what kind of cell this is.
6. Press the ENTER key. . . CEll tYPE is displayed.
If you look at Figure 12 you will see that the other items in the list with Cell Type
are Polarity, Linearize, Config. and Clone.
7. Press the ENTER key. . . torquE or FOrCE is displayed.
Be sure you perform the procedure
described at right only on a cell you
really want to change.
Print or record your existing calibra-
tion as described on page 24. This
will preserve these values for future
re-entry if necessary.
