Your FI-127 will probably be ready to use when you receive it from your Dillon
distributor. Connect the loadcell to the 7-pin connector on the back of the unit.
Connect your RS-232 communication equipment to the other connector on back
of the FI-127. Power up your peripheral equipment and plug in the FI-127 to an
appropriate grounded power source.

The indicator will power up in Display mode with annunciators lit for your
application. From the factory, the default annunciators which are lit are Force,
Tension and lb F. The center of zero (COZ) annunciator should also be lit. If the
display does not show 0 or the COZ annunciator is not lit, press the ZERO key.

Your unit is now ready for use in your force measurement application. If you want
to add a loadcell, see the section Adding a Loadcell later in this manual.

With the indicator powered up,

select the unit of measure you

want to use by pressing the

UNITS key. . .

The proper annunciator will light.

Press the ZERO key if the display

does not show 0 and apply force

to the loadcell. . .

The force will be displayed in the unit

of measure you have chosen. The type

of force, tension or compression, will

be indicated by the annunciators under

the display. The motion annunciator

will be lit while the indicator detects

motion.

If you are running a test where

First Peak and Peak readings are

important to you, you can see

those values by pressing the

SELECT key. The value on the

display will correspond to the

annunciated item on the left side

of the display panel. See the First

Peak definition at left.

After you have seen the peak

values, you can reset them by

removing the force from the load-

cell and pressing the PEAK

RESET key.

Repeat steps 2-4 for the other

force measurements you want to

make.

Performing a Force
Measurement

First Peak
First peak is defined as an applied
force, followed by a drop in force of
at least x% of full capacity followed
by an ultimate peak in force. x is
called the capture percentage. You
can set this percentage via the front
panel. Instructions can be found in
the section Using the Service
Menu. See the graphed example in
Figure 2.
