Introduction
The FI-90, a full-function force indicator, is available in four versions:
1) the standard AC powered version
2) an AC lead-acid, rechargeable battery version
3) an alkaline battery version
4) a 12 volt DC version
Operations mode provides gross force and peak force readings and allows
viewing and configuration of one or more of these parameters:
 ID number
 up to two cutoff registers
time
 date
The key board consists of six keys that control all gross and peak force
measuring functions and provide access to configuration and system-test
information. See Figure 1.
A dual function key: UNIT selects the operational unit of
measure; LEFT ARROW enters data.

The method of powering up depends on the type of power supply your
indicator uses. Look at the back panel of your indicator and the four back
panel illustrations below and identify the one that matches your indicator.
Then follow the appropriate power-up instructions on the next page.

10
For the standard AC version (See Figure 2): Plug the power cord into the
back of the indicator and connect the cord with an external AC power source.
For the AC / lead-acid battery version (See Figure 3): The power switch
controls your choice of AC power or internal lead-acid battery power. To use
external AC power, depress the bottom portion of the power switch, and plug
the power cord from an AC power source into the AC receptacle. To use the
internal lead-acid battery, depress the top portion of the power switch.
For the alkaline battery version (See Figure 4): Press the power switch to
the ON position (lower portion depressed).
For the 12-volt DC version (See Figure 5: Press the power switch to the ON
position (lower portion depressed).
Your unit is configured to display gross force or peak force. It may also be
configured to display one or more of the following functions: ID number, one or
two cutoff registers, time, and date. This manual assumes the unit is config-
ured to allow full access to all functions. The following flowchart and instruc-
tion procedure explains how to move around in and use the operations menu.

1. Power up the indicator. . . The FI-90 powers up in the same
mode it was in when power was
removed.
2. Access the gross mode. If the
gross annunciator is not
illuminated, press
GRO / PEAK once. . . The gross annunciator illuminates
(See Figure 2).
3. Zero the FI-90 by pressing
ZERO / CLEAR (Any stable
applied force up to full-rated
capacity may be zeroed off). . . 0 is displayed. Any small changes
in force are zero tracked automati-
cally and the displayed zero is
maintained.
4. Select unit of measure by
pressing UNIT . . . The units annunciator indicates your
selected unit of measure.
5. Apply force . . . The applied gross force is displayed.
This procedure allows the FI-90 to monitor a varying force and hold the peak
value.
1. With the indicator powered up in
the gross mode, zero by pressing
ZER0 / CLEAR and apply force. . . Gross displayed value increases to
reflect increasing live force.
2. Press GRO / PEAK to access
peak-view mode. . . The peak annunciator comes on.
Displayed is the incrementing eak
value. It reflects the live gross force
continuing to increase.
3. Remove force, or await removal of
force. . . The force now displayed is the
retained eak value. Retained peak
is measured precisely at the maxi-
mum load sensed by the indicator
before force is reduced. Retained
peak value stays displayed while the
live gross force drops.

In eak load a lications,
removal of force occurs when
maximum tension or com res-
sion strength of the material or
roduct is met.

Entering or Viewing an ID Number
4. View and, if necessary, record the
retained peak value. Press
PRINT / ELECT to transmit data
to a peripheral deviceprinter,
chart recorder, or computer or
other programmable controllerif
interfaced via the RS232 or 20mA
option.
5. Clear the last retained peak value
by pressing ZERO / CLEAR, and
re-apply force. . . The retained peak value is released
and 0 is momentarily displayed. The
display increments in the peak-view
mode, reflecting increasing live gross
force.
6. You may view increasing force in
the gross mode by pressing
GRO / PEAK. . . The gross annunciator comes on and
gross force is displayed. Important:
The next peak captured (see step 8)
will not be displayed with the FI-90
toggled to gross mode, but the peak
will continue to be tracked and can
only be viewed in the peak-view
mode.
7. As desired, you may again view
your last retained peak (displayed
by step 4) by toggling
GRO /PEAK. This key allows
you to toggle between peak-view
mode and gross mode.
8. Repeat steps 3, 4, and 5 for each
peak force measurement
needed. . . The indicator will capture the new
retained peak when force goes above
the last retained peak, even if it is
not displayed, and you can toggle to
the peak-view mode to view it as
desired.
You may enter an identification number of up to seven digits.
1. While in gross weighing mode,
press MENU repeatedly until. . . ID. is displayed.
2. Press PRINT / ELECT. . . The current identification number is
displayed.

13
3. You now have two choices, A or B:
A. Accept the displayed ID by
pressing either GRO /
PEAK or PRINT / ELECT. . . GRO / PEAK takes you directly
out to the gross mode. PRINT /
ELECT displays ID.
Or
B. Enter a new ID of up to seven
digits. Use the data entry
procedure shown in the
section, Entering Data with
Arrow Keys. Then press
PRINT / ELECT. . . The new ID number is accepted and
ID is displayed.
The arrow keys are used to enter data for the ID number, cutoff numbers,
time, and date. Refer to this section whenever the manual instructs you to
enter data for one of those parameters.
Entering data is all done through a single edit character position on the
display. The UP ARROW key increments the digit displayed in the edit-
character position up to the value needed, and the LEFT ARROW key moves
the configured digits to the left, out of the way, and brings up a new zero digit
in the edit-character position. The FI-90 allows you to enter up to seven
character positions of data.
To teach the procedure, we'll show you how to enter the three-digit ID num-
ber, 603. The same keying principles generically apply to your entry of ID,
cutoffs, time, and date.
1. Starting from a display of the
current identification number (the
outcome of step 2 under Entering
or Viewing an ID Number), press
the UP ARROW key. . . First, a zero is displayed
in the edit character
position, indicated here by
an arrow. Only in the edit-
character position can
you edit the numeric value of a digit
upward or downward.
Entering Data with Arrow Keys
Introduction
ID Number as an
Example
If at any time you enter an
incorrect character, ress
ZERO / CLEAR to backs ace
and delete the wrong character,
then re-key.

14
2. Start with the left-most digit (in
our example, a 6 ). Pressing UP
ARROW one depression for each
whole number, increment the
displayed number up to the
desired value. . .
3. Then press LEFT ARROW to
bump the 6 a single space to the
left and display a 0 in the
edit-character position. . .
4. The 0 in the edit-character position
is acceptable for our example's
second digit, so no depressions of
UP ARROW are required for it.
Instead, press LEFT ARROW
again to bump the 60 a single space
to the left and again display a 0 in
the edit-character position. . .
5. Press UP ARROW, as necessary,
to increment the edit character to
the desired value, a 3 in our 603
example. . . Entry of ID #603 is complete.
A data field of more than the
three digits entered in our
exam le ID number would
require one additional combina-
tion of LEFT ARROW and UP
ARROW keyings for each
additional digit.

15
A setpoint cutoff is a force-load value at which an internal electrical connec-
tion is broken, causing an external relay to de-energize. Additional relay
configurations can turn on or shut off another electrical device.
You may configure the FI-90 to accept either one of two types of cutoff: (1) a
gross-based setpoint or (2) an increment-based setpoint. A gross-based
setpoint is called, simply, a setpoint. With this type of setpoint, activation of
a cutoff is signaled by a specified gross applied force. You specify, through
the front-panel keypad, the gross force-load setpoint that will activate each
cutoff. For example, suppose your first cutoff requires 100 pounds of force,
and your second cutoff requires 200 pounds of force; you would set the first
setpoint at 100 pounds of force and the second setpoint at 300 pounds of
force, because those values will represent gross force load when the cutoffs
activate.
With the increment-based setpoint, activation of a cutoff is signaled by a
specified amount of net force. You tell the indicator the net amount of force
required to activate each of the cutoffs. Suppose your first cutoff requires 100
pounds of force, and your second cutoff requires 100 pounds of force; you
would enter 100 for setpoint #0 and 100 for setpoint #1.
You can view the type of setpoint that has been configured in your indicator
by looking at the cutoff display in the operations menu. A decimal point
following the word cutoff indicates configuration of gross-based setpoints. If
no decimal point appears after cutoff, the FI-90 is configured for increment-
based setpoints.
1. Starting from either gross mode or
peak-view mode, press MENU
twice to access. . . CutOFF.0 The decimal after CutOFF
says this is a gross-based setpoint.
Then press PRINT / ELECT. . . nn.n is displayed. The n 's represent
the current value in register 0 .
Viewing and Entering Setpoints (Cutoffs)
The two set oint registers are
numbered #0 and #1.

16
2. Enter a new setpoint value in
register #0, using the procedure
presented in the section, Entering
Data with Arrow Keys. Before you
enter any numeric values, specify
a negative setpoint, if appropriate
for your application. To display a
negative sign, "-", use
UP ARROW to scroll through all
digits and characters until the
sign is displayed. Then press
LEFT ARROW to place a new
edit character in the edit position.
To display a decimal point in your
setpoint, scroll similarly through
all digits until the decimal is
displayed. Use the arrow keys to
enter all digits of the new
setpoint. When the correct
setpoint is displayed, press
PRINT / ELECT to accept the
value and redisplay. . . CutOFF.0
then press MENU to move to the
next register (register #1). . . CutOFF.1 is displayed (if the
second setpoint has been configured;
if not, you now see the time display).
The 1 now displayed stands for
setpoint register #1.
3. Press PRINT / ELECT. . . nn.n is the current value in register
#1.
4. Enter a new setpoint in cutoff
register #1 (See #2 and Entering
Data with Arrow Keys).
5. Press PRINT / ELECT to
accept the value and redisplay. . . CutOFF.1
then press MENU to see the
clock or GRO / PEAK to go
back to gross or peak-view mode.
