Measuring Gross Force
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
GROSS / 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 automatically and the displayed zero is maintained.
4. Select unit of measure by pressing UNITS . . .
5. Apply force . . .
The units annunciator indicates your selected unit of measure.
The applied gross force is displayed.
Measuring Peak Force
In peak load applications, removal of force occurs when maximum tension or compression strength of the material or product is met.
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 GROSS / PEAK to access peak-view mode. . .
The peak annunciator comes on.
Displayed is the incrementing peak 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 peak value . Retained peak is measured precisely at the maximum load sensed by the indicator before force is reduced. Retained peak value stays displayed while the live gross force drops.
11
4. View and, if necessary, record the retained peak value. Press
PRINT / SELECT to transmit data to a peripheral deviceprinter, chart recorder, or computer or other programmable controllerif 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
GROSS / 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
GROSS/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.
Entering or Viewing an ID Number
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 / SELECT . . .
The current identification number is displayed.
12
3. You now have two choices, A or B:
A. Accept the displayed ID by pressing either GROSS /
PEAK or PRINT / SELECT . . .
GROSS / PEAK takes you directly out to the gross mode. PRINT /
SELECT 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 / SELECT . . .
The new ID number is accepted and
ID is displayed.
Entering Data with Arrow Keys
Introduction
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 editcharacter 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.
ID Number as an
Example
If at any time you enter an incorrect character, press
ZERO / CLEAR to backspace and delete the wrong character, then re-key.
To teach the procedure, we'll show you how to enter the three-digit ID number, 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 editcharacter position can you edit the numeric value of a digit upward or downward.
13
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. . .
A data field of more than the three digits entered in our example ID number would require one additional combination of LEFT ARROW and UP
ARROW keyings for each additional digit.
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.

Viewing and Entering Setpoints (Cutoffs)
A setpoint cutoff is a force-load value at which an internal electrical connection 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 incrementbased setpoints.
The two setpoint registers are numbered #0 and #1.
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 / SELECT . . .
nn.n is displayed. The n ' s represent the current value in register 0 .
15
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 / SELECT to accept the value and redisplay. . .
then press MENU to move to the next register (register #1). . .
CutOFF.0
3. Press PRINT / SELECT . . .
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.
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 / SELECT to accept the value and redisplay. . .
CutOFF.1
then press MENU to see the clock or GROSS / PEAK to go back to gross or peak-view mode.
