Front Panel
The FI-127's front panel consists of 24 keys and fourteen annunciators.
Keys
Standard Instrument Keys
Function Keys
Figure 1
FI-127 Front Panel
The FI-127's keys are divided into four primary groups:
Standard Instrument Keys These yellow keys are common to a majority of
applications and include SELECT, PEAK RESET, DATA SEND, ZERO, and UNITS.
The SELECT and UNITS keys are placed next to the annunciators they affect.
SELECT Use to switch between force, peak ad first peak display modes.
SELECT can also be used to accept a current selection and
return to weigh mode from within any menu.
PEAK RESET Use to reset all peak and first peak values. This key may also be
used to capture the current measurement as an entered value
during data entry.
DATA SEND Use to initiate one or more serial outputs.
ZERO Zeros the scale in the display mode. Also clears values in
numeric entry.
UNITS Switches the units of measure in the display mode. Up to three
units of measure are selectable.
Function Keys These oval keys along the right side of the display face are
configurable and are labeled F1, F2, and F3. The default configurations for these
keys are:
F1 Allows load cell selection
F2 Allows entry of ID number
F3 Allows access to cutoff registers.

Page 7
Keypad Keys
Keypad Keys These are the twelve square keys which support numeric entry.
The keyboard keys are labelled 0-9, plus/minus (+/-), and decimal point (.) and are
located near the center of the display face.
+/- This key is used to change the sign of a numeric entry, enter a dash in ID
entry, and insert when editing lists. This key also initiates numeric entry,
except in display mode where it serves to toggle between tension and
compression for bidirectional cells. Toggling between tension and compression resets peak, first peak and break detect; unfreezes the force display; and
halts data capture.
Directional Keys
Directional Keys The directional keys are used to navigate through the FI-127's
menus. These keys are labeled ESCAPE (up), ENTER (down),
MENU (right) and are positioned in a compass-like cluster on the display face.
These directional keys are denoted by the small transparent arrows located next
to them. ESCAPE, ENTER, and
ESCAPE Exits a menu parameter without saving any changes. This key moves
up within a menu. In display mode, ESCAPE "unfreezes" the force
display.
ENTER Used to end digit entry, accept a change made, or select an item
from a function list. ENTER moves down within a menu. When in
display mode, ENTER "unfreezes" the force display.

Setting Up Your FI-127
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.
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.
1. With the indicator powered up,
select the unit of measure you
want to use by pressing the
UNITS key. . . The proper annunciator will light.
2. 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.
3. 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.
4. After you have seen the peak
values, you can reset them by
removing the force from the loadcell and pressing the PEAK
RESET key.
5. Repeat steps 2-4 for the other
force measurements you want to
make.

F3 Key
Cutoff Register
A cutoff register is a force value you
enter into memory (register) which
the indicator uses to control outputs.
There are 10 cutoff registers in the
FI-127. You can set ten different
force values which the indicator will
use to trigger outputs.
When activated (force on the
loadcell is less than the force in the
cutoff registers), these cutoffs are all
on at the same time. Each cutoff will
deactivate as soon as the force on
the loadcell matches the value in
each cutoff register.
When the force is equal to or
greater than positive register values,
or more negative than negative
register values, the corresponding
output is disabled.
When the force is less than the
positive register values, or less
negative than negative register
values, the corresponding output is
enabled.
The F3 key is used to view and change cutoff registers. You can view cutoff
registers by two methods:
Method A:
1. Press the F3 key. . . 1 xx is displayed. The number 1
stands for cutoff register #1 and xx is
the current value in register 1.
2. Continue pressing F3 or MENU
to scroll forward or
backward through the remaining
cutoff registers.
Method B:
1. If you know which cutoff register
you wish to view, press the
number of that register, then press
F3. That particular cutoff register is
displayed.
To change a cutoff value, display the register you want to change then:
1. Key in a new value with the
numeric keypad. Use the +/- key to
change the sign of the value.
Press the ENTER key to accept
the new value and return to
Display mode
or
press the F3 key to accept the new
value and move to the next register.

corresponds to the Cell Type.
Config. This submenu contains force measurement related parameters.
Capacity Use this to see or edit the capacity. The UNITS key
works during this display. 5000 lb f is the default value.
Division This selection allows you to view and edit the division size
of the enabled units of measure. You can enter any
division size. The indicator will use the closest division size
for each enabled unit of measure.
You can view the division in other units of measure by
pressing the UNITS key. The number is stored in the
resolution you enter but is displayed in the closest valid
division size. Any additional resolution is used in calculating division size in the other units of measure.
Zero Use this menu item to set zero related options. Zero
range is specified as a percent of capacity referenced from
the deadload. There are two items in the submenu:
-Range and Range.
-Range - Use this to set the negative range (below
reference zero) within which the unit may be zeroed. 2%
is the default value.
28
Range - Use this to set the positive range (above reference zero) within which the unit may be zeroed. 2% is the
default value.
Page 29
Bust Use this to enter a break percentage. Break percentage is
the drop in force which the indicator will interpret as a
break detection. This is entered as percentage of full
capacity. 10% is the default value. The output signal is
asserted when a break is detected and switches to the
inactive state whenever you perform a zero or peak reset.
Capture Use this to enter a capture percentage. Capture percent-
age is drop in force occurring before a rebound in force to
an ultimate peak of force. This capture percentage is given
as a percentage of full capacity. See Figure 2 for an
illustration.
Stable Use this menu item to set the motion detection param-
eters. There are three items in the submenu: Range,
Delay and Display.
Range Use this to specify the number of ±divisions for
the motion window. Default is 1.0 division.
Delay Use this to specify the number of seconds
during which the weight must be within range (described
above) before a no-motion condition is displayed. Default
value is 0.4 seconds.
Display Choose ON to if you want the display on while
the indicator senses scale motion. Choose OFF to blank
the display while there is scale motion. Default is ON.
Update Use this to set the display update rate from these choices:
1 One update per second.
2 Two updates per second
5 Five updates per second
10 Ten updates per second.
29
Page 30
Average Use this to configure the number of intervals to average
for each force display. This can be entered in one of two
methods: x disp. or x a-ds. Press the UNITS key to
switch back and forth between the two choices.
The suggested method of setting the average is by picking
a value for x disp. Doing this insures that a multiple of the
display rate is always being averaged. This results in a
steadier weight display.
Use x a-ds if you need an exact number of A-D conversions for your particular situation.
Changing the update rate changes
the x disp. or x a-ds value based on
the new update rate.
Harmonizer® filter is used only if the
average value will not filter out the
vibration by itself. See Tips on
setting up and using the
Harmonizer filtering in Appendix
C.
Throughout the calibration process
values will change as you press the
UNITS key to change the unit of
measure.
☞
x disp. - 1 disp. is the default display when you access this
item. x is the number of display interval(s) over which the
data is internally averaged prior to being displayed.
The number of A-Ds averaged is based on the display
update rate you set under the Update menu item. Default
is 1 disp.
x a-ds - x is the number of a-d conversions to average for
each display.
The A-D weight conversion happens 60 times per second
in this indicator. Average is the number of conversions
you want to average for the weight that is displayed.
Default is 12 a-ds when Update is at default of 5 and x
disp. is at default value of 1.
Filter Use this menu item to configure the Harmonizer filter
settings. Constant and Threshld are the two items you
can configure in this submenu.
Constant - This number represents the amount of
filtering. Choose a setting between 1 and 10. Choose 1 for
the least amount of filtering but the fastest response.
Choose 10 for the most filtering but the slowest response. Choose Off to disable the Harmonizer functions
and default to the lowest filtering.
Threshld - This is the window, in the current unit of
measure, within which weight changes are altered according to the constant. 0.0 is the default value. You should set
the threshold value between 130 and 150% of the total
weight oscillations that need to be suppressed. If weight
changes are +20 lbs and -10 lbs, set this value to 130 to
150% of 30 lbs.

When using overload or over
capacity alone, set the other menu
item to its maximum value to disable
any conflicts.
Over This submenu lets you setup the overload and capacity
setting which cause the O. load error message.
Overload - This value is expressed as a percent of
capacity referenced from the deadload determined by
calibration. Overload is restricted to 200% or lower. 105%
is the default value.
Over Cap. - This value expressed as a number of divisions
over the capacity referenced from the zero value. A value
of 9 satisfies UK requirements. Configurable from 0 to
999999 divisions. Default is 9 divisions.
Abuse Use this to set the percent of capacity at which an abuse
count will be incremented.
Clone Use this to initialize a the currently selected loadcell with
the same values of another loadcell. Select the number
loadcell you want to clone. If an invalid value for a loadcell
is selected, Error is displayed.

ASCII Under this menu item are Labels and Strings. Following
the explanation of these two items are instructions for
customizing the labels and strings.
Labels are short ASCII strings predefined at the factory.
When information is sent to a serial port and the layout
calls for one of the preset labels, the associated ASCII
string is sent. Following is a list of the label names and the
character called out by the associated ASCII string:

Top = P (for Peak)
First = I (for Initial)
Tension = T
'Press = C (for Compression)
C.W. = CW (for Clockwise)
C.C.W. = CCW (for Counter ClockWise)
Id = ID
Strings are groups of ASCII characters. You configure the
indicator to call for these strings in the Layout portion of
the menu. There are five predefined strings and ten other
strings you can modify to suit your needs. The five default
strings are:
Ascii 1: Dillon FI-127<cr><lf><End>
Ascii 2: Loadcell <End>
Ascii 3: Peak: <End>
Ascii 4: 1st Peak: <End>
Ascii 5: Average: <End>
35
Page 36
Instructions for working with strings:
An ASCII character is any number between 0 and 255,
inclusive. See Appendix A for a complete list of ASCII
characters used with the FI-127. To repeat any ASCII
character without entering it multiple times, enter the
number then a decimal, then the number of repetitions
you want. For example, an entry of 32.5 specifies that a
space character is to be transmitted five times. If no
decimal is entered, the indicator will send one character.
To insert a character at the end of the string, just press
ENTER while the indicator displays End. To insert a
character before the current character, press the +/- key.
To move back and forth along the string press the
MENU keys. To delete the current character press
ZERO.
Layouts The FI-127 has 14 default print layouts (max. 15) (see
Appendix B: Default Layouts and Examples). The display
shows LAy. nn, with nn being the identifying number of
that layout.
Each layout consists of one or more of the print items in
Table 1 below. Some items have a selectable variable. To
see this variable, press the ENTER key twice while the
item is displayed, key in a value or press the

D.C. Int. Transmits the data capture interval in nnnn format, right
justified with leading zero suppression.
D.C. Hour Transmits the data capture start time.
D.C. Day Transmits the data capture start date.
nn By D.C. Specifies that Layout nn is to be used for every point captured,
in ascending order. This allows you to generate data capture
reports.
End Specifies the end of the layout. Does not transmit anything.
* denotes items that require detailed information. For example: if “LABEL” is
inserted within a layout, you must specify the label to be printed; if “SP” is
inserted, you must specify the number of spaces to be transmitted.
Groups A group defines which ports will print which layouts. A
total of nine groups is available. Six are set up with
defaults. See the list below. Within each group, up to
three ports can output layouts. Port 1 is standard; ports 2
& 3 are offered only if additional serial boards are installed.
Each port is then assigned a layout to print.

Broadcast Enables or disables continuous send. To enable continuous
send, a group number must be entered under GrouP. This
number defines the group to be activated at each display
update.
Autosend Enables or disables autosend. To enable auto send, a
group number must be entered under GrouP. This
number defines the group to be printed each time weight
stabilizes above 1% capacity. The weight must fall below
1% capacity for the indicator to initiate another print.
Choose Save so information is saved in the database
rather than outputting to the serial port. If the database is
full, the data cannot be stored and the autosend trigger is
ignored.

Items in the
Two internal counters record changes to items in the Setup menu. View these
counters under AUDIT in the Service menu (Figure 6). These counters cannot be
reset and thus can be used by auditors or inspectors to check if changes have been
made. One counter is for scale calibration items and the other for configuration
items. The level of protection is set in the Seal submenu.
Setup menu (Figure 10) can be protected from unrecorded changes.
Code No. This item allows you to enter a personalized security code
number. Digits are not shown on the display as you key
them in, so the display prompts you to enter the code
number twice.
All & Phys. The two parameters in the SEAL menu are All and Phys.
Below are explanations of the choices you can make.
All set to Yes - Any time you access the setup menu
and change any item in Table 2, the
appropriate counter increments one
count. Changing multiple items on one
visit to the menu increments the
counter only one count. It's the
number of visits with changes that are
counted, not the number of changes
per visit.
If Phys. is set to No, you can still
press the internal switch and have
instant setup menu access and
editing privileges.
All set to No - With this setting the calibration
internal counter will increment when
you access the setup menu and change
any calibration item in Table 2. The
internal configuration counter will
increment only if you change one of
the configuration items in bold print
from Table 2.
Phys. set to Yes - If Phys. is set to Yes, you must
remove the physical seal (rear sealing
plug) of the FI-127 to access an
internal switch. When you press this
switch you have full editing privileges
and the display shows the first item in
the Service menu, About, without the
need to enter the password.
If you enter the Service menu using
the password and not the internal
switch, you can change only the
configuration items in Table 2 that are
in normal, not bold, print.
Phys. set to No - If Phys. is set to no, correct password
entry is the only way to have editing
privileges of all the items in Table 2
without breaking the physical seal. See
note to left.
If the password is not entered correctly, the setup menu items can be
viewed but not edited.

Adding and Calibrating a Loadcell
Adding a Loadcell
Be sure you perform the procedure
described at right only on a cell you
really want to change.
Print or record your existing calibration as described on page 24. This
will preserve these values for future
re-entry if necessary.
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 connector 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 instructions 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.
48

8. Use the MENU key to toggle
between these two choices. If you
are connecting a torque loadcell,
have torquE displayed when your
press ENTER. If you are
connecting a force loadcell, have
FOrCE displayed when you press
the ENTER key. . . CEll tYPE is displayed. The cell type is
now set and you can move on to the
next item in the list, Polarity.
Now that you have the hang of getting around in this menu and setting the
parameters, use the same method to set the polarity of your loadcell. After
polarity comes Linearization. This important process is explained in detail in the
next section.
Calibrating a Loadcell
Overview
This section gives you more detailed instructions on calibrating your loadcell.
Calibration is part of the menu titled linEAriZE. Refer to Figure 12 as you work
through this section.
Linearization is the process of making the indicator display the correct force along
the entire range of the loadcell's capacity. To linearize a loadcell you associate a
specific force to a specific point on a line of increasing force. See Figure 21.
Figure 21
Linearization illustration
49
Page 50
The Linearize menu provides you with two existing test points, 0 and 5000. You
can insert up to eight more test points for a total of ten. In the following step by
step instructions you will apply the appropriate test force for each test point and
press ENTER to assign the applied force to that point. You will repeat this until
all points are calibrated.
Step by Step
As you add points, the list is placed
in numerical order automatically by
the indicator.
The steps below use the defaults shown in Figure 12. Your system may be configured differently and will look different than this specific example, but this should
give you the idea of how the process works so you can use it to configure your
indicator.
1. With linEAriZE displayed, press the
ENTER key. . . PointS is displayed.
2. Press ENTER. . . A 0 is displayed. This is the zero
calibration point.
You can calibrate this point now or add/delete points. Steps three through five
show how to add a test point and steps 6 through 9 show how to calibrate a
point.
Adding or deleting a test point:
3. With A 0 displayed, press
MENU to see the other existing
test point. . . A 5000 is displayed. This is the second
default test point.
4. With any test point displayed,
press ZERO key to delete the
point. . . The next point in the list is displayed.
or
press the +/- key to insert a
point. . . A _ is displayed.
50
5. Key in the value for the new test
point and press ENTER. . . CAL. is displayed. Continue to the next
step to calibrate or press ESCAPE to
go back to the point display.
Calibrating a point:
6. With the test point you want to
calibrate displayed, press
ENTER. . . CAL. is displayed. You can calibrate this
point using step 7 or press the MENU
key to enter a specific count value. This
is an alternate method of calibrating
Page 51
points.
From the factory 0 counts = 0 force
and 1 mV/V = 5000 lbs force.
7. Apply the test force for this point
to the loadcell and press ENTER
to calibrate this point. . . bUSY is displayed while obtaining a
stable value. Pressing ENTER while
bUSY is displayed causes the current
average to be taken immediately instead
of waiting for a stable value. Pressing
any other key while bUSY is displayed
will abort the calibration step being
performed and the display returns to
the previous display.
When a stable value is obtained d n is
displayed. This is a live display of force.
The d is to remind you that this is not
the normal display mode and the n is
the force on the loadcell.
To exit back to Display mode, press
the SELECT key and save changes
as needed by pressing ENTER or
SELECT with SAVE? displayed.
To exit without saving changes, press
ÅÅ
Å or MENU until No Save
ÅÅ
appears then press ENTER or
SELECT.
8. Press ENTER to return to the
point display. This point is now calibrated.
9. Repeat steps 6-8 for all the points
you want to calibrate. Remember, you must press the MENU
key to move to the second calibration
point. A 5000 is the default.
Finish setting up your loadcell by completing the CONFIG. and CLONE parts of
the menu shown in Figure 12. Use Clone to configure a loadcell identically to an
existing loadcell. Just enter the correct loadcell number you want to clone.
After you complete these selections your loadcell will now be remembered as Cell
2. You can now switch back and forth between the two loadcells by connecting
the one you want to the indicator and selecting Cell 1 or Cell 2 using the F1 key.

Freeze Force Function
Control
Display
Keypad
Whenever a ‘freeze’ action (assigned to hardware input and/or a serial input
character) is executed, the current a-d value (at the output of the low-pass filter)
is captured, or “frozen”. An ‘unfreeze’ action (assigned to hardware and/or a serial
input character) may be used to “unfreeze” the force value. These actions can only
be executed while the instrument is in the display mode — they are ignored at any
other time.
Whenever Force is selected in the display mode, the frozen value is displayed
(linearized and scaled as a normal force measurement) with the letter “F” as a
prefix, in the form “F 1234.5”. (If data capture is in progress, “b” is displayed
instead of “F” or “C”). The ‘Force’ annunciator, ‘Tension’ or ‘Compress’ and a
unit of measure annunciator are active to properly identify the frozen force value.
The front panel keys perform their usual functions with the following modifications:
ESCAPE and ENTER immediately “unfreeze” the force value.
Outputs
ZERO and PEAK RESET also unfreeze the force value in addition to their usual
functions.
Analog output, BCD output, cutoffs, bounds checking, printed force all use the live
force, even if the force display has been frozen. The Disp. layout item provides a
way to print frozen force if required. In this case, the force output is prefixed
with an “F”.

Data Capture
Control
Display
Keypad
Whenever a ‘Capture’ action (assigned to hardware input and/or a serial input
character and/or Capture Start in the user menu) is executed, data capture is
initiated. The current time and date are saved, and points are stored in memory at
the configured capture rate. A ‘Stop Cap.’ action (assigned to hardware and/or a
serial input character and/or Capture Stop in the user menu) may be used to halt
the data capture. Otherwise, it continues until the specified number of points have
been stored or until stopped as described below.
While data capture is in progress, the first character of the display, in Force, Peak
or 1st Peak display modes, is set to display “C” (If Frozen Force is displayed, a “b”
is displayed instead of “C” or “F”. (Serial output formatting is unaffected by this
status indication.)
The front panel keys perform their usual functions with the following modifications:
ZERO and PEAK RESET also stop data capture in addition to their usual
functions.
ESCAPE and ENTER do not stop data capture. They are available to “unfreeze”
the force display without interfering with the data capture function.
Outputs
Notes
Entering the service menus halts data capture.
Changing loadcell selection (under the F1 key) halts data capture and deletes
points.
Start and Stop are available under Capture in the user menu.
The menus under Capture in the user menu provide access to display, send and
delete captured points and related statistical data.
All outputs are unaffected by data capture.
The stored data are deleted in the following circumstances: via the Delete menus
under Capture in the user menu, whenever the Setup menus are entered, whenever Reset Setup is performed.
Hardware input and serial input can start and stop the data capture only while the
instrument is in the display mode.
Low Voltage, Load Cell Error or Lockup all cause the Data Capture to be halted.
Overranged values are still stored, but displayed and printed in the same manner
as other overranged values.
Data capture is disabled if the Capture Interval is set to zero or if Capture Points
is set to zero.

Appendix C: Tips on setting up and using the Harmonizer
To find the best settings for your filter needs, follow the steps listed below.
1. What to Do: Determine the amount of positive and negative force
exerted by the vibration on the scale.
How to Do It: Set Threshld to 0.0, Constant to OFF, and Average to
1.0 A-Ds. Return to Display mode and observe the force swings. Record
the difference between the highest and lowest displayed force values.
Add 30 to 50% to this value. This is a good starting value for the
Threshld setting. Do not set your indicator to this value until told to in
step 7.
2. Setting the Average to higher values increases the filtering effect.
What to Do: Set Threshld to 0.0, Constant to OFF and Average to
15.0 A-Ds. Check the stability of the loadcell.
How to Do It: Save changes and exit to Display mode. Observe the
Center of Zero light. If it is on all the time your loadcell is stable within
¼ division. If the Center of Zero light blinks more filtering is required.
Go to step 3.
®
3. Repeat step 2 but increase the Average by 15.0 A-Ds. Keep repeating
steps 2 and 3 until the loadcell is stable or you’ve tried the entire range
of Average (300 A-Ds). If the loadcell is still not stable go to step 4.
4. Setting the Constant to higher values increases the filtering effect.
What to Do: Set Threshld to 0.0, Constant to 1.0 and Average to 300
A-Ds. Check the stability of the loadcell.
How to Do It: Save changes and exit to Display mode. Observe the
Center of Zero light. If it is on all the time your loadcell is stable within
¼ division. If the Center of Zero light blinks more filtering is required.
Go to step 5.
5. Repeat step 4 but increase the Constant by 1.0. Keep repeating steps 4
and 5 until the loadcell is stable or you’ve tried the entire range of
Constant (10). If the loadcell is still not stable, decrease your display
update rate and start over at step 1 using the new, slower display rate.
6. After the Constant value is established you may wish to lower the
Average value to improve display response time.
7. After a final value for Constant and Average has been set, enter the
Threshld value established in step 1. If this value is too small your
loadcell will act as if the filtering is off or not working. Increase the
Threshld value until your loadcell stabilizes.
If the Threshld value is too high your loadcell will react slowly to weight
changes.
When Harmonizer is properly adjusted the loadcell will be stable at zero
and will rapidly display a stable test force value.
