Thank you for choosing the DFC Force Controller.
This Quick Reference Guide is an overview of the basic
functions available with your instrument. For detailed
instructions on instrument setup and operation, please refer
to the electronic user manual. You may download a copy

INTRODUCTION
The DFC may be used as a classic digital force gage. It may
also be used as a digital controller when connected to the
FMM Digital Force Tester.
The DFC, as a controller, is the only gage available that
lets you setup an automated test, including the operating
parameters of the force tester. Configure speed and
distance limits through the DFC.

KEYPAD AND NAVIGATION
The DFC keypad is multi-functional. There are four keys.
ON/OFF/MENU KEY
This key is used to power the gage on/off. Press to
power the gage on. Press and hold for 3 seconds to
power the gage off.
This key is also used to access the Setup Menu. When
the gage is powered ON, press to access the Setup Menu.
This key is also used to navigate UP when in the
Setup Menu. p
ZERO KEY
This key is used to zero the displayed values. Press
to zero load and if connected to the FMM digital force
tester, zero distance.
This key is also used to navigate DOWN when in the
Setup Menu. q
SOFTKEY 1
This is the left arrow key. It is used to move out of a
setup when in the Setup Menu. t
This key may also be mapped to a specific function.
The Setup Menu has a Key setup function where you
may assign how Softkey 1 performs. For example, you
can assign a SAVE function to the key. When pressed,
the measured values are "saved" to memory.
SOFTKEY 2
This is the right arrow key. It is used to move in to a
setup when in the Setup Menu. u
Like the Softkey 1, it also may be mapped to a specific
function. For example, you can assign a MODE
function to the key. Pressing the key can change the
operating modes of the gage. You can switch from
Real Time to Peak Tension by pressing Softkey 2.
DISPLAY LAYOUT
The force gage features a high-resolution OLED color
display with adjustable backlight. The backlight may
be adjusted from a setting in the Main Menu.
The DFC features a primary and secondary
display window.

USING TOLERANCE LIMITS
Use tolerances to setup "pass" and "fail"
measurements. You may specify a Limit 1 and a
Limit 2 to create a tolerance band. Measured results
that equal or fall within the range created by the two
limits are considered "pass" results. If the measured
result falls outside the band created by the two
Limits, the result is considered a "fail" result. A "fail"
results displays in RED.

SAVING RESULTS
The DFC feature an internal memory for saving
results for the purpose of calculating and displaying
statistics. You may save up to 99 individual results
in memory.
To save results to memory, you must configure
a softkey with the SAVE function. Press the SAVE
softkey to save the displayed results to memory.
Results saved to memory MUST be of the same type.
You cannot have mixed type results. For example, you
cannot save tension results with COF results. Results
MUST be of the same type.
Results obtained using the TESTS feature are saved in
pairs. For each test, there is a Load and Distance result
(L-D). You cannot save results from different types of
tests. For example, you cannot save results from a
Load Limit test with results from a Break Limit test.
Each load-distance pair of results must have come
from the same test type: Load, Distance or Break.

Management of the DFC memory is important to
ensure correct statistical analysis. Always clear old
results that are from a different test method.
CLEAR RESULTS FROM MEMORY
Results in memory may be cleared individually
or collectively. To clear an individual result from
memory, go to the STATS view. Select the results you
want to clear. Select the "X" (delete) key.
To clear all results from memory, go to the Memory
setup and select CLEAR. This will erase all results for
the gage's memory.
VIEW STATISTICS
You must configure a softkey with STATS to view
statistics. When results are saved to memory, you
press the STATS softkey to view results in memory
and the statistics for those results.
EXPORT RESULTS
You must configure a softkey with SEND to export
to an external device via Bluetooth, RS232 or USB.

CHARGING BATTERY
Connect the USB cable supplied with your DFC to the
USB connector at the base of the gage. Connect the
opposite end of the cable to the USB connector on a
source device, i.e., personal computer, USB adapter.
If the DFC is connected to an FMM test frame
and power to the frame is ON, the DFC battery is
continuously charged.
