POWERING GAUGE ON/OFF
The DF II Series gauge has a dedicated power
key. Depress the key to turn the gauge On or
Off.
When the gauge is turned on, the Chatillon®
Splash Screen is displayed for approximately 5
seconds. This display shows the gauge model
andcapacity,rmwarerevisionlevel,revision
date and website address for downloads.
Shown: The power On/Off button is located on the front
of all DF II Series force gauges.
CHARGING YOUR GAUGE
The DF II Series contains a Nickle Metal Hydride (NiMh) Battery Pack that can provide up to 20 hours of
continuous use on a single charge.
A Battery icon appears on the main operating display and
operates like a bar graph. When the gauge has a full
charge, the Battery icon appears full and is green. As bat-
tery power diminishes, the Battery icon will “open” and as
power drains, it will turn yellow to indicate a lower level of
charge.
You may view battery life remaining, by depressing the “i” key. The gauge will display the estimated
battery life based on current usage in hours.
The DF II Series gauge will alert you when the battery requires charging. The gauge will display “Re-
charge Required” and the battery icon will show as “opened” and red.
It is best to completely drain your battery before reharging. To recharge, plug the stereo jack connector
into the top housing. Plug the charger/adapter into your source power. Charge for 15-20 hrs to achieve
maximum performance. A thermistor is used to prevent excessive heat from damaging the battery pack.
The DF II Series has a universal 120/230V power supply.
NOTE: New NiMh batteries need to be
charged 3-5 times before they will hold a
full charge. This doesn’t mean charged
3-5 times in a row, but rather, charged 3-5
cycles under normal use.

LOAD BAR GRAPH
The DF II Series gauge features a dynamic bar graph
that shows the force or torque being applied to the
gauge.
The purpose of the bar graph is to provide a visual
indicator to the user when they are approaching the
sensor’s capacity.
The bar graph has a “T” for tension and a “C” for
compression to indicate direction of force. The bar
graphllsfromthecenterlineandchangesfrom
green to yellow to red indicating proximity to the
sensor’s capacity. If the DFS II-R-ND uses the STS
torque sensor, the bar graph will change to show
“CW” for clockwise and “CCW” for counter-clockwise.
SENSOR OVERLOAD PROTECTION
The DF II Series gauge features mechanical overload
protection up to 150% of the sensor’s capacity.
Mechanical overload protection is provided in the
tension and compression direction for sensors with a
capacity of 110 lbf (500N) and below.
SENSOR OVERLOAD DISPLAY
When the DF II Series gauge senses that the force
applied is approximately 116% of the sensor
capacity,thebargraphwillllandthelower
message line will display “OVERLOAD”.
PASSWORD PROTECTION
The DF II Series offers Password Protection for the unit
set-up. The Password feature may be accessed by:
-Pressing F3 (More) four times, scrolling down to

The DF II Series gauge may be used as a hand-
held instrument or mounted to a Chatillon® tester
for compression and tensile testing.
HANDHELD OPERATION
When using the DF II Series gauge for handheld
testing, make sure to apply the load axially to the
load shaft.
Keep the gauge perpendicular to the item being
measured to ensure axial loading. Use the op-
tional handle assembly (SPK-DF-HANDLE) for high
capacity loads.
TEST STAND OPERATION
When using the DF II Series gauge with a Chatil-
lon® tester, make sure that the gauge is secured
to the tester with the proper adapter if required.
Adapters may be required to ensure that the gauge
shaft is located axially to the sample under test. If
the gauge is not secured properly, you may get
faulty reading or cause damage to the loadcell.

SAVING RESULTS
The DF II Series can save 20 or 100 results
(depnding on model) in the gauge memory.
You may use our TCD WEDGE software (p/n
NC003164-D)tosaveinniteresultsandperform
automation, data acquistion and detailed measure-
ment analysis.
To save a result, apply load to the loadcell shaft.
Your gauge will display the load reading.
To save, select the F3 (More) key. This will take
you to the View display. Select F2 (Save).
If you do not want to save a result, select the Zero
key. This will zero the gauge and clear the result.
CLEAR SAVED DATA
To change MODE, you must clear all Saved Data
from the gauge’s memory. This is to ensure that
the gauge will correctly calculate statistics, since
results from different modes will cause erroneous
statistics.
In DF II Series gauges the following message
prompts the user to clear saved data:
“MODE [locked] CLR SAVED DATA”
NOTE: The DF II Series force gauge allows you to save results to memory for the purposes
of calculating statistics. Therefore, you cannot change mode if you have results saved in
memory. You must clear results from the instrument’s memory before you are allowed to
change the mode.
To change MODE, you must clear all Saved Data from the gauge’s memory. This is to ensure
that the gauge will correctly calculate statistics, since results from different modes will cause
erroneous statistics.

VIEWING RESULTS
The DF II Series displays results in the following
formats:
nActive Measured Result
nSaved Measured Result(s)
nPass - Fail Result
nLoad Limt Result
nLoad Average Result
nBreak Detect Result (DFS II Series only)
VIEWING ACTIVE RESULT
The DF II Series gauge will display the result in
Normal, Tension Peak (T-PK) or Compression
Peak (C-PK) modes.
The DF II Series gauge will display the measured
result, mode, units of measure, active options and
battery life.
Displaying Normal Mode Result
When the DF II Series gauge is in Normal mode,
the gauge will indicate the measured result, units,
active options, Tpk, Cpk and battery life. Select
the F1 (Mode) key to set the gauge in Normal
mode.
When in Normal mode, the gauge will display the
load that is currently being applied to the load sen-
sor. A compressive load is indicated as a “positive”
result. A tensile load is indicated as a “negative”
(-) result. The load bar graph will also indicate the
load and direction of load that is applied to the sen-
sor relative to the sensor’s capacity. The loadcell
bar graph is intended to assist you in preventing
overloads.Ifthebargraphisnearlylledandis
red, you should stop applying a load to the sensor.
See Load Bar Graph.
Displaying Peak Mode Result
If you want your DF II Series gauge to display the
peak result, you should change the gauge to either
Tension Peak (T-PK) or Compression Peak (C-PK)
depending on the direction you are testing. Peak
results will also show in the standard mode screen.
NOTE: If you perform a test in NORMAL mode and you want to view what the peak measure-
ment was they are displayed above and below the current active reading. You may also select
the Mode key and the gauge will display the peak result even if the test was performed in
NORMAL mode.
