PRECAUTIONS
qRead the instruction manual completely before attempting to use the DFIS or ACCUFORCE
2 (AF2) Series. By following the instructions contained in this manual, the optimum accuracy and
performance can be attained.
IMPORTANT NOTE: The DFIS and ACCUFORCE 2 (AF2) gauges are identical in function-
ality. The procedures, specifications and operations in this manual apply to both products
unless noted.
qTurn off the DFIS/AF2 Series before connecting or disconnecting any cables to the instrument.
qDo not overload the DFIS/AF2 Series! The instrument can handle an overload of up to 150% of the
rated full scale. The display will read “- - - -” when the gauge exceeds approximately 120% of full
scale. When the force applied is removed and “- - - -” is no longer displayed, the gauge may not read
above 121% of full scale in the Tension Peak or Compression Peak modes. Therefore, you must
contact your local distributor to ensure the load cell was not damaged, unless you are 100% sure the
force applied did not exceed 150% of full scale.
qThe DFIS/AF2 Series is designed for axial loading only! Applying load on an angle or eccentric
loading may cause an erroneous reading.
qDo not use tools to attach the shaft adapter and accessories to the gauge. Use “finger-tight”
pressure only to prevent damage to the load cell.
IMPORTANT NOTE: Before using your new DFIS/AF2 Series, fully charge the rechargeable
Nicad battery by plugging the supplied battery charger into the battery charger jack at the top
of the gauge and the proper AC outlet. Use only the battery charger supplied with the gauge.
Using other chargers can overcharge and damage the battery.

1.3 RECHARGINGBATTERIES
A rechargeable NiCad battery powers the DFIS/AF2Series. Since NiCad batteries continue to discharge
when not in use, it may be necessary to recharge the unit before use. When the battery power begins to lose
its charge, the Battery Indicator will appear on the display . To recharge the battery, plug the battery charger
included with the gauge into the correct voltage source and insert the charger jack into the receptacle on the
end of the gauge . Charge the battery for 10-12 hours to yield approximately 8-10 hours of continuous
operation. The gauge can be operated continuously with the charger connected.
_ WARNING -
Before using the gauge, please fully charge the Nicad battery. Use only the battery charger supplied with
the gauge. Using other chargers can overcharge and damage the battery.

1.4 PHYSICALDIMENSIONS
1.5 REVERSIBLEHOUSING
The DFIS/AF2 Series is shipped shaft-down for stand-mounted applications, and the display on the front of
the gauge is configured accordingly. For performing operations in which the gauge will be hand-held, it may
be desirable to rotate the front of the casing so that the display and logo will be shown right side up. To do
so, remove the two screws from the back of the casing, carefully rotate the front of the casing 180 degrees
being careful not to pull, pinch, or twist the wires inside, and then reinstall the screws.
NOTE: When removing the screws to the back casing for any reason, please take the proper ESD (Electro
Static Discharge) precautions. Touching the circuit board without taking the proper ESD precautions may
cause damage to the circuit board.

1.7 ABOUT THE DISPLAY
The display is an LCD seven segment display that is easily read even at a distance. The display illustrates
different symbols such as: battery symbol (BATT) indicating the battery is running low; a “C” for compres-
sion or a “T” for tension. The peak operational modes are also displayed (T PEAK, C PEAK). The right
portion of the display indicates the force measurement units (LB, KG, N). The display updates 4 times per
second.
1.6 ABOUT THE KEYPAD
The keypad consists of four dedicated keys (PEAK, UNITS, ZERO, XMIT). The keypad is operational when
the power switch, located on the side of the gauge, is in the ON position.
Figure 1.2

1.10 SETTING UP FOR SAFE USE
The DFIS/AF2 Series should be properly setup before accurate and most of all, safe measurements can be
made.
Only when you have verified that you will be conducting a safe test, proceed as follows:
1. Determine what and how it will be tested and verify that the DFIS/AF2 Series can handle the test.
2. If desired, mount the gauge in the test fixture.
3. If you will be powering the instrument from the AC line, plug the charger into its jack on the instrument.
Plug the charger into the correct AC voltage outlet (the required AC voltage and frequency are listed on
the charger).
4. Otherwise, if you will be powering the instrument from batteries, fully charge the batteries before using.
IMPORTANT NOTE: Before using your new DFIS/AF2 Series, fully charge the rechargeable
Nicad battery by plugging the supplied battery charger into the battery charger jack at the top
of the gauge and the proper AC outlet. Use only the battery charger supplied with the gauge.
Using other chargers can overcharge and damage the battery.
5. Attach all necessary attachments and plug in the cables. Route the cables so they do not interfere with
the test.
6. Zero the gauge by depressing the ZERO key.
7. Attach the specimen and begin to take measurements.

2.0 FRONTPANELOPERATION
The DFIS/AF2 Series can operate in one of the three modes: Normal, Data Collect and Configuration.
2.1 NORMALMODE
The principal function of the Normal mode is to provide indications of load applied to the load cell.
Instantaneous force, peak-tension and peak-compression readings can be displayed and scaled in a
variety of units of measure.
2.1.1 Selecting Units of Measure
Force indications can be displayed in LB, KG, or N. The gauge displays the active units of measure on the
LCD display. Pressing the UNITS key will cycle between the three available measuring units.
With gauge power ON, depress the UNITS key to cycle through available force measurement units (LB,
KG, N). Release the key when the desired unit is displayed.
2.1.2 Selecting Type of Measurement – Capturing Peaks
The gauge continuously measures instantaneous tension or compression forces (normal readings). It also
captures peak-tension and peak-compression forces. The gauge displays which measurement is being
indicated. Pressing the PEAK key will cycle between the available force measurement modes.
With gauge power ON, depress the PEAK key to cycle through available force modes (C, T, T PEAK, C
PEAK). Release the key when the desired unit is displayed. The display will indicate C until tension is
applied to the loadcell. This will cause the display to indicate tension (T).

2.1.3 Zeroing
Zeroing allows you to exclude the weight of accessories and attachments from the indicated force readings.
It also clears captured peak tension and compression readings. To zero the gauge, momentarily press the
ZERO key. Only the current measurement type (i.e., NORM, T-PK, C-PK) will be zeroed. To zero and clear
all measurement types press and hold the PEAK key and then press the ZERO key. Zeroing the gauge
takes approximately 0.5 seconds.
2.1.4 Transmitting Readings
Pressing the XMIT key will cause the gauge to transmit a single reading (current measurement type and
current units) through the output port (MITUTOYO or RS-232). If the gauge is in the NORM mode, the data
value (NORM, T-PK or C-PK) displayed on the screen will be transmitted. If the gauge is in the DATA
COLLECT mode, where a series of measurements are taken, the gauge will transmit an averaged value of
the outputs at the loadcell.
To TARE, affix the required adapter or fixture to the gauge. Orient the gauge so that it is positioned as it
will be during testing. Depress the ZERO key to tare the gauge.
To ZERO, after a test, depress the ZERO key to zero the force readings. Removing power to the gauge
will also zero the force readings.

2.3 DATA COLLECT MODE
The DFIS/AF2Series can accept and execute commands through the RS-232 serial port. The command set
is tailored to make it easy to configure and operate the instrument under computer control.
2.3.1 About Data Collect Mode
Data transmitted by the gauge in Data Collect mode is a filtered average of 45 instantaneous force readings.
Digital filtering is employed to eliminate false readings resulting from noise and vibration.
The external device, which the gauge is communicating to, e.g. personal computer, must be configured to
transmit and ASCII character “F” to the gauge. This signals the gauge to go into, or out of DATA COLLECT
mode.
When the external device sends an ASCII character “?” or “X” to the gauge, the gauge will always respond
even if the instantaneous reading is a zero value. This permits real time data collection to begin at a force
reading or zero value. The ASCII character “?” or “X” is a request to the gauge to transmit data.
The gauge will return to Normal mode when it receives and ASCII character “F”. The table on the next page
shows the available ASCII characters and their functions.
The diagram below will illustrate how the gauge operates based on these ASCII characters.

3.0 CALIBRATING THE DFIS/AF2 SERIES
The DFIS/AF2 Series may be field calibrated, however, for optimum performance, it is recommended that
your gauge be factory calibrated at least every other year or more frequently depending on your frequency
of use. Field calibration is recommended every 6 to 12 months. A 5-point calibration is required where five
different calibrated weights are applied to the load shaft at increments of 20%, 40%, 60%, 80% and 100% of
capacity.
qYou must have a way to mount the load cell vertically oriented before applying tension and compres-
sion force.
qThe DFIS/AF2 Series should be calibrated using deadweights representing 100% of the rated full scale
with 20% increments. For example, calibrating a 10 lb. gauge, the deadweights must be in 20%
increments for a total of 10 lbs. at correct gravity.
qYou must have a safe method of axially applying the deadweights to the load cell in both the tension
and compression directions.
LB
LB
50
- WARNING -
The DFIS/AF2 Series should always be calibrated to full capacity. A 500 lb capacity gauge should be
calibrated at a full scale reading of 500 lbs. If you have a 500 lb capacity gauge, yet you use the
gauge between 0 and 100 lbs, YOU CANNOT calibrate the gauge as thought the full load is 100 lbs.
3.1 CALIBRATION PROCEDURE
This section leads you step-by-step through the calibration process for a DFIS/AF2Series:
qSTEP 1 Gauge Pre-Set
With gauge power OFF, PRESS and HOLD the UNITS and PEAK key.
Switch gauge power to ON. Select the units to be used during the
calibration. Depress the UNITS key to scroll through the available
units (LB, KG, N). Press ZERO to select the desired unit.
qSTEP 2 Select the desired capacity that will be calibrated (2, 10, 50, 100, 200
or 500). Depress the UNITS key to scroll through the available
capacities. Press ZERO to select the desired capacity.
