All DFS models come from the factory with the batteries not
installed. Before attempting to use the gauge install the four
AA batteries (provided) observing Figs. 1, 2 and 3 below.
Remove battery plate with a coin or appropriate screw driver.
Install 4-AA batteries as shown in Fig. 2 observing proper
polarity. Make sure lip engages properly before tighting the
battery plate screw.

First press the ON switch to turn power ON. The display will
show momentarily all the indicators shown in Fig.1 and then
settle at lb (oz) and some arbitrary number with (usually but
not necessarily all zeros).
Assuming that the proper attachment is installed and the unit
is positioned as desired, press the ZERO and ON switches
simultaneously. The display should show all zeros, which
means that the gauge is “T ARED”.
How to Change UnitsHow to Change Units
How to Change Units
How to Change UnitsHow to Change Units
After the power is turned ON and gauge is “TARED”, by
pressing the UNIT switch the instrument will change from
lb(oz) to kg(g) to N and the cycle is repeated.
Caution: The gauge will default to lb (oz) (initial setting)
after power OFF regardless of what unit was previously
selected. To avoid above situation, see page 7.
The gauge is now ready to measure force according to the
factory settings shown in Table 1.
After measurements are finished, press the OFF switch to
turn unit off.
Note: The gauge will power off automatically in 3 minutes if
the OFF switch is not pressed. If the AC adapter is in use,
the AUTO-POWER-OFF function is inoperative.
Change of Measuring ModeChange of Measuring Mode

As was mentioned in previous pages the gauge is set from the
factory in the average mode. The sampling rates for the
average mode are 0.125, 0.25, 1 and 2 seconds (selectable).
In the PEAK mode if the sampling rate is set for 1/1000 sec.,
the actual peak force is captured. If another sampling rate is
chosen the maximum average force is captured. T o change
from average to peak mode press the PEAK switch once.
The display will show a negative sign in front of the digits.
This means that the gauge is ready to measure tension. If the
PEAK switch is pressed one more time the negative sign will
disappear and the gauge is ready to measure compression.
One more press of the PEAK switch will bring the unit back
to average mode.
The gauge is able to measure average, peak tension, and peak
compression in one operation. When in the average mode,
push on the shaft for a period of time and then pull the shaft
and release. When you press the PEAK switch the peak
tension appears on the display. One more push of the peak
switch and the display will show the peak compression. T o
cancel the peak value from the memory press the RESET
switch.
The gauge is set to go to the average mode when the power is
turned on. T o change this condition (go to peak on POWER
ON) see page 7.

! Flow Control
Flow control can be accomplished by CTS input and software.
1. Control by CTS
When CTS is a “space” (5 ~ 10VDC), communica
tions are enabled. When CTS is a “mark”
(-5 ~ -10VDC), communications are disabled.
2. Software flow control
If software flow control is selected, communications
flow control can be accomplished thru RS232C by
sending XON or XOFF. XON (enable: ASCII
position D1#H11). XOFF (disable: ASCII
position D3#H13). If “disabled” is over 5 seconds,
Er06 is displayed momentarily , unit defaults to
measure mode and communications stop.
! Over-load output
When load exceeds approximately 120% of gauge's capacity
an open collector transistor turns ON (there are two OC NPN
transistors, one for tension and one for compression). The
output of these transistors can be used as an alarm or to stop
a process, thus protecting the gauge or the sample (material)
under test.

CalibrationCalibration
Calibration
CalibrationCalibration
The DFS series is an easy series to calibrate. At the same
time certain caution should be excersised not to lose the
calibration data in the process.
! Before proceeding with calibration
a) Secure a stand or some kind of fixture.
b) Secure calibration weight
c) Calibration weight has to be precise,
full scale and in Kg/g only.
d) Avoid vibration totally.
Note: If the analog output is used, steps 1 thru 15 must be
used. If the analog output is not used, steps 1 thru 11 must be
used. When steps 1 thru 11 are used, the analog zero maybe
slightly off.
Calibration ProcedureCalibration Procedure
Calibration Procedure
Calibration ProcedureCalibration Procedure
1. Turn power off. Use hook attachment and mount unit on
a stand or fixture up-side-down.
2. Press MEMO SET first and hold, then press ON and hold
for approximately 4 seconds till display shows CAL.
3. Press MEMO SET . Display will go to hex data. W ait
approximately 10 minutes for the unit to warm up.
4 . Zero position calibration
Press MEMO SET with no load. Down arrow will blink
and after 6 seconds it will go on solid and display will
show a hexadecimal number between 7E0 and 8C0 which
has no particular meaning to the operator.
→
5. Hang calibration weight. Press MEMO SET . Upper arrow
will blink and after 6 seconds it will go on solid. The
display will show a hexadecimal number depending on
the particular model under calibration. This number has
no meaning to the operator.
6. Now SP AN calibration is complete. Turn power of f.
7. Take unit out from stand or fixture and place it in a
horizontal position.
8. Press MEMO SET first and hold, then press ON and hold
for approximately 4 seconds. The display will
show CAL.
9. Press MEMO SET and wait approximately 30 seconds.
10.Press MEMO SET again. Arrow will blink and then go
solid.
11.Calibration is now complete. Turn power off. DO NOT
press MEMO SET before turning power off, otherwise
you will have to start with step 2 again.
12.Keep unit in horizontal position and press RECALL and
ON simultaneously and hold for approximately 4 seconds
till display shows .
13.Press MEMO SET . The unit will display along
with a hexadecimal number depending on the output
residual analog voltage.
14.Measure analog output voltage and adjust to zero using
the and switches. If switch is pressed, the
output voltage increases. If the switch is pressed, the
output voltage decreases.
15.Press MEMO SET and then turn power off.
Note: After step 12, be careful not to touch the ON key .
If the ON key is touched accidentally , the display will go
to some hexadecimal number. To default press ON key
twice.
The display will show the number as in step 13 above.
