1. Do not use any attachment that appears to be damaged.
2. Attachment must be properly installed. Hand tighten it.
Do not use wrenches or any other tools.
3. Do not exceed attachment capacity.
4. When installing gauge on a stand make sure to use all
necessary screws to secure unit.
5. Use eye protection devices when testing materials that
may shatter.

1. Do not use or store unit in extreme temperatures.
Note: Operating temperature is 0-45°C.
2. Do not use or store unit in oily, dusty or water splashing
areas.
3. If display shows stop test immediately and
release load. Over-load condition may damage the load
cell.
4. Do not apply force at an angle and avoid twisting the
shaft.
5. If gauge is not going to be used for a while, remove
batteries to avoid corrosion of battery terminals.
6. Use AC adapter that comes with the unit only. Any
other adapter will damage circuity.
7. Do not use any chemicals to clean outside case (including gasoline, alcohol e.t.c). Just use ordinary soapy
damp cloth.
8. Do not attempt to disassemble gauge. The warranty will
be voided.

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.
Note: When the AC adapter is used, the batteries act as a
memory back up system only.

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
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.

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.

The memory of the DFS series operates in three distinct modes:
1. On-demand memory mode (single)
2. Continuous memory mode
3. Standard memory mode
ON-DEMAND MEMORY MODE (SINGLE)ON-DEMAND MEMORY MODE (SINGLE)
ON-DEMAND MEMORY MODE (SINGLE)
ON-DEMAND MEMORY MODE (SINGLE)ON-DEMAND MEMORY MODE (SINGLE)
The unit comes from the factory set on the on-demand mode.
One hundred data can be stored in memory by pressing the
MEMO SET switch. If more than one hundred data are
forced into memory, the word FULL will appear on the
display. To recall the data in the memory press the RECALL
switch. The last data and memory position show up on the
display first. Any subsequent switch pressing will decrement
the data and memory position
By pressing the key, the last data in memory will be
erased. If unit is allowed to go OFF and then ON again, the
last data cannot be erased by pressing the key. To clear
the memory press RESET and ON switch at the same time.
The display will show momentarily and then go to
all zeros. If RECALL is pressed, the display will show
momentarily.

After the desired data has been stored in memory, set the
gauge in the RECALL mode and press the PEAK mode
switch. The last memory position will be displayed and also
the data in that position.
Subsequent manipulations of the peak switch will bring up
maximum, minimum, average data, and standard deviation.
See diagram below:

T o clear memory from all data, press RECALL switch first
and then press simultaneously the ON and RESET switches.
The display will show momentarily and everything
will default to MEASURE (ready) state.
After standard deviation, by pressing peak again the unit goes
to maximum. T o escape from statistics press the RECALL
switch. T o escape from RECALL press the RESET(ESC)
switch.
Note: If the “UNIT” switch is pressed after a set of data has
entered the memory and new data is attempted to enter the
memory in different “units”, the display will show
which means that this action should be avoided. You cannot
change units during the process of entering data into memory.

You can enter 100 measurements at once in this mode.
While force is applied on the shaft, press MEMO SET.
The display will be changing according to force applied and
the letter M will be blinking on top of the numbers. When
100 measurements have entered the memory , the M letter
will disappear momentarily and the word FULL will appear
on the display momentarily and the letter M will reappear
solid. You can recall each measurement by pressing the
RECALL switch. T o clear the memory press RECALL, then
RESET and ON at the same time and the cycle can be
repeated.
Statistics can be performed in this mode as previously
described. If the is OFF, statistics can be performed

into memory. Unit is now ready to accept the lower point
(limit). Use the same procedure to accomplish LO point
setting. If it is attempted to set LO point higher than the HI
point the unit defaults to the beginning of the procedure.

respectively if the corresponding set points are reached, HI,
GO and LO. These outputs can be used as alarms or indicators for the limits set. T o erase any or both of the set points,
just set them to zero. Erase HI point first.
Set the HI point to zero and press MEMO SET. Then set LO
point to zero and press MEMO SET . This is the only way
they can be erased from the memory. To check set points at
any time press the switch. The gauge comes from the
