Recalibration Procedure

For recalibration, you would need a solid and vibration-free rack and a test weight
(50kg or 100kg), preferably Class M1, which complies with the international
standard.

Before calibrating the load cells, the pull force fixture must be brought back to the
zero-position. In order to do this, adjust the selector switch for the pull speed to “0”
and switch on the instrument.

1. Switch off the instrument using ON/OFF button.

2. Press and hold MODE, PEAK and RESET buttons simultaneously.

3. While keeping the above buttons pressed, press the ON/OFF button until CAL is

indicated in the display and the calibration weight code (??) is shown. Then
release all buttons. The WTTM is now in calibration mode

4. Press the MODE button. The signs SNC and –00– flash for approx. 10 seconds

followed by the indication ZER 88888.

5. To confirm the calibration of the zero point press the RESET button. The

indication SCN 88888 flashes on the display for approx. 15 seconds, followed by
PEK 88888. The first step of the calibration is now complete.

6. Hang the calibration weight on the terminal adapter. When the weight hangs
perpendicular and still, you may save the full-scale value.

7. Press the PEAK button. The display flashes for approx. 15 sec. with the sign
SCN 88888 followed by the sign END 88888. After a further period of approx.
5 sec., the sign OK 88888 indicates that the calibration was successful. The
instrument switches off automatically.

8. Should the calibration fail, the display will show ERR 88888 instead. The original
calibration datas are still saved in the memory. You may remove the weight and
repeat the recalibration procedure

5.3 Operating modes

The WTTM can be set to operate in one of two distinct operating modes: Peak
Capture or Average. In Peak Capture Mode, the system measures the force at a
frequency of 1000 Hz (1000 times per second) and displays the highest force
measurement. The peak value remains on the display until a higher force value
is measured or until the user presses the ZERO key.

In Average Measurement Mode, the system measures the force at a frequency
of 1000 Hz (1000 times per second) and displays the average each time the dis­play is updated. The factory default display update rate is 3 times per second (1
time every
1/3 second).

Note: Refer to section 7.3, page 8, for additional information and to change the
update rate.

6.0 BASIC PROCEDURES

6.1 Changing the pull speed (default: 50mm/min)

The pull speed can be adjusted
according to the testing standards.
You need a small and a large screw
driver to do this. The selector switch
is protected by a screw thread cap,
in order to avoid an unintentional
manipulation of the pull speed.

To adjust the pull speed:

1. Switch off the instrument and
unplug the power supply.

2. Loosen the protection cap with
the large screw driver (flat or phillips head?).

3. Adjust the selector switch to the desired pull speed (How? Using the small

screw driver?)

4. Replace and tighten the protective cap.

10.0 CALIBRATION

The WTTM Pull Tester has been calibrated in accordance with factory procedures and
is certified to perform within the stated accuracy specifications shown in the
Specifications section found on page 18. Assuming the unit is handled with care
and operated as detailed in this manual it should remain accurate for an extended
time period. If however, it is subjected to forces that exceed its maximum range or
if it is not properly cared for, it might need to be recalibrated.

It is recommended that the calibration is verified at least on an annual basis and more
frequently if feasible. Normally, instruments of this type go out of tolerance from one
day to the next and rarely on a regular periodic basis.

A calibration procedure is provided in this manual, however it should only be per­formed by individuals properly trained for this type of service and with the appropriate
certified standards (known weights or secondary force measuring system such as a
load cell, etc.).

Re-Calibration Set-up

1. Remove the lever by unscrewing it in a
counter-clockwise direction and move
the Wire Clamp assembly out from the
path of the hanging sample.

2. Position the WTTM in a vertical
position so that the keypad & display
are at the top (refer to photo). Be sure
to secure it so it can not topple over
when the weight is attached.

3. Using a heavy-duty monofilament
(fishing line), wire or similar, suspend
a 50 Kg weight from one of the teeth
on the wire terminal fixture by hooking
a loop of the material over the selected
tooth.

4. Temporarily, remove the weight and
follow the Re-Calibration Procedures
shown on page 16.

■ Make sure that the

WTTM is well secured
in the vertical position.

Caution

■ Select a material that is strong

enough to support 50 Kg of weight.

6.2. Selecting the baud rate of the RS232C interface (Default: 19200)

The speed of the data transfer for the RS232C interface can be adjusted to match
your data acquisition rate by changing the baud rate as follows:. This is possible
by changing the baud rate:

1. Switch off the instrument.

2. Press and hold RESET button.

3. Press the ON/OFF button.

4. Wait until f01 is displayed, then release RESET button.

5. Select function f04 by repeating to press the PEAK button until f04 is shown

on the display.

6. Press the MODE button repeatedly until the appropriate baud rate

(2400 / 4800 / 9600 / 19200) shows on the display.

7. Press the RESET button to save your settings.

6.3. Changing the up-date (refresh) rate of the display (Default: 3/sec)

The force applied to the load cell of the instrument is internally processed at a
rate of 1000Hz, which allows the precise capturing of the peak values. The read­ings on the display, however, are refreshed at a default rate of 3 times/sec. You
may increase or decrease the factory settings to match your personal demands as
follows:

1. Switch off the instrument.

2. Press and hold the RESET button.

3. Press the ON/OFF button.

4. Wait until f01 is displayed, then release the RESET button.

shown on the display.

6. Press the MODE button repeatedly until the desired refresh rate

(1 / 2 / 3 / 5 / 10 / 20 times/sec) appears on the display

7. Press the RESET button to save your settings.

6.4 Temperature Compensation (default: SET = on)

In general, it is recommended to have the this function turned on as long as it
does not effect your measuring results. Only when measuring very minute
forces over a longer period of time at a slow rate and under stable environmental
conditions might it be useful to switch this off.

1. Switch off the instrument.

2. Press and hold PEAK and MODE buttons.

3. Press ON/OFF button.

7.0 OPERATING PROCEDURES

7.1. Switching on the instrument, selecting the measurement unit and

operational mode

1. Switch on the instrument by pressing the ON/OFF button.

After a power-up self test and calibration (approx. 20 sec.), the display will
indicate the last selected measuring unit, function and the value 0.00.

2. Select the desired operation mode (indication of the current measurement

value or the peak value) and the measuring unit by pressing the PEAK and
MODE buttons simultaneously. The current settings will be indicated on the
display. When you choose the PEAK mode, the peak value will be always
indicated on the display (drag indicator function).

7.2. Resetting to zero before each measurement

It is necessary to zero-set the instrument before starting
each pull force measurement. Press the RESET button
for this purpose. The RESET button can also be used
for deleting the peak value updated in the memory.

7.3 T aking Measurements

NOTE: Select the smallest suitable slot for the test

sample diameter.

1. Place the cable connection into the adapter, so
that the sleeve of the cable connector stays
securely inside the ring and cannot be pulled out
through the slot.

2. Insert the free cable end with slight tension into
the clamping fixture. The nut in the pull force

fixture will help you to find the right position

for the cable.

3. Holding the cable tight and securely, close the
protection cover.

N

0.0

– 11 –

4. The motor starts and closes the pull force
fixture. Hold the cable end securely until the
pull force develops.

5. The rotational motion of the pull force fixture
tears off the cable from the terminal joint. The
motor stops when the maximal pull length has
been reached.

6. When you open the protection cover, the pull
force fixture returns back to the original
position and releases the cable.

7. During the measurement, the force progression
can be read off the display.

The peak value, which mostly appears before the
connection breaks, is captured at 1000Hz and is
indicated when the PEAK button is pressed (so
long as the drag indicator function was not active).

Depending on the wire strength and the related standard, the following
tensile strength should at least be achieved.
