7.0 OVERVIEW OF OPERATING MODES

The WTT-110 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 Advanced Setting, section 10, page 10, for additional information and
to change the update rate.

8.0 C

HANGING UNITS OF MEASUREMENT

12.0 CALIBRATION

The WTT-110 Pull Tester has been calibrated in accordance with factory proceedures
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 WTT-110 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

WTT-110 is well secured
in the vertical position.

Caution

■ Select a material that is strong

enough to support 50 Kg of weight.

9.0 GENERAL OPERATING PROCEDURES

1. Press On/Off key. During power-up, the WTT-110 performs a self-test routine.

During this procedure, the maximum capacity of the system will be temporarily
displayed in selected units of measurement. Then the unit should display zero.
Occasionally the last one or two digits might be something other then zero.
Additionally, the selected units will be shown.

2. Select the desired operation mode. To set for Peak Capture Mode, press the PEAK

key once. The peak indicator will be shown on the display when the system is set
for peak capture mode (highest value measured and stored until reset to zero). To
set for Average Mode, make sure the peak indicator is not shown. Press the PEAK
key until indicator is no longer illuminated. In this mode, the display is constantly
updated 3 times per second .

Note: The Display Update Rate can be set to update 1, 2, 3, 5, 10 or 20 times per
second (5 times per second = 0.2 seconds). Refer to Advanced Setting, section

10.4, page 11 for additional information and to change the update rate.

3. It is necessary to zero-set (“tare”) the WTT-110 before starting each force measure-

ment. Press the ZERO key for this purpose. The ZERO key is also used for clearing
the currently stored Peak value from display memory whenever desired.

4. Select the smallest suitable slot in the

Wire Terminal Fixture based on the
diameter of the wire and the physical
dimensions of the connector. Rotate
the fixture so the selected slot is in
the 3 o’clock position so it is closest
to the Wire Clamp Fixture.

5. Place the cable connection into the

fixture such that the main part of the
connector is retained on the inside of
the fixture and the sleeve and cable
will pass through the slot toward the
Wire Clamp Fixture. When pulling
on the cable, the terminal should be
well secured.

11.2 Analog Output

The analog output (-1...0...1 VDC) can be used for any data acquisition or data
recording device. Pull Force data will be expressed as a negative voltage. The
signal can be set to zero (reset) by performing a ZERO (tare) function. +1 VDC
and – 1VDC refers to the maximum and miniuml full scale (end of nominal
measuring range).

6. Insert the free end of the cable using
a small amount of tension into the
Wire Clamp Fixture and rotate the
handle clockwise until the cable is
clamped between the two metal
surfaces.

You are now ready to begin the
pull test.

7. Continue to rotate the lever
clockwise. The pull force on the

terminal connection will continue to
increase as the lever is rotated.

DO NOT EXCEED THE
MAXIMUM CAPACITY OF THIS
UNIT (110 lbs/50 Kg/500N) OR
DAMAGE COULD RESULT.

8. Eventually, the cable will pull out

from the terminal connection. The
test is now complete. If set for Peak
Capture Mode (refer to Overview of
Operating Modes, page 6), the peak
force value will be stored in the
display memory. If set for Average
Mode, the display would have been
updated throughout the test cycle.

9. To perform another test, repeat the steps detailed above. If operating in Peak

Capture Mode, be sure to press the ZERO key to delete the previously stored
peak value.

9.10 Additional Operating Information
Low Battery

When battery charge is low, the LO BAT indicator will blink on and off in the
LCD Display indicating that the batteries need to be charged. Charging time
of fully depleted batteries is approximately 18 hours when the unit is off. The
adapter/charger automatically shuts off when the battery is at full charge to
protect the battery. The adapter/charger can be used to power the unit during
battery charging, but this will lengthen the charging time. Refer to Charging
the Battery, section 4, page 4, for additional information.

Auto Power Off

If the gauge is on and there is no activity for 10 minutes, the unit will automati­cally power off to conserve battery charge. PWR appears above the display digits
to notify that there is 1 minute before power off. If the adapter/charger is power­ing the gauge, auto power off function becomes inactive.

Temperature Compensation

The WTT-110 utilizes a built-in temperature compensation system to provide
optimum accuracy and to prevent signal drift. If the user would like to disable
this feature, please refer to the Advanced Settings section on page 10.

DJUSTING ADVANCED SETTINGS

There are several adjustable settings that can be changed from the factory defaults to
customize the WTT-110 to meet the exact requirements of the user. These settings are
saved in the microprocessor and are recalled each time the system is powered up.

10.1 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.

■ Switch off the instrument.

■ Press and hold PEAK- and MODE-buttons.

■ Press ON/OFF-button.

■ Wait until TRK oFF is displayed.

■ Release PEAK- and MODE-buttons.

10.2 Selecting the baud rate of the RS232C interface (Default: 2400)

On the WT-110RS model ONLY, the speed of the data transfer for the RS232C
interface can be adjusted as follows:

■ Switch off the instrument.

■ Press and hold RESET-button.

■ Press ON/OFF-button.

■ Wait until f01 is displayed, then release RESET-button.

■ Select function f04 by repeating to press the PEAK-button until f04 is shown

on the display.

■ Select appropriate baud rate (2400/4800/9600/19200) by repeating to press

the MODE-button.

■ Press RESET-button to save your settings.

10.3 Switching off Auto Power-Off function (Default: 10 min)

While operating under battery power the instrument will be automatically
switched off after approx. 10 minutes on inactivity. This Auto Power-Off func­tion can be deactivated, which may become necessary when monitoring the
fluctuation of applied forces for a longer period of time. This function is
disabled when the instrument is powered by the AC-adaptor.

■ Switch off the instrument.

■ Press and hold RESET-button.

■ Press ON/OFF-button.

■ Wait until f01 is displayed, then release RESET-button.

■ Select function f03 by repeating to press the PEAK-button until f03 is shown

on the display.

■ Select setting (10/OFF) by repeating to press the MODE-button.

■ Press RESET-button to save your settings.

10.4 Change the 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 1000 Hz, which allows the precise capturing of the peak values. The read­ings on the display, however, are refreshed 3 times/sec only for the convenience
of the human eyes. You may increase or decrease the factory settings for them to
match your personal demands.

■ Switch off the instrument.

■ Press and hold RESET-button.

■ Press ON/OFF-button.

■ Wait until f01 is displayed, then release RESET-button.

■ Select function f02 by repeating to press the PEAK-button until f02 is shown

on the display.

■ Select refresh-time (1/2/3/5/10/20 times/sec) by repeating to press the

MODE-button.

■ Press RESET-button to save your settings.
