Caution!
Note the tester’s capacity of 200 lbF [1,000 N]. Producing a force greater than 150% of capacity
can damage the internal load cell. An overload can occur whether the tester is powered on or off.
Typical materials able to be tested include many manufactured items, such as wires, tubing, and other
samples. Items that should not be used with the tester include potentially flammable substances or
products, items that can shatter in an unsafe manner, and any other components that can present an
exceedingly hazardous situation when acted upon by a force.
The following safety checks and procedures should be performed before and during operation:
1. Never operate the tester if there is any visible damage to the AC adapter or the tester itself.
2. Ensure that the tester is kept away from water or any other electrically conductive liquids at all
times.
3. The tester should be serviced by a trained technician only. AC power must be disconnected and
the tester must be powered off before the housing is opened.
4. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.
5. Wear eye and face protection when testing, especially when testing brittle samples that have the
potential to shatter under force. Be aware of the dangers posed by potential energy that can
accumulate in the sample during testing. Extra bodily protection should be worn if a destructive
failure of a test sample is possible.
6. In certain applications, such as the testing of brittle samples that can shatter, or other applications
that could lead to a hazardous situation, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.
7. When the tester is not in use, ensure that the power is turned off.

2 POWER
The tester is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these
batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period
of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the
receptacle on the tester (refer to the illustration below). The battery will fully charge in approximately 8
hours.
Caution!
Do not use chargers or batteries other than supplied or instrument damage may occur.
If the AC adapter is plugged in, an icon appears in the lower left corner of the display, as follows:
If the AC adapter is not plugged in, battery power drainage is denoted in a five-step process:
The tester can be configured to automatically power off following a period of inactivity. Refer to the Other
Settings section for details.
If battery replacement is necessary, the battery may be accessed by removing the sheet metal cover on
the underside of the base.
1. When battery life is greater than 75%, the following indicator is present:
2. When battery life is between 50% and 75%, the following indicator is present:
3. When battery life is between 25% and 50%, the following indicator is present:
4. When battery life is less than 25%, the following indicator is present:
5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing.
Several minutes after (timing depends on usage and whether the backlight is turned on or
off), a message will appear, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone
audio indicator will sound and the tester will power off.

3 SETUP
3.1 Assembly
The lever is shipped disassembled from the unit to prevent damage in transit. To install, match the pin on
the cam mechanism with the corresponding blind hole in the lever hub. Then, tighten the plastic knob into
the threaded hole in the lever hub.
3.2 Mounting
Place the tester on a clean, flat and level work area free from vibration. If desired, the tester can be
secured to the work area with four 1/4-20 screws fastened into the underside of the base.
3.3 Sample setup
1. Secure the terminal into the standard terminal fixture or optional ring terminal fixture, as shown in
the figures below. Index the fixtures until the desired slot or ring size is aligned with the cam
mechanism adjacent to the lever. The fixtures will click when indexing to each size selection.
Fig. 3.1
Wire terminal fixture
Fig. 3.2
Ring terminal fixture (optional)
2. Rotate the lever clockwise until its end of travel.
3. Insert the loose end of the wire between the cams in the mechanism adjacent to the lever, as
shown in the figure below. Keep the wire taut as it is inserted.
Fig. 3.3
Cam mechanism
4. Rotate the lever counter-clockwise to engage the loose end of the wire, as shown in the figure
below. Continue rotating to produce force on the sample. The lever will reach its end of travel
before contacting the keypad / display housing.

5. When the test is complete, rotate the lever clockwise until the end of travel. The cams will open
and the wire will be released.
3.4 Installing the ring terminal fixture
To install or uninstall the standard terminal fixture or optional ring terminal fixture, loosen the screw in the
center of the fixture, remove, place the other fixture in the receptacle, and re-tighten the screw.

4.3 Menu navigation basics
Most of the tester’s various functions and parameters are configured through the main menu. To access
the menu press MENU. Use the UP and DOWN keys to scroll through the items. The current selection is
denoted with clear text over a dark background. Press ENTER to select a menu item, then use UP and
DOWN again to scroll through the sub-menus. Press ENTER again to select the sub-menu item.
For parameters that may be either selected or deselected, press ENTER to toggle between selecting and
deselecting. An asterisk (*) to the left of the parameter label is used to indicate when the parameter has
been selected.
For parameters requiring the input of a numerical value, use the UP and DOWN keys to increment or
decrement the value. Press and hold either key to auto-increment at a gradually increasing rate. When
the desired value has been reached, press ENTER to save the change and revert back to the sub-menu
item, or press ESCAPE to revert back to the sub-menu item without saving. Press ESCAPE to revert one
step back in the menu hierarchy until back into normal operating mode.
Refer to the following sections for details about setting up particular functions and parameters.

5 OPERATING MODES
Caution!
In any operating mode, if the capacity of the tester has been exceeded by more than 110%, the
display will show “OVER” to indicate an overload. A continuous audible tone will be sounded until
the MENU key has been pressed or the load has been reduced to a safe level.
Three operating modes are possible with the WT3-200. To cycle between the modes, press MODE while
in the home screen.
5.1 Real time (RT)
The primary reading corresponds to the live measured reading.
5.2 Peak (PK)
The primary reading corresponds to the peak tension reading observed. If the actual force decreases
from the peak value, the peak will still be retained in the primary reading area of the display. Pressing
ZERO will reset the value.
5.3 Break Detection (BRK)
Arms the tester for automatic data output, automatic zero, and/or automatic data storage upon sample
break, as configured in the Break Detection menu. This mode will only appear if enabled in the Break
Detection menu.
6 CHANGING THE UNITS
The WT3-200 can display five different measurement units. To change the unit, select Units from the
menu. The display will list the available units, as follows:
UNITS
* lbF
ozF
kgF
N
kN
The tester will always power on with the unit selected in this sub-menu.
7 DIGITAL FILTERS
Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection
of 1 will disable the filter since the average of a single value is the value itself.
To access digital filter settings, select Filters from the menu. The display will appear as follows:
