2 SAFETY
The following safety checks and procedures should be performed before and during operation:
1. 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.
2. 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.
3. Keep away from moving parts of the tester. Loose articles of clothing should not be worn. Long hair
should be covered to avoid a hazardous situation.
4. In those applications where samples can shatter, or other applications that could lead to a
hazardous situation, use of a machine guard is strongly recommended.
5. When the tester is not in use, ensure that the power is turned off to prevent accidental engagement
of any of the controls.

3 SETUP
3.1 Mechanical Setup
3.1.1 Assembly
The tester is shipped completely assembled.
3.1.2 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 (depth of 0.5 in.
[12 mm]).
3.1.3 Installing the ring terminal fixture or blank terminal fixture
To install or uninstall the standard terminal fixture or optional fixture, loosen the screw in the center of the
fixture, remove, place the other fixture in the receptacle, and re-tighten the screw.
3.1.4 Sample setup
1. Secure the terminal into the standard terminal fixture or optional ring terminal fixture, as shown in
the images 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.
2. Insert the loose end of the wire between the cams in the mechanism. Keep the wire taut as it is
inserted. If auto-start is enabled, the test will begin when the switch is activated (refer to later
sections for operational details). Refer to the image below:

3. Note the protective red safety guard (circled, below), which automatically rotates into position as
the cam mechanism closes.

Further instructions for configuring and using the gauge’s outputs are provided in the Communications
and Outputs section.
3.4 Connecting power
Plug one end of the power cord into its receptacle at the rear of the stand and the other end into a wall
outlet with local earth ground (3-prong connector).
Before turning on power, the following safety checks and procedures should be performed:
1. Never operate the tester if there is any visible damage to the power cord or the tester itself.
The WT3-201M is powered by 110V/220V. Any contact with this high voltage can cause
serious injury or even death.
2. Ensure that the tester is kept away from water or any electrically conductive liquids at all
times.
3. Make sure the electrical outlet powering the tester has local earth ground (3-prong connector).
4. The tester should be serviced by a trained technician only. Power must be disconnected
before disassembly.
After the above safety checks and procedures have been performed, the tester may be powered on and
is ready for operation.

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 WT3-201M. 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.
6 UNITS OF MEASUREMENT
The WT3-201M can display five different force 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
Note: Changing the unit within this menu will not set the default unit. To always power on automatically
with the desired unit, configure the unit in the Initial Settings 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 appears as follows:
DIGITAL FILTERS

9
Model WT3-201M Motorized Wire Crimp Pull Tester User’s Guide
Two filters are available:
Current Reading – Applies to the peak capture rate of the instrument.
Displayed Reading – Applies to the primary reading on the display.
Available settings: 1,2,4,8,16,32,64,128,256,512,1024. It is recommended to keep the current
reading filter at its lowest value for best performance, and the displayed reading filter at its
highest value for best stability.
8 PASS / FAIL LIMITS
8.1 General Information
Pass / fail limits are useful for tolerance checking with red and green indicators and audible tones. Set
point outputs are also provided, for triggering an external device such as an indicator or alarm in process
control applications. Two limits, high and low, are specified and stored in the non-volatile memory of the
tester and the primary reading is compared to these limits. The results of the comparisons are indicated
through the three outputs provided on the 15-pin connector, thus providing “under”, “in range”, and “over”
signaling.
8.2 Configuration
To configure pass/fail limits, select Pass / Fail Limits from the menu. The display appears as follows:
PASS / FAIL LIMITS
Upper Disabled
* Upper Enabled
125.0
Lower Disabled
* Lower Enabled
122.5
Either one, two, or none of the limits may be enabled.
The upper limit is displayed in the upper right corner of the display, and the lower limit is displayed in the
lower right corner, as shown in the Home Screen and Controls section. If only one limit has been
enabled, the word “OFF” appears in place of the other limit value. If neither limit has been enabled, the
upper and lower right corners of the display will be blank.
If the application only requires that a sample withstand a minimum specified force, set only the lower
pass/fail limit. If the value is below this limit, the lower red “X” illuminates. If the value is above this limit,
the green “checkmark” illuminates.
Note: Pass / fail limits and set point outputs reference the displayed reading, not necessarily the current
live load.
