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.

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 WT3-201. 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 CHANGING THE UNITS

The WT3-201 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 appears as follows:

Model WT3-201 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 SET POINTS

8.1 General Information

Set points are useful for tolerance checking (pass/fail), 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 non­volatile memory of the instrument 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. These outputs can be connected to indicators, buzzers, or relays
as required for the application.

8.2 Configuration

To configure set points, select Set Points from the menu. The screen appears as follows:

SET POINTS
Upper Disabled
* Upper Enabled

25.0
Lower Disabled
* Lower Enabled

22.5

Either one, two, or none of the set points may be enabled.

If two set points have been enabled, they are displayed in the upper left corner of the display. If only one
set point has been enabled, the word “OFF” appears in place of the value. If no set points have been
enabled, the upper left corner of the display will be blank.

When set points are enabled, the following indicators are shown to the left of the primary reading:

Note: Set point indicators and outputs reference the displayed reading, not necessarily the current live
load.

– the displayed value is greater than the upper

force limit (NO GO HIGH)

– the displayed value is between the limits (GO)

– the displayed value is less than the lower force

limit (NO GO LOW)
