1.0 INTRODUCTION

Thank you for selecting the CHECK•LINE WTT-110 Wire Terminal Pull Tester for
your requirements. With correct use and proper care this product should provide
many years of precise and accurate testing. Please read the entire operation manual
thoroughly before using this instrument for the first time. The information contained
herein will help assist users to achieve accurate and repeatable results as well as
prevent damage with improper set-up or operation.

This instrument is designed for measuring tensile strength of soldered or solder-free
cable joints with end sleeves, pins, solder pins or similar wire terminal components
in the field of quality control or design validation.

Safety Precautions

Wear appropriate eye protection at all times.

The load cell can be damaged if the internal measuring system is overloaded.
Do not exceed the maximum measuring limit of 50 Kg (110 lbs. or 500N).

Transport and store the instrument with great care. This reduces the risk of
damage to the load cell or other minor mechanical problems which can result
in inaccurate measurement results.

Operate the instrument in appropriate environments only. The instrument
is equipped with a temperature compensation for a temperature range of
32 to 120 °F (0° to 40°C) and should be used in this temperature range only.
Do not expose this device to liquid or operate in high-humidity environments.

3.0 SETUP

Place the WTT-110 Wire Terminal Tester on a level and stable work area where the
user can perform the testing in a comfortable manner. The surface should be clean and
grease-free, so that the instrument does not slip.

Make sure that there is no residue from the pack­aging materials stuck under and around any of the
operating components especially in the recessed
area around the rotating terminal fixture (see photo)
and under the lever arm base plate, etc.Use of
compressed air to clear any debris from these
areas is recommended.

Please note that the instrument weighs approximately 30 pounds (14 kg), so please use
necessary precautions when lifting and moving. We suggest that the location is in close
proximity to an AC-Power outlet.

Locate the lever and screw it in to the
threaded hole in the rotating wire clamp
fixture, as shown in the photo. Turn the
lever in a clockwise direction to screw-in.
Continue until it is “hand-tight.” DO NOT
OVERTIGHTEN.

HARGING THE BATTERY (REQUIRED BEFORE FIRST USE)

For safety reasons, the WTT-110 is supplied with the batteries fully discharged.
To obtain maximum battery life we recommend that you charge the internal NiCd
battery for approximately 18 hours before first using this instrument the first time.

Select the appropriate plug adapter for the outlet type and country of use. Plug the
charger into an AC-outlet and plug the other end into the receptacle on the left side of
the WTT-110. Charge the batteries.

Note: The BAT indicator is shown on the display when the batteries are being charged
and turns off when the batteries are fully charged. When the batteries are nearly
discharged, the "LO BAT" indicatory will blink on and off.

5.0 AC-O

PERATION

The WTT-110 can be operated using the AC-Adapter/Charger. The batteries are being
recharged while plugged into the AC power source. Total battery recharge time will be
significantly longer then if recharged while turned off.
