WTT-110
Wire Terminal Tester - Pull Tester |
Measuring Range
0-50 Kg / 0-110lbs / 0-500 N
(User Selected)
Accurately measure the pull or “pull-off” force on most soldered or solder-less wire terminals, crimped connectors and similar wire terminations.
The WTT-110 is an easy to use all-in-one, single-range solution suitable for a vast majority of terminal testing applications eliminating the need to purchase any additional grips, fixtures or accessories.
Suitable for wires AWG 30 to AWG 8 (diameters from 0.010" to 0.130"). |
 Precision strain gauge sensing provides a resolution of 1/5000 with an accuracy of 0.5%
| | Display force values in “peak-hold” or “continuous” measurement mode | | Operates from AC power or built-in rechargeable battery via supplied adapter/ charger | | Test for UL 486 & Mil Spec and other standards |
| | Fabricated from steel and stainless steel, machined to the highest tolerances | | Model WTT-110RS includes RS-232 and analog outputs for external data recording | | Includes Traceable Calibration Certificate |
|
To operate, simply follow these steps:
1. Select the appropriately sized slot in the Wire Terminal Fixture and rotate to the front position
2. Insert the terminal and wire so that it is secured on the back-side of the slot
3. Route the wire so that it passes between the lever and the lever clamp
4. Select Peak-Hold or Continuous Measure mode using the PEAK key
5. Press the ZERO key to perform tare function
6. Rotate the lever clockwise, which clamps the wire and begins creating a pull force on the terminal
7. Read current force and breaking force on the digital display
 Calibration for all WTT-110 models can easily be verified or re-certified with a single 50 Kg hook weight as described below:
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 at the edge of a strong bench or desk (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 known weight from one of the teeth on the wire terminal fixture by hooking a loop of the material over the selected tooth.
