This video outlines a custom designed automatic system used to test the actuation force of touch screens for quality control.  A Mecmesin computer-controlled MultiTest-i force measurement system combined with an x-y table is used to create a "point map" of actuation force at set positions.  The x-y table moves the touch screen in a pre-programmed path at sub-millimetre accuracy.  At each pre-programmed location the test proble is lowered to "touch-on" the screen and the actuation force is captured as electrical contact is made.

The Mecmesin CrimpTest-1 is a horizontal, motorised wire terminal tester, designed for ease of use, rapid throughput and high duty cycle operation. Rugged construction, simple controls and a clear display make this compact, benchtop unit an ideal quality checking instrument for wire terminal manufacturing equipment, right at the point of production.

This video shows a MultiTest 2.5-xt measuring the insertion and withdrawal force of electrical connectors.  A custom made fixture holds the male and female connectors while Emperor software controls the movement of the test stand, and records the forces at the requisite points in accordance with test standard BS 5057.

This video shows a quality control test on a solenoid. The resistance force when a solenoid is energised is a critical quality parameter. The computer-controlled MultiTest-i range is ideal for programming the test sequence and displaying the load versus displacement characteristics of the solenoid.
