Both jaws of the specimen clamp are adjustable, so the test specimen can be positioned precisely in the center regardless of material thickness. Force is applied to the lower end of the specimen by a pair of rollers. The rollers, which are attached to a driving disc located directly behind the pendulum, push against the test specimen and deflect it from its vertical position. The pendulum applies increasing torque to the specimen as it deflects further from its original position.  The test point reading occurs when the pendulum mark aligns with the appropriate driving disc mark (7 1/2° or *5°), which points to the stiffness reading on the dial point.  

The final reading will depend on the range in which the test is being conducted and what scaling factor to use.  The instrument outputs the moment load applied to the test specimen in TABER Stiffness Units (g · cm).

Note: The right hand roller includes a ratchet stop mechanism that greatly reduces the potential for inter-operator error caused by over or under-tightening.  The travel on the right hand assembly automatically stops when the roller contacts the specimen.

To allow the testing of materials with different stiffness properties, range weights can be applied to the pendulum.  For extremely light weight materials, a compensator range weight is mounted to the top of the pendulum.  Range weights of **0, ***0 and ***0 &ampampampampquotTaber Units" are mounted to the bottom of the pendulum and required for stiffer materials.  An optional range weight set of ***0 and ***0 Taber units is required for test ranges 7, 8 and 9.
