Structures Testing Instrument User Guide 59921 V0217
The Structures Testing Instrument offers fine-tuned testing and several unit options.
Using a turn force wheel, you can apply up to 800 pounds of force to structures such as balsa wood or
basswood towers and bridges. You don’t have to destroy the structure to test it to the limit – just apply
pressure in small increments and stop applying pressure at the first sign of structural damage. And because
the system captures both the peak load (force) and the current load (force) on the display, the load that
breaks the structure is displayed. The tester can display the force in pounds, kilograms, and newtons.
With the tester’s software, you can graph the force as a line chart per structure and print it to analyze it
later. This software also enables you to connect the computer to a projector to display testing data in the
classroom.
Note:
Bridges tested should be no longer than the span column support and no wider than the structure
supports. Towers must be no taller than the 11-1/2" threaded rod and no wider than the acrylic tower shield.
