Abstract
A test system for performing a test of strain gauge resistors used on a pointing stick. The test system has a mechanical load applicator that holds the resistor and applies a mechanical force to the resistor. An electrical contactor makes and breaks an electrical connection with the resistor. An electrical tester is connected to the electrical contactor to measure electrical parameters of the resistor with and without the mechanical force. A calculator is connected to the tester and calculates several resistor parameters. The resistor parameters are indicative of the operation of the pointing stick.
