Method and apparatus for measuring response time
Abstract
A method of measuring the response time of an electrical instrument which generates an output signal in response to the application of a specified input, in which the output signal varies as a function of time and when subjected to a step input approaches a steady-state value, comprises: (1) applying a step input to predetermined value to the electrical instrument to generate an output signal; (2) simultaneously starting a timer; (3) comparing the output signal to a reference signal to generate a stop signal when the output signal is substantially equal to the reference signal, the reference signal being a specified percentage of the steady-state value of the output signal corresponding to the predetermined value of the step input; and (4) applying the stop signal when generated to stop the timer.
