Abstract: A method for testing an electronic component. The method includes connecting the electronic component to a test machine; specifying search range limits, low-to-high transition edge and high-to-low transition edge found criterion, and number of outcomes in a trial including multiple tests specified as proof of low-to-high transition or as high-to-low transition; computing values for initial trial parameters; if low-to-high transition edge not found: executing a low-to-high trial and adjusting trial parameter values based on results of step executing low-to-high trial; if high-to-low transition edge not found: executing high-to-low trial; and if either low-to-high or high-to-low transition edge not found: adjusting trial parameter values based on results of step executing high-to-low trial and repeating above steps beginning with the step having the condition if low-to-high transition edge has not been found.

Abstract: Apparatus and method are disclosed for measuring the quantity of a liquid, such as crude oil, transferred to or from a storage tank with all measurements being taken through an opening near the bottom of the tank. A water detecting probe is extendable through the opening a selected distance below the opening in order to detect the presence of water at a selected level below the opening and generate a detection signal. A sampling device is connectable to the opening for taking samples of the liquid transferred to or from the tank. A pressure sensor is connected to the opening for generating a pressure signal indicative of the pressure of the liquid in the tank. A computer is provided for using the pressure signal to generate a level signal indicative of the level of the liquid in the tank.
