Abstract: In a method for optimizing an order in which certain points on a circuit board can be tested and evaluated, a coordinate system is established in a circuit diagram of a circuit board, and at least one locating point is preset. When an operator selects a signal path routing within the circuit diagram, the method can display the testing points in the selected signal path routing on a display device. After calculating the distance between each of the testing points and each of the at least one locating point, a group of distances is obtained. By comparing the distances, the minimum distance can be determined from the group of distances. The method further optimizes the order of the testing points according to the distance between each of the testing points and the locating point that consists of the minimum distance.

Abstract: A method for modulating multiple-instruments and multiple-sensors using an electronic device. The electronic device controls an instrument to measure the working parameters of an object, and controls a sensor to detect the working temperature of the object.
