During a calibration run, an operator can trade processing speed for calibration accuracy, depending on time constraints. The system displays the time taken to process an image and obtain a calibration reading. Then, the operator can adjust the scan resolution to increase or decrease the time needed to process an image. The processing time depends on the speed of the PC used in the test system. One of the calibration setup displays lets an operator tailor calibrations to specific speedometers.
Operators can choose equation coefficients and other parameters for use during a calibration.
The display seen by a production operator shows basic information about calibration status and results. No operator intervention is required during testing. A graphical user interface simplifies the configuration process. Figure 2 shows one of the screens used to calibrate the test system, and Figure 3 shows the screen an operator sees while calibrating speedometers. The figures show two different types of speedometers, which the software accommodates easily.
