ABSTRACT:
User selection of meter ballistics is accomplished by separating the meter display from the meter drive circuitry. An input signal is input in parallel into appropriate level determining circuits, with the outputs being selected for processing by a microprocessor. The microprocessor processes the selected outputs according to a ballistic standard selected by an operator to generate a display signal. For LED displays the display signal has a bar component that illuminates all the LEDs up to the maximum level of the displayed output and a dot signal that illuminates only one or a very few LEDs around the maximum level of the displayed output.
