ABSTRACT:
A speedometer/tachometer assembly for an automotive vehicle, such as a heavy truck, has a ten section DIP switch for calibrating the speedometer and a like switch for calibrating the tachometer. When set to all "0's", each switch causes the corresponding meter to be driven by a variable frequency signal from a corresponding sensor, as calibrated by a corresponding calibration factor that has been preloaded in the non-volatile memory of a microprocessor that operates the meters. When set to all "1's", each switch causes the corresponding meter to be operated from pre-calibrated data appearing on a data link. When set to any other setting, the setting determines the calibration factor that is applied to the uncalibrated signal, and this is used to drive the corresponding meter.
