1. A mobile independent electronic tester assembly usable for portable dual-range testing to determine the operability and status of a cruise control mechanism, said tester assembly comprising:

  • frequency determining means comprising means providing a controlled, selectively variable frequency test signal;

    means for simulating vehicular speed by sending the variable frequency signal from the frequency determining means to speed measurement input leads of a vehicle comprising the cruise control mechanism under test;

    means for adjusting simulated vehicular speed during a test to dynamically exercise the cruise control mechanism during testing;

    variable memory means comprising means by which calibrations for said controlled variable frequency are entered and which communicate with said frequency determining means to preset frequencies for simulating vehicular speeds; and

    means for indicating to a testing operator said determined vehicle speed.
