ISR TESTING

        To test the overhead resulting from the ADC ISR, when the first
        display window appears, press a key twice, very quickly. When the
        main window appears, it will say "TESTING ISR - PLEASE WAIT". This
        may take anywhere from a few seconds to several minutes. When it has
        completed this test, the display will read "ARMED -- BEGIN TEST". 
        
        If there is excessive overhead, an error message will appear, and
        the program will terminate. This test is performed whether or not
        the specific test is selected as described above.


CALIBRATION

        To access, press <ALT>-C

        When password is requested, enter it, and press <RET>

        Calibration factors and other variables are accessed by entering
        the corresponding number and pressing <RET>

        A "hidden" selection is 99, which gives the number of bytes of memory
        remaining, and the approximate A/D ISR overhead.


DROPOFF

        The amount of dropoff in the test waveform is determined by reading
        the RMS value of the first and last full cycles of the waveform, and
        storing this value as a ratio. A value of 1.00 indicates no dropoff;
        0.5 means that the last cycle is 1/2 the RMS value of the first cycle.
