*
*
*
*
*
*
*
*
Return value: none
*
Description: This routine converts the word format waveform data to
*
voltage values using values that describe the waveform.
*
These values are stored in global arrays for use by
*
other routines.

ConvertWordDataToVolts
short *wordData which is a pointer to the array
of read word values
double *wordVolts which is a pointer to the array of
calculated voltages
unsigned long AcquiredLength which is the number of data
bytes read
double yInc which is the voltage difference represented
by adjacent waveform data digital codes.
double yOrg which is the voltage value of digital code 0.
unsigned long AcquiredLength,
double yInc, double yOrg )
