int DMMSetReadInterval(int nDmm, double dReadInterval)
This function sets the reading interval (the time it takes to make a single reading). For
Apretures between 625us and 5.066s it may be set between 0 to 1s. For Aperture values
between 2.5us and 521us it can be set between 0 to 65ms. This value effects most
measurement functions including the various triggered modes. The default of this
parameter is set to 0, resulting in the fastest measurement rate at the selected Aperture.

int DMMSetReference(int nDmm, double dRef)
This function sets a measurement reference. Unlike DMMSetRelative, which uses the
current measurement as a reference, DMMSetReference provides the facility to set the
reference to dRef. Once set, it is subtracted or divided from subsequent measu
