• Select the isotherm method as either Dynamic Dewpoint
Isotherm (DDI) or Dynamic Vapor Sorption (DVS). DDI
will create a dynamic isotherm and DVS will create a
static or equilibrium isotherm. The other choices will
adjust based on which method is selected.

Figure 4: Sample cup and lower block assembly
• Figure 4: Sample cup and lower block assembly illustrates
the proper positioning of the parts in the lower block. The
air cylinder is placed into the bore of the base block. It
should slide into the block easily and settle at the bottom
of the bore. The weigh pan connects to the scale and
holds the sample cup. For best results, verify cleanliness of
all parts.
