CONSOLIDATION CYCLES
To measure the volume of the chamber contents, it is necessary to consolidate the Dry Flo during an
analysis. To do this, the analyzer performs a consolidation cycle. During a consolidation cycle, the
analyzer agitates the chamber (by rotational oscillation) while a plunger moves forward into it. When
the user-specified consolidation force is reached, the analyzer records the volume, then retracts the
plunger slightly.
To gather statistically useful data, the analyzer automatically performs a series of such consolidation
cycles during each analysis run. The number of consolidation cycles performed during an analysis
run is specified by the operator.
Because of initial settling of the Dry Flo, consolidation is less consistent in the first few cycles than in
subsequent cycles. These first cycles are called Preparation Cycles. The number of preparation
cycles is setup in the SOP. The software automatically discards data from these cycles before
making calculations.
Subsequent cycles produce quite consistent results. In order to derive meaningful statistical
information, it is recommended that at least two preparation cycles (the default number) and five
subsequent cycles be performed on each sample, for a total of seven cycles.
