Sieve Weighing Method

Open

There are two methods commonly used to measure the mass retained on each sieve as a result of a sieving operation. This option allows the person carrying out the test to choose the method appropriate to their requirements.

Selection	Action/Description

Selection	Action/Description
Open	Material retained on each sieve is to be weighed by adding it to the previous masses retained, one sieve at a time. The new combined (cumulative) mass is recorded for each sieve. The individual mass retained is calculated.
Open	Material retained on each sieve is to be weighed and recorded separately (that is, individually). The cumulative mass retained is calculated.

Weighing Pan Masses

Open

Although it is common that the method used to measure the mass retained in the Pan is the same as the method used to measure the mass retained on the sieves, it doesn’t have to be. This option allows the person carrying out the test to make the choice at the time of the test.

Selection	Action/Description

Selection	Action/Description
Open (Default)	Material retained in the Pan is to be weighed and recorded separately.
Open	Material retained in the Pan is to be weighed and recorded by adding it to the total mass retained,

Calculation Method

Open

While it is common for sieve analysis results to be reported as cumulative percent passing values plotted against the sieve aperture size, it is also possible for alternative reporting formats to be required. The other common formats are:

• Cumulative percent retained against the sieve aperture size

• Individual percent retained against the sieve aperture size.

This option supports this functionality, where it is required.

Selection	Action/Description

Selection	Action/Description
Open	Default Results are displayed, and reported, as cumulative percent (by dry mass) passing individual sieves.
Open	Results are displayed, and reported, as cumulative percent (by dry mass) retained on individual sieves.
Open	Results are displayed, and reported, as individual percent (by dry mass) retained on individual sieves.
