Operating the Device
31
Standby mode:
By pressing the button ( H1 ) after power on, the device can be put into standby mode. In this
mode, only the LED of the button ( H1 ) is lit. Except for the button ( H2 ), all buttons are
inoperable.
6.5 Selection of the Test Sieves
The selection of the test sieves depends on the sample quantity as well as the particle size
distribution. The gradation of mesh sizes and accordingly the measurement points should be
selected in such a way that the complete particle size range of the sample is covered at regular
intervals. The wider the particle size range, the more test sieves should be used.
6.6 Performing a Sieving

Determine the empty weights of the test sieves and the collecting pan.

Place the sieve stack with increasing mesh size on the collecting pan.

Each test sieve is provided with an O-ring, which serves as a seal to minimise dust emission
during the sieving.

Weigh the sample and put it on the uppermost test sieve (biggest mesh size). Make sure not
to exceed the maximum feed quantity .

Place the complete sieve stack centrally on the device and clamp the sieve stack
(

Chapter " Inserting the Test Sieves ").

Set the sieving time (

Chapter " Controlling the Device ").

Start the sieving process.

After the end of the sieving process, weigh the individual test sieves and the collecting pan
including the particle size fractions present therein.

Determine the mass of the particle size fractions (weight after the sieving less the respective
empty weight).

The evaluation software " EasySieve
®
" automatically records the weights and allows for a
quick and simple evaluation of the sieve analysis. A detailed description can be found in the
separate manual of the software.
