6.4 Switching On / Off
Turn on the AS 400 control with the mains switch (
I
) on the front side of the device.
When the device is switched off, it is completely disconnected from the mains.
Setting mode:
After switching on, the device is in the setting mode. The displays "time" (
H3
) and "speed" (
H6
)
show the last used values. The display "memory" (
H7
) indicates "on".
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 and the display "memory" (
H7
) indicates
"on". All other displays are off. 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 prevent dust emission
during the sieving.
Weigh the sample and put it on the uppermost test sieve (biggest mesh size). Make sure not
Place the complete sieve stack centrally on the device and clamp the sieve stack
(

Chapter "
Sieve Clamping Unit "standard"
").
Set the optimum speed and sieving time (
→
Chapter "
").
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 "
" automatically records the weights and allows for a
quick and simple evaluation of the sieve analysis. When the device is controlled via
EasySieve
®
, "ES" is indicated in the display "memory" (
H7
). A detailed description can be
found in the separate manual of the software.
