Fig. 16: amplitude mm/”g” display
In the display marked amplitude mm/”g” the double amplitude is shown as the
measured value. Hereinafter this measurement will be referred to as amplitude.
When the AS450 is switched on, the amplitude is pre-set to the last amplitude
used.
5.14.1.1 Setting the amplitude
reducing
• Press the
-
key (B3) to reduce the amplitude down to 0.2 mm.
Keep the keys pressed down for 5 seconds for fast adjustment.
If the level drops below 0.2 mm, 2.2 mm will appear again.
increasing
•
Press the +key (B4) to increase the amplitude to 2.2 mm.
Keep the keys pressed for 5 seconds for fast adjustment.
If 2.2 mm is exceeded, 0.2 mm will appear again.

When switching the AS450 on, the amplitude is pre-set to the last amplitude used
and can be switched to the sieve bottom acceleration mode.
• Keep the + and - keys (B3 and B4) pressed simultaneously for 2 seconds.
The display does not show any measurements straightaway after the switch-over;
the START key must be pressed first before the measurements are displayed.
In the display (Aa) marked amplitude mm/ ”g” a multiple of the “g” gravitational
acceleration is displayed as a measurement.
(1g = 9.81m/s ²)

5.15.1 Setting sieve bottom acceleration in “g”
from 0.7 – approx. 7 g
Your AS450 can of course only reach the sieve bottom acceleration at which an
amplitude of 2.2 mm is not exceeded in relation to the natural frequency.
reduce:
– button (B3) reduces the sieve bottom acceleration down to 0.7g.
– keep button (B3) pressed – after 5 seconds fast adjustment is possible
increase:
– button (B4) increases the sieve bottom acceleration up to approx. 7g.
– keep button (B4) pressed – after 5 seconds fast adjustment is possible
