Interval of time
The duration of the sieving intervals can be selected in one-second
steps with the + / - keys. The pause is always one second long.
Continuous operation is set if the “-“ key is held down until “P” or “00”
appears in the display.
Due to the pauses in sieving, the sieving process is accelerated greatly
when sieving a substance that is particularly light (e.g. grain or plastic)
because, during the sieving pause, light material can fall through the
stationary sieve mesh and drop onto the next finer sieve fraction.
