Measurement Cycles dialogue
The Measurement Cycles dialogue allows the system to be set up to perform
multiple measurements of a sample. It also defines the cleaning sequence used after
a measurement has been completed.
Excess sample often remains on the tray and has to be removed manually. The
Cleaning section of the dialogue enables this excess sample to be fed through the
system into the vacuum cleaner. In a hopper-equipped Scirocco, the excess sample
can be withdrawn directly from the sample tray into a second vacuum unit attached
to the sample lid.
The cleaning cycle becomes active when the Cleaning required check box is ena-
bled. The user must then set:
The Clean Duration, the time beyond the measurement period during which
the vibrating tray, compressed air supply and vacuum cleaner are left running
in order to clear the sample from the tray.
The Vibration Feed Rate to use during the clean cycle.
The Dispersive Air Pressure required to convey the sample through the cell
during cleaning.
In addition, if a second vacuum cleaner has been installed on a hopper Scirocco,
selecting the Second vacuum fitted option triggers the second vacuum cleaner at
the end of the sample measurement and remove all excess sample directly from the
sample tray during the clean procedure.
