III.8 Removal of Trough and Lid from Instrument
When the test is complete, the Lid will automatically raise up a small distance off of the trough.
This is a visual indication that the test has ended. Push and hold the UP arrow on the instrument
control panel until the Lid has raised to its upmost position. Then disengage the Lid from the
Compression Plate by pressing the release buttons (See Figure III-3b). Clean the excess powder
that clings to the Lid.
Remove the Outer Catch Tray from the trough and dispose of the excess powder in the Tray.
Remove the trough from the instrument and dispose of the powder sample in accordance with
lab procedure. Clean the Trough with the Cleaning Brush (Part No. PFT-612) which came with
the instrument.
Note that the perforated screen may require special attention with powder particles that have
been trapped in the openings. To remove the perforated screen, unscrew the three screws located
underneath the trough.
III.9 Clean-up
The Cleaning Brush serves to remove excess powder from the Trough and Lid. This may be
adequate for repeated testing of the same powder types where the potential for cross-contamination
between samples is not really an issue. Be sure to clean pins of the lids and compression plate
to ensure proper alignment.
For more thorough cleaning, the use of an air hose, water, or a cleaning solvent may be desired.
When using a liquid for cleaning, make sure to dry the Trough and Lid thoroughly so that moisture
contamination does not become an issue with the next sample.
Do not use compressed air to clean the PFT.
