Place the Outer Catch Tray into position on the trough. Place the Inner Catch Tray into position
on the trough, this will lock into place when properly seated. Use the Powder Scoop (Part No.
PFT-611), which comes with the instrument, to place the powder sample in the Trough. Any
spillage is conveniently captured by the Inner and Outer Catch Trays. When sufficient sample
has been placed in the trough, rotate the Shaping Blade on the Inner Catch Tray to distribute the
sample evenly around the trough. Rotate in a clockwise direction until the sample is completely
distributed. Then rotate in a counter-clockwise direction to remove excess sample.
An alternate loading procedure was explained earlier in Section III.1 when the Sieve Kit is used.
Repeat the steps in the preceding paragraph once the Trough is full with powder.
Remove the Inner and Outer Catch Trays from the trough. Return excess sample material in
the Catch Trays to the container from which the powder came or throw it away in accordance
with your lab policy.
III.7 Placement of the Trough and Lid on the Instrument
Take the trough loaded with sample material and weigh it again. Subtract the weight of the
Trough to obtain the weight of the sample material. Enter this value into the Sample Information
section of the main screen on the Powder Flow Pro software.
Make sure that the Compression Plate on the instrument is in the upmost position. Use the Up
arrow on the instrument control panel to reposition the Compression Plate if necessary.
Place the trough on the Drive Disc of the instrument so that the center of the trough aligns with
the pin in the center of the Drive Disc. Rotate the trough by hand until the pin on the outer edge
of the Drive Disc engages one of the holes on the bottom of the Trough’s outer edge. When this
occurs, the trough will lie secured in a flat position, centered on the drive plate.
Take care not to disturb sample.
Place the Outer Catch Tray in position around the trough. This serves to catch any spillage of
the sample material when the test is running.
Attach the appropriate lid to the Compression Plate on the instrument. You may choose to do
this before placing the trough on the instrument. It is simply a matter of operator preference.
The Lids are sharp. Be careful when installing and removing.
The test is now ready to begin. Refer to the section on Powder Flow Pro Software for details
on running tests from your PC. When the Run Test button is pushed on the main screen, the
Lid will automatically descend onto the Trough, pausing for a brief period of time just prior to
making contact with the powder sample in order to perform an autozero.
Be sure to clean pins of the lids and compression plate to ensure proper
alignment.
