Automatic Compaction
Check that the black mark on the mold handle is at 6 o'clock. With a
loaded mold properly in the chamber and the chamber door closed,
press 〈START〉.
After beeping twice, the unit lowers the loading head. If the mold
notch is not aligned with the pin after the unit begins lowering the
loading head, then press 〈STOP〉, open the chamber door, align the
mold with the pin, close the door, and press 〈START〉. If the
loading head hits the top of the mold, the control unit displays the
error and the loading head will retract. Open the chamber door,
center the loading head, close the chamber door, and press
〈START〉 to resume compaction.
Step away from the unit as the Model 4140 compacts the specimen.
The unit will beep twice before starting any movement. The two
LED displays show the specimen height (updated each revolution)
and number of gyrations remaining. The lights beside the manual
compaction keys and the control unit screen show the compaction
progress.
With the Auto Output feature, the compactor automatically outputs
the gyration-versus-height data during compaction. To manually
output data, see page 2-18. With the Pressure Printout feature on,
the compactor prints the pressure-versus-number of gyrations data
at the end of the compaction cycle.
After the unit raises the ram, open the chamber door. Wearing heat-
resistant gloves, remove the mold from the compactor.
If desired, allow the specimen to cool before extruding it from the
mold. For more information on extruding the specimen see page
4-9. After extruding it from the mold, remove the specimen papers
from the top and bottom of the specimen.
Clean the turntable and the loading head with a degreasing cleaner.
