13.3.11At the end of the cut off time an alarm will sound indicating the test is nearly
over. Cut the material that was extruded during the cut off period and weigh it
on a scale (a resolution of 0.001 grams is preferred) and record the weight (in
grams) on the Extrudate Weight screen, then press Done. Press Continue.
13.3.12If the Post-Test Comments option was selected, the operator can enter any
appropriate comments on the screen that appears next. Press Done to move
on.
13.3.13The next screen allows the operator to view test results. Record the results or
print them to an optional printer if desired. Press Done when finished to
return to the main screen.
13.3.14Allow the remaining material to purge from the cylinder and then, if the
machine is equipped with the optional WLD, press the [7] (TOP) button to
raise the weight support platform.
13.3.15Thoroughly clean the piston, cylinder and orifice as described in Section 16.
IT IS IMPERATIVE THAT THE MACHINE IS CLEANED AFTER EACH
TEST. If no more tests are needed, remove the piston and orifice from the
furnace before turning the MP1200 off to prevent them from being welded in
place as any material left in the barrel hardens.
