5. I am using a multiple rate test, but the first rate never started.
It is possible that you never reached your starting position. Try increasing your Packing
Force or changing the starting position to one you will reach prior to the melt time
expiring.
6. The ram just purges the barrel after the Melt time expires.
Verify the settings specified in section 1.2 Windows OS settings.
Verify that the Trend is not set to “0” zero in
Run.
Verify that the setup you are using has the correct machine specified.

I used the over pack function in RUN and now the ram returns to the uppermost park
position not what I previously set it for?
Once the OVERPACK function is used the machine automatically adopts a park position of
5.0mm. To return to the previous park position, just press the EDIT key at the machine,
press the left/right arrow until PARK POS. is displayed and then press EDIT, type in the
desired park position, press ENTER to accept and then press ESC. Now press the “up”
key or HOME in the RUN screen and the ram should return to the desired park position.

9. “I've over forced the rheometer and now it's taking forever to purge or just won't purge.”
Press UP, so the plunger is not putting pressure on the material in the barrel. Remove
the die by unscrewing the die nut holder. Take the die and nut holder completely out
and purge the rheometer by pressing SHIFT then DN then YES, as usual, to purge.

"The X-Head of the rheometer will only move Up but not Down and / or the test will not
start when I press the RUN button."
