To create a new test setup, click on the "Add New Setup" icon on your Setup page. Be sure
to fill in all the blanks to complete your test setup. Be sure to include the Program Name,
Melt Temperature, Melt Time, Data Point Setup, Die or Dies used and Acquisition mode.
There are four important control variables, which govern the start of a test:
Melt Pause,
Start Position, Delay, Temperature, Melt Time and Die size.

Melt Time
: The
Melt Time
is the minimum amount of time the material will be exposed to
test temperature in the barrel before the first rate begins.
Park Position:
The
Park Position
is the position where the ram remains idle and the
position to which the ram returns after completing a run or sample purge.
Melt Pause Delay:
The
Melt Pause Delay
is the amount of time the plunger will stay idle at
the start position. For low viscosity polymers this is set to zero or kept it to a minimum due
to the fact that the polymer may run out of the barrel while the plunger is idle. For
polymers that are higher in viscosity this is set close to the melt time to allow the polymer
to “relax” prior to starting the test.
Start Position:
The
Start Position
is the position where the first programmed ram rate
begins.
