section. Standard dies have a flat entrance and exit. When the die is out of the
barrel it cools down quickly. The longer it is out the longer the wait for the
temperature to stabilize. Minimizing the time the die stays out of the machine
will increase the number of tests you can run. When the temperature on the
front display is within 0.2 C of the set point you can begin the next test.
Loading material will cause a small temperature change even if temperature set
point was locked in. The melt time (360 seconds) will allow ample time to get
the temperature to set point before the first data point is collected. Always
leave the machine clean. If it is going to sit at room temperature for an
extended period of time you may wish to coat the barrel with a light machine oil
to prevent rusting. The oil will need to be purged from the machine before
accurate data can be obtained.
