MeltLab upgrades for XP/Win7 
Extra records filing, curver disappearing from screen
Summary: Some installations suffer from a problem of over- sensitivity to changes in the signal from the cup stand.
The MeltLab AI (Artificial Intelligence) detects a cup on the stand and a sample being poured by the voltages coming
from the cup stand. A few customers have reported “ghost” analyses where non-poured samples filed with empty curves, and
where removing a cup from the stand caused the curve to disappear from the screen. (Currently the screen is supposed
to clear when a new cup is placed on the stand.)

Extra records filing, curver disappearing from screen
Summary: This feature measures the grain boundary stress as a measure of shrinkage. The shrinkage potential is rated
from 1 to 10 with 10 being the highest shrink potential. This value is then presented in the standard data formats for
screen, and for reports. But the value can also be reported in a Pass/Fail mode similar to Ductile Nodularity. The
underlying stress measurement is also presented graphically on screen when the presentation of the Zero curve is
activated in the derivatives window.
