Application Examples – Continued
Page 11
Here is another example of a MULTI-LAMINATE application. As the number of laminate layers increases,
the likelihood of achieving a complete measurement, with all of the laminate layers defined and
measured, decreases. Also, as the overall thickness of the glass increases, the likelihood of a complete
measurement will also decline. The example to the right is a 6 glass layer, and 5 laminate inner-layer
assembly. The display screen of the GC3200 can only hold a limited number of values simultaneously on
one display. In this example there are too many values for one screen. On Screen 1 you see the first
sets of data. At the end of the data you will notice the word “MORE”. This lets the user know that
additional measurement data is available on the next screen. Screen 2 shows that additional data. You
will notice that the drawing at the bottom of the display is able to include all of the glass and laminate
layers on the screen. Only the data is separated onto two separate screens.
As explained previously, as the multi-laminate glass gets more complex, it becomes more difficult for the
GC3200 to provide a complete set of data. The example to the right shows an example such as this.
Even if the meter is NOT able to identify all of the laminate layers, it typically is able to still provide
supporting data that might be helpful to the user. Rather than place an ERROR message on the display,
the GC3200 will attempt to communicate as much data as possible to help you with your application. In
this example, the meter is not able to fully confirm the presence of a laminate inner-layer, so it will NOT
default to the G1 + L1 + G2 algorithm that was explained in previous examples. When the meter is not
able to confirm a laminate inner-layer, the meter will default to showing a “D” dimension that groups at
least one component into the dimension. The “D” dimension could include a variety of component
thickness values in its result. For instance, the “D” dimension could include a single piece of glass (G), or
it could be 1 piece of glass G + a laminate L (G + L). At other times it could include a G + L + G + L
combination. Every application is unique, so the value and meaning of the “D” dimension will also be
unique from application to application. When the meter knows for sure there is a glass or laminate
thickness, it will still show those values as before in the Results. However when the meter encounters an
unknown situation, it will default to the “D” value. Again, the GC3200 will provide as much valid data as it
can with each measurement.
For the example to the right, the following measurement result could occur (Screen 3). The GC3200
measured the G1 and L1 values accurately. However when it tested G2 it ran into an error condition, so it
defaulted to the D1 value of 9.5mm. If the user has some knowledge of the construction of the multi-
laminate assembly, they may know that the 9.5 mm represents a 10mm piece of glass. The D2 value
likely includes a 10mm piece of glass + L2 or L3 thickness. D3 appears to be representing a piece of
glass around 5mm, as well as the D4 value. So while the user may not know the exact values, it may be
possible to piece together the data that the GC3200 provides.
