APPLICATION ExAMPLEs (CONT.)
- Measurement Example four - Double Pane Ig with Suspended film
- Measurement Example five - LAMI + LOW E (Low E Coating against LAMI inner layer)
When working with laminated glass that has a low e coating placed against the laminate lnner-
layer, the Glass-Chek PRO helps identify which surface has the low-E coaling (2 vs 3). To perform
this function, the meter must be switched into LAMI + LOW E mode (see page 4 & 6). Please note
for the example below, that sTANdARd Mode has been set to fRACTIONs of an Inch, and the
ACTuAL Mode has been set to dECIMAL Inches.
The LAMI + LOWE Mode of the GC3001 meter will allow you to test laminated Low E places of
glass monolithically, and also with the laminated Low E glass assembled into a double pane (IG)
window. for IG’s, the GC3001 meter must be placed on the side of the window that contains the
laminated low-E glass. The first screen that appears will show the thickness of the overall lami-
nated piece of glass, the air space, the second pane of glass thickness, and also the overall thick-
ness of the IG. The laminated piece of glass will be denoted as G1/L1/G2 on the display screens.
screen 1 and 3 below show this example. screen 1 is displaying the information infractions of an
inch (sTANdARd), while screen 3 shows the data in decimal inches (ACTuAL).

the application being tested and how the display format was configured.

Resulting Measurement Displays:
Due to the application and display format, the
measurement will alternate the following two messages:
Display 1 shows fractional inches rounded to the nearest standard. Display 2 shows the actual
measurements in decimal inches. Notice how the actual measurements in 2 are slightly different than
the measurements in 1 because Display 1 shows the readings rounded to the nearest standard.
Display 3 shows that the low-E coating is on surface 2, and it indicates that the coating properties are
soft coat and have the performance of double-silver Low-E.
Display 1 shows fractional inches rounded to the nearest standard. Display 2 shows the actual
measurements in decimal inches. Display 3 shows that the meter did not detect a low-E coating on G1
or G2. Since the GC3200 only detects coatings on the first 2 panes, you may be required to test both
sides of a triple pane window to verify the presence of a low-E coating on the glass on the opposite
side of the window.
Display 1 shows the actual thickness of the window in MM. Since the “Standard” setting is set to
OFF, STANDARD dimensions are not displayed. The word “FILM” indicates suspended film between
the two panes of glass. Display 2 indicates that G1 does not have any low e coatings (“CLEAR” of
any low-E coating). In Suspended Film Mode, the GC3200 will NOT test G2 for Low E Coatings.
Display 1 shows millimeters rounded to the nearest standard. Since the “Actual” setting is set to OFF,
there is no display showing the actual dimensions of the glass - only the dimensions rounded to the
nearest standard. Display 2 shows that the low-E coating is on surface 3. Please note there are
times where the meter will not specifically designate surface 3, and may show the result as Surface 3
or 4. This means that the meter is only indicating the coating is on the second pane of glass. In that
instance, the user must test the window from the opposite side to confirm the exact low e surface.
