Double Pane Windows
The GC3200 will specify if the coating is located on Surface 1, Surface 2,
Surface 3, OR Surface 3 or 4. If the meter does not specifically identify
Surface 3, you can move to the other side of the window to confirm the low
e surface.
Single Pane Windows
The GC3200 will specify if the coating is located on Surface 1 or Surface 2
of a single piece of glass.
Triple Pane Windows
The GC3200 will specify if the coating is located on Surface 1, Surface 2,
Surface 3, or Surface 3or4. By moving to the other side of the window, the
meter can specify Surface 5 and Surface 6. The GC3200 detects the
presence of low-E coatings on the middle pane of a triple pane unit. It will
either show results of Surface 3, or Surface 3or4. If there are multiple low-
E coatings, the GC3200 will only identify the nearest coating.
Low-E Detection Capabilities
The electronics that detect the presence of the Low-E coatings are impacted by the surroundings of the meter. This has been explained
elsewhere in the manual by showing proper hand placement on the meter and positioning of the glass when testing. The Low-E detection
circuitry is affected by conductive materials that are detected by the meter. Conductive materials could include the metal spacer in the window
or muntin bars (grid) inside the window itself, just to name a few. Keeping the meter at least 2 inches away from any metal/conductive material
when taking measurements will result in the most accurate Low-E measurements.
One additional note regarding Low E detection. If your application contains more than one low e coating in the window, the Glass-Chek ELITE
will only identify the first (nearest) Low E coating that it encounters. Testing from the opposite side of the window would allow you to identify
the other Low E coating in the window. The GC3200 detects the presence and location of low-E coatings on the following applications:

Identifying the Type of Low-E:
In addition to identifying the location of low-E coatings, the GC3200 determines the type of low-E on your window. The meter will specify it as
“hard coat”(aka pyrolytic or on-line coating) or “soft coat” (aka sputtered or off-line coating). If the Low E is soft coat, the meter will also specify
the number of silver-layers as single, double, or triple, based on the coating’s energy performance. If you happen to know the manufacturer of
the glass, in many cases you can identify the exact type of low-E coating used to make the window. A convenient reference chart is included
with the GC3200 meter, that lists many of the common Low E coatings used in the USA. Here are some examples:
