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.
