GC3000 Warranty
The manufacturer warrants all models of the GC3000 to be free from defects in material and workmanship under normal use and service as specified within the
operator's manual. The manufacturer shall repair or replace the unit within twelve (12) months from the original date of shipment after the unit is returned to the
manufacturers factory, prepaid by the user, and the unit is disclosed to the manufacturers satisfaction, to be thus defective. This warranty shall not apply to any
unit that has been repaired or altered other than by the manufacturer. The aforementioned provisions do not extend the original warranty period of the unit which
has been repaired or replaced by the manufacturer. Batteries are not covered by warranty.
EDTM, Inc. assumes no liability for the consequential damages of any kind through the use or misuse of the GC3000 product by the purchaser or others. No
other obligations or liabilities are expressed or implied. All damage or liability claims will be limited to an amount equal to the sale price of the GC3000, as
established by EDTM, Inc.

When working with laminated glass that has a low e coating placed against the PVB inner-layer, the Glass-
Chek PRO is capable of helping you identify which surface has the low-E coating. To perform this function, the
meter must be switched into “PVB WITH LOW-E” mode (see page 2).
When testing laminated glass with Low-E, the meter will test laminated pieces of glass alone, and it will also
test laminated low-E glass that has been built into a double pane window assembly. For double pane window
assemblies, the GC3000 meter must be placed against the side of the window that contains the laminated low-
E piece of glass. The first screen that appears will show the thickness of the overall laminated piece of glass,
the air space, the second pane of glass thickness, and also the overall thickness of the double pane window
assembly. The second screen will show the make-up of the laminated low-e piece of glass. The meter has
been designed to add the thickness of the PVB layer to the thickness of the glass that contains no low-E
coating. For the piece of glass coated with low-E, the meter will display the actual thickness of the glass itself.
This means that the piece of glass that has an abnormal (larger) glass thickness (caused by adding
the PVB layer thickness to the glass thickness) will be the pane that is clear of any low-E coating.
The piece of glass that is displayed as a “normal” thickness (0.124” for example) is the pane that has
the low-E coating on it.
The display examples below correspond with how the meter would read the example at right. Screen 1
displays the thickness of the entire window. The “PANE 1” result on the first screen refers to the thickness of
the laminated low-E glass assembly. Screen 2 displays the details of the laminated low-E glass assembly only.
Screen 3 confirms the presence of a low-E coating and displays the type of Low-E.
The “normal” thickness of .124” (Screen 2 / Line 3) indicates the low-E coating is on the 2nd pane (surface 3) of
the laminated portion of the window.
