or inches. Touch the back of the meter to find your desired setting. Push the button to select it.
Next, determine whether you want the meter to: 1.) round measurements to the nearest Standard, 2.) display the actual
dimensions or 3.) display both standard and actual. For more information about rounding to Standards, see the “GC3000
Standards Table” in this manual. To turn Standard rounding on or off, select the “STANDARD” option. If your dimensions are set
to inches, you will have the options: FRACTION, DECIMAL or OFF. If your dimensions are set to millimeters, you will have the
options: ON or OFF. Touch the back of the meter to find your desired setting and push the button to select it. PLEASE NOTE, if
the STANDARD option is selected in inches, the glass thickness designations will always be shown in fractions. If decimal
inches are chosen, only the air space thickness and overall IG unit thickness will be shown in decimal inches.
Next, choose your ACTUAL setting. If this setting is activated, your meter will display actual dimensions without rounding. If
your dimensions are set to inches, you will have the options: FRACTION, DECIMAL or OFF. If your dimensions are set to
millimeters, you will have the options: ON or OFF. Touch the back of the meter to find your desired setting and push the button
to select it.
NOTE: STANDARD and ACTUAL cannot both be set to OFF. If they are both activated, the measurements will alternate on the
screen after a measurement has been taken. For an illustration of this feature, see the “Measurement Examples” section.

Proper Operation of the Glass-Chek PRO Page 3
Place the meter on the window to be tested. Press and release the button to turn the meter on and take a measurement.
As the initial message (below at left) is displayed, the meter is already taking a reading. Do not hold the button down, as
this will cause you to enter setup mode.
In all other instances, the meter will indicate it is taking a reading with the
“TAKING READING” message displayed at right. The “TAKING READING”
screen also indicates the amount of voltage remaining in your battery.
Continuing to hold the button down at this time will turn the meter off.
Turning The Meter Off
Hold the button down for several seconds to turn off the meter. A message will display on the screen notifying you that the
meter is about to power down. Continue holding the button down until the screen goes blank. If the meter is left unused
for a period of time, the unit will automatically shut off. To conserve battery life, it is recommended to turn the meter off
manually when you are finished using it.
Guidelines For Most Accurate Results:
•Hold the meter steady and flat against the test surface during measurement
•Do not touch the glass with your hand while taking the reading
•Take readings at the bottom center of the window for best thickness
accuracy (see explanation below)
•Take multiple readings to verify results
•Make sure the window being measured is clean
•Make sure the two lenses on the back of the GC3000 are clean
Use only clean compressed air to clean the lenses. Only use a lint
free cloth if absolutely necessary to clean smudges, fingerprints, etc.
•Make sure nothing is touching the far side surface of the window during the
reading
•It is best to test windows in free air (not resting on a tabletop surface)

HOLD BUTTON FOR MENU
At Right: Incorrect placement for accurate results.
• DO NOT hold the button down while taking a measurement. This will cause
the meter to turn off. Rest your index finger next to the button as shown above.
• DO NOT touch the glass with your hand while taking readings. The picture at
right shows the user’s thumb resting on the window while taking a reading. This
could cause incorrect results for the low-E measurement.
4 OPTIMAL TEST LOCATIONS FOR MOST ACCURATE RESULTS
At Left: Recommended placement of meter:
• Hold the meter steady AND FLAT against the glass during measurement.
• The meter should be centered on one of the four edges of the window with the
bottom edge of the meter placed parallel to the edge of the window (please see
the image to the left). This will minimize the effect of a concave window. As you
move away from the edge of a window, many windows will bow inward (concave).
Because the sensor runs parallel to the bottom edge of the meter, it is important to
place the bottom edge of the meter along the edge of the window as shown.
• DO NOT touch the glass with your hand while taking readings. Note the hand
placement used in the picture at left. The user’s thumb is resting on the GC3000
without touching the glass being measured. Also, be sure there are no other
metallic objects touching the glass
• DO NOT hold down the button while taking a reading.
• Place your index finger next to the button as shown at left.

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. 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 meter did not detect a low-E coating on
pane 1 or pane 2. Since the GC3000 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 low-E.
Display 1 shows the actual dimensions of the window in millimeters. Since the “Standard”
setting is set to OFF, the standard dimensions are not displayed. The word “FILM” indicates
suspended film between the two panes of glass. Display 2 indicates both panes of glass are
“CLEAR” of any low-E coating, but there is a suspended film between the panes.
***Note*** On triple pane measurement displays, “G” = Glass and “A” = Air Space
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 or 4. This means that the meter is only indicating that the coating is on the
second pane of glass. To verify the exact location of the coating, the user must test the
window from the opposite side. The meter also indicates the coating is a hard coat low-E.

Error Messages: Explanations:
The Glass-Chek PRO uses a light/laser beam to measure the thickness
of the glass and air space. The unit may be affected by extremely bright
lights or facing the sun directly. The screen will display this error
message if this condition occurs. Simply move to a different location,
go to the other side of the window, or shade the laser aperture. If the
window is operable you may be able open the window and reach
through the opening to block the incident light from the back side of the
meter.
This error message indicates that your application is most likely out of the maximum thickness range
for low-E measurement. See the “Specifications” section of this manual for more details on the
GC3000’s maximum thickness ranges.
On rare occasions, the user settings (determined in setup mode) will reset to the factory default.
Follow the directions on Page 1: “Using Setup Mode” to re-select your user settings.
This message means your Glass-Chek PRO must be re-calibrated. Please contact us prior to
sending your meter for re-calibration to receive a RMA# (Return Merchandise Auhtorization).
International Users: When returning equipment for repair, recalibration, or simply returning
product, the customer must clearly state on the commercial invoice that the product is being returned
for repair. The commercial invoice must also clearly state that the invoice is for "CUSTOMS
PURPOSES ONLY", and that the goods have "NO COMMERCIAL VALUE". If you must put a commercial value on the
products, place $1 or $10 value on it so there will be no customs impact. Please note that EDTM will not be responsible
for any customs or government processing fees. Any amount that EDTM is charged for receiving the goods, will be added
to the cost of the repair.
Battery and replacement: The GC3000 meter is powered by a 9-volt alkaline battery. When the
battery is starting to get low, an error message will appear that recommends replacing the battery soon.
This gives the user plenty of warning that a battery replacement is needed, and the meter will still function
for a period after this initial warning. Once the battery voltage gets below a dangerous level that could
impact the performance of the instrument, an error message appears that tells you to replace the battery
immediately. The instrument will NOT be able to take measurements once it reaches this level.
Please remember to ALWAYS replace the battery with a 9-volt ALKALINE battery.
UNABLE TO TAKE
READING
If you are having difficulty obtaining an accurate reading, please follow the corrective action steps
outlined in the Troubleshooting Guide on Page 6.
Important Safety Consideration:
The GLASS-CHEK family of glass thickness and air space meters use a Class 2M
laser to take its measurements. Do NOT push the power button and point the
instrument laser at a persons’ eyes. Always check the other side of the window
being tested to ensure that no one will be looking directly into the laser.

Troubleshooting Guide Page 6
If you are having difficulty obtaining an accurate reading, please follow these steps:
1)
manual.
2) Ensure that the Glass-Chek PRO is placed flat against the glass surface and that you are testing
at one of the four optimal locations detailed on Page 3. The meter must be used with the surface
opposite the Power button against the window. Using the small end surface of the unit or tilting the
unit away from the surface will give improper results.
3) Clean the glass surface or move to a cleaner area of the glass.
4) Remove dust particles from the two lenses on the back of the Glass-Chek PRO.
To clean the lenses: WE STRONGLY RECOMMEND USING CLEAN COMPRESSED AIR ONLY TO
CLEAN THE LENSES. However, if there are fingerprints or other smudge marks on the lenses that can
not be removed in any other way, a lint free cloth can be used to wipe off the smudges.
5) Check that the two window surfaces are relatively parallel to each other and the Glass-Chek PRO unit.
6) If only a partial reading occurs, move to another location on the glass or take a reading from the other side.
7) Be sure nothing is touching the glass while taking readings. Placing your hand or a metallic object against the lite of
glass you are testing may cause the Glass-Chek PRO to yield improper Low E results. Remove your hand or object. Do
not touch any part of the glass with your hand while taking readings.
8) Verify the operating temperature range
For operating in cold temperatures:
1) Keep the unit in a warmer environment until you are ready to take the readings. The meter will record accurate
readings until the point the electronics reach the temperature below the operating range. Depending on the degree of
coldness, this will allow for several readings to be taken.
2) Carry the meter in your pocket or in some other manner which will keep the unit near a warmer temp.
3) When temperature is only slightly below the temperature range, operate the unit several times repeatedly in attempt to
warm up the laser.
For operating in hot temperatures:
Keep the unit in a cooler environment until you are ready to take the readings. The meter will record accurate readings
until the point the electronics reach the temperature above the operating range. Depending on the degree of heat, this will
allow for several readings to be taken.
If measurements seem to take a long time:
The amount of time it takes the GC3000 to complete a measurement will vary by application. This does not mean your
meter is defective, it simply takes varying amounts of time depending on the application. Be sure to hold the meter steady
against the window until the results are displayed.
Be sure you are following the guidelines for most accurate results outlined on Page 3 of this

Glass-Chek PRO Application Details Page 7
Will Test:
• Flat glass applications
• Clear glass or glass with low-E coatings, self-clean coatings or other specialty coatings as long
as the glass/coating is transparent
• Laminated glass with low-E coatings positioned against the laminate (see page 9)
• Tinted glass as long as it has a visible light transmission value of approximately 35% or above
Will Not Test:
• Glass coated with reflective (mirror-like) coatings
• Tinted glass with visible light transmission value at approximately 35% or below
Double Pane Windows
The GC3000 will specify if the coating is located on Surface 1,
Surface 2, or Surface 3or4. By moving to the other side of the
window, the meter can differentiate between surface 3 and 4.
Triple Pane Windows
The GC3000 will specify if the coating is located on Surface 1,
Surface 2, or Surface 3or4. By moving to the other side of the
window, the meter can specify Surface 5 and Surface 6. The
GC3000 detects the presence of low-E coatings on the inner
pane of a triple pane unit, but it will not specify which surface the
coating is on. If there are multiple low-E coatings, the GC3000
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 previously 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.
The GC3000 detects the presence and location of low-E coatings on the following applications:
PANE 1 PANE 2

Identifying the type of low-E:
In addition to identifying the location of low-E coatings, the GC3000 determines the type of low-E on your glass application.
The meter will specify it as “hard coat” or “soft coat.” If 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. Here are some examples:
SOFT COAT (sputtered)
Triple Silver Double Silver Single Silver
-Cardinal 366 -Cardinal 270 & 272 -Cardinal 179 -Pilkington Energy Advantage
-PPG SolarBan 70 -PPG SolarBan 60 -PPG Sungate 100 -PPG Sungate 500

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.
