SELECTING UNIT OF MEASURE:
The GC3001 can display thickness measurements in various units. You also have the option of rounding measurements
to the nearest “Glass Thickness Standard” (Refer to GC3001 Glass Standards chart on page 19). To choose the display units
appropriate for your application, follow these steps:
In the MENU, select the “DISPLAY UNITS” option. The sub-menu to the right will be displayed:
First, select the “DIMENSIONS” option by pressing the POWER button. Choose if you want your unit of measure to be
millimeters or inches. Use the ARROW keys to toggle between units and press the POWER button to make your selection.
Next, determine whether you want the meter to: 1.) round measurements to the nearest Glass STANDARD, 2.) display the
ACTUAL glass thickness dimensions or 3.) display both STANDARD and ACTUAL. 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. Use the ARROW button to find your
desired setting and press the POWER 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. The glass thickness will always be shown in fractions of an inch
when STANDARD is turned on.
Next, choose your ACTUAL setting. If this setting is activated, your meter will display actual glass thickness 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. Use the ARROW buttons to find your desired
setting and press the POWER 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.

MODE APPLICATIONS
1. NORMAL GLASS
This is the default operating mode. NORMAL GLASS MODE will be used for the majority of all
measurements. This mode will test single, double and triple pane (IG) windows. If you use this
mode to test laminated glass, the meter will display the overall thickness of the laminated glass,
but not identify It as laminated glass nor provide details about the Inner-layer thickness. You will
need to upgrade to the GC3200 Glass-Chek ELITE if you want to test laminated glass.
2. LAMI + LOW E
Select this MODE if you are tasting a laminated piece of glass that has a Low E coating placed
against the laminate inner layer (Surface 2 or3). This MODE will estimate the thickness of both
pieces of glass in the assembly, and also identify if the Low E coating is on Surface 2 versus
Surface 3. PLEASE NOTE: ONLY USE THIS MODE WHEN THE LOW E COATING IS PLACED
AGAINST THE LAMINATE INNER LAYER. USING THIS MODE ON ANY OTHER GLASS
COULD CAUSE ERRORS IN YOUR MEASUREMENT RESULTS.
3. SUSPENDED FILM
If you encounter a window that has film (polyester) suspended between the panes of glass, use
this MODE to measure the glass and multiple air spaces that occur in the window. In this MODE,
the meter will only test the nearest pane of glass for low e coatings. This MODE will only test for
1 piece of suspended film in the air space of the window. Testing regular windows in this MODE
will cause an error.

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 (see image
to the left). BOTTOM CENTER IS THE PREFERRED LOCATION. This will
minimize the effect of a concave (or collapsed) 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. You can place the meter approximately 1 to 2 inches from the edge
of the window.
DO NOT touch the glass with your hand or thumb while taking measurements.
Note the hand placement used in the picture at left. The user’s thumb is
resting on the GC3200 without touching the glass being measured. Also, be
sure there are no other metallic objects touching the glass.

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).

APPLICATION EXAMPLES (CONT.)
The next screens will show the make-up of the laminated Low E piece of glass by Itself. The meter has been designed to
add the thickness of the LAM I layer to the thickness of the glass that contains NO low-E coating. For the Low E piece of
glass, the meter will display the actual thickness of the glass itself. Therefore the piece of glass that is displayed as a “nor-
mal” standard thickness (0.128” or 1/8” for example) Is the pane that has the low-E coating on it. This means that the piece
of glass that has an abnormal (larger) glass thickness (caused by adding the LAM I thickness to the glass thickness) will be
the glass pane that is clear of any Low E coating. In the example the clear glass + lami = . 159’’ or 5/32”.
On screens 2 and 4, you will see that these two thickness values are denoted by the letter ”D” (D1 & D2). Because the
meter does not know which thickness value is the glass, and which one contains the glass+ lami, an arbitrary value of D as-
signed to the thickness values.
Screen 5 takes the evaluation one step further and makes the assumption that both pieces of glass comprising the lam-
inated piece are the same thickness (G1 + G2). This Is called the ASSUMPTION SCREEN. If G1 = G2 for your application,
then Screen 5 will show the glass thickness, the laminate inner-layer thickness, and it will also confirm that the low e coating
is on Surface 2 versus Surface 3. You will also notice on Screen 5, the meter actually identifies SURFACE 2 as the Low E
surface in this example.
The final Screen 6 in the sequence confirms the presence of the Low E Coating against the laminate inner-layer, and also
indicates the type of low E coating.

LOWE 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 PRO 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 GC3001 detects the presence and
location of low-E coatings on the following applications:
SEPTEMBER 2020
DOUBLE PANE WINDOWS
The GC3001 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 GC3001 will specify if the coating is located on
Surface 1 or Surface 2 of a single piece of glass.

LOWE DETECTION CAPABILITIES (CONT.)
IDENTIFYING THE TYPE OF LOWE
In addition to identifying the location of low-E coatings, the GC3001 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 GC3001 meter that lists many
of the common Low E coatings used in the USA. Here are some examples.
TRIPLE PANE WINDOWS
The GC3001 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 GC3001 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
GC3001 will only identify the nearest coating.

HELPFUL OPERATING TIPS AND EXPLANATIONS
1. The darker the glass, the longer it will take to complete a measurement
2. If testing dark glass in a window, try to test from the side of the window that contains the clear piece of glass.
3. Always conduct your measurements in the BOTTOM CENTER of the window.
4. Take multiple measurements to confirm your test results, but always test near the bottom center of the window
(either side).
5. If the window has more than one low e coating, the GC3001 will only identify the first (nearest) coating it encounters.

EXPLANATION OF ERROR MESSAGES
ERROR MESSAGES: EXPLANATIONS:
This error indicates a problem with the measurement. Be sure you are following the
guidelines for the most accurate results outlined on Page 5, and attempt to take the
reading again. Make sure the meter is flat against the glass during the measurement,
and do not move the meter during the course of a measurement.
If the window area under test is excessively dirty or contaminated, the Glass-Chek
PRO may give improper thickness or low-E results or issue an error message. The
window area under test must be CLEAN as well as the lenses on the back of the
meter. Clean the lenses on the back of the GC3001 with compressed air. Use a
lint-free cloth if absolutely necessary to clean smudges, fingerprints, etc., as shown
on Page 5.
The Glass-Chek PRO uses a laser 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 on Page 11
of this manual for more details on the GC3001’s maximum thickness ranges.
Battery and replacement:
The GC3001 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 soon, but 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 take measurements once
it reaches this level.
Please remember to ALWAYS replace the battery with a 9-volt ALKALINE battery.

Helpful Operating Tips & Explanations
1. Thin glass will measure the fastest, while thicker glass such as 1/4” will take longer to measure.
2. The darker the glass, the longer it will take to complete a measurement
3. To speed up measurements, switch the OPERATING MODE to NORMAL GLASS (NO LAMI) if you know there is no laminated glass.
4. If testing dark glass in a window or laminated piece, try to test from the side of the window that contains the clear piece of glass.
5. For a reminder of any Low E Coatings, check the drawing at the bottom of the display as the Low E coated surface #’s will be blinking.
6. Always conduct your measurements in the of the window.
7. Take multiple measurements to confirm your test results, but always test near the bottom center of the window (either side).
8. If you do not receive a complete set of results when testing laminated glass or multi-laminate, move to the other side and test again.
9. If the window has more than one low e coating, the GC3200 will only identify the first (nearest) coating it encounters.

TROUBLESHOOTING GUIDE
If you are having difficulty obtaining an accurate measurement, please follow these steps:
1. Be sure you are following the guidelines for most accurate results outlined on Page 5 of
this manual. Make sure you are testing the BOTTOM CENTER of the window.
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 5. 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. If only a partial reading occurs, move to another location on the glass or take a reading from the other side of the window.
Page 10
6. Be sure nothing is touching the glass while taking measurements. Placing your hand or any 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.
7. Verify the operating temperature range
8. If measurements seem to take a long time:
The amount of time it takes the GC3001 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. Measurements that will take longer include: Thick Glass, Dark
Glass
9. For operating in cold temperatures:
a) Keep the unit in a warmer environment until you are ready to take the readings. The meter will record accurate read-
ings until the point the electronics reach the temperature below the operating range. Depending on the degree of cold-
ness, this will allow for several readings to be taken.
b) Carry the meter close to your body or in some other manner that will keep the unit near a warmer temperature.
c) When temperature is only slightly below the temperature range, operate the unit several times repeatedly in attempt
to warm up the laser.
