Proper Operation of the Glass-Chek ELITE
Page 6
Place the meter at the bottom center of the window to be tested. Press
and release
the POWER button to take a measurement. Do not hold
the POWER button down, as this will cause the meter to shut off. The “TAKING READING” message will be displayed while your
measurement is being completed. The “TAKING READING” screen also indicates the remaining battery life, as well as confirms the operating
MODE the meter is in.
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
of the window for best
thickness
accuracy (see explanation below)
• Take multiple measurements to verify results
• Make sure the window being measured is clean
• Make sure the two lenses on the back of the GC3200 are clean. See Image
to the right. -------->
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
measurement
• It is best to test windows in free air, not resting on a tabletop surface, or
stacked on other pieces of glass.
BOTTOM CENTER
Above: Back of GC3200 meter with the two lenses
circled. Use clean compressed air to clean the
lenses.
At Right: Incorrect hand placement.
• DO NOT hold the POWER button 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 measurement.
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 (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.
DO NOT continue to hold down
the button while taking a
measurement.
Place your index finger next to
the button as shown at left.
