MENu OPTIONs (CONT.)
After the WELCOME sCREEN, the meter will go to its measurement reminder screen, reminding you to
place the GC3001
meter at the bottom center of the window for ALL MEAsuREMENTs, approximately 1 to 2 inches up from the frame/sash

This is the preferred measurement location that should be used for ALL MEAsuREMENTs. Testing in this location will
eliminate effects from glass that is flexing inward, resulting in a concave glass surface. The most accurate measurements
of a window will be obtained in this location when using the GC3001 meter.

system any time the meter is powered on by pressing and holding one of the ARROW buttons. Please note that you may
need to hold the ARROW button down for several seconds before entering the MENu system.
