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.
