4. USER S MANUAL I Overview of the application This application is designed for measurement of vertical glazing in windows The measure uses the backlight of the display of the iPhone You must insure your iPhone is set to the highest brightness settings and brightness for optimum results The measures in sunlight may thus be difficult or impossible It is therefore advisable to make his first steps indoors or in the evening The user must stand with the strongest light behind him lf the glass to be measured is directly exposed to sunlight open a movable part of the window to make the measure sunlight protected on the movable part wide open or folded against the wall You can measure the glass thickness from inside the glass with sunlight outside in front of you but you must place a dark material on the outer surface of the glass a dark agenda or conference folder as a background behind the glass to protect the screen of the iPhone from direct light Il Main screen of the Apps The main screen presents to you three choices dJe PRISM VER glass thickness measurement Glass Low E rr Air gap thickness measurement thickness layer Low Emissivity layer detection Air gap Converter rr And a scroll millimeter inches converter _ thickness mm inch Select one of these tasks A start screen comes lll Start screen of the task The start screen gives you the following informations 1 two
