6 SPECIAL MODE (Menu Mode)6.1.4 Area CalculationThis mode calculate the area of a closed figure.There are two area calculation methods as follows.1) Area Calculation from Coordinate data file2) Area Calculation from Measured data●●●●Area is not calculated correctly if enclosed lines cross each other.It is impossible to calculate what a mix of coordinate file data and measured data.If the coordinate data file does not exist, the area calculation from measured data is doneautomatically.The numbers of points used to calculate are not limited.1) Area Calculation from Coordinate Data FileOperating procedure Operation Display1 After pressing the [MENU] key, press the [F4](P↓)key to get the menu on page 2/3.[MENU][F4]MENU 2/3F1:PROGRAMSF2:GRID FACTORF3:ILLUMINATION P↓2 Press the [F1] key.
