3.4  Chart positioning  

Please note that the placement of chart type (A), (B), or (C) in the following description is vital and must 

not be changed. Otherwise, the automatic detection of the iQ-Analyzer-X will not work. You may also 

have to optimize your camera position while positioning your charts. 

Setup 1: 

Place chart (C) in the center of the back wall. The other charts must be positioned on a straight vertical 

and horizontal line through the image center. The vertical placement has to have one chart (A) on the 

top  using  the  top  wall  and  one  chart  (B)  at  the  bottom  using  the  bottom  floor  wall.  The  horizontal 

placement has to be done similarly: place one chart (B) on the left wall and one chart (A) on the right 

wall. Use folding and rotating for each chart so that its border looks straight-lined in the resulting image:
