INITIALISATION EXAMPLE
12:00 VIEWING ANGLE, TOP VIEW OPTION
If the display is read mostly from above (on the front of a laboratory power supply unit, for example), the preferred
angle of viewing can be set to 12 o’clock. This rotaties the display by 180°. A slightly different initialization setup is
required for this. Also keep in mind that the leftmost column (normally numbered as 0) will now change to 30.
*) Make sure that for 6:00 viewing direction SEG has to be set to „reverse“ (mirrored layout) !
