Sensor orientation
The sensor has a marking (arrow symbol on the shaft or glue dot on
connection head). The infrared beam emerges from the front of the
sensor at an angle of 45 ° in the direction opposite the marking.
Fig. 3-2
Direction of the infrared beam relative to the marking
The angle of incidence to the ground and walls can be affected by
rotating the sensor around its longitudinal axis. The sensor should be
turned so that as little light as possible that is scattered or reflected by
the wall or ground strikes the measurement window again.
