    DS2 Ethernet Instruction Manual 5. FUNCTIONING MODES The DS2 light grids detect and measure objects placed inside the detection area. Hence, beam interruptions can cause the switching of the digital output and the variation of the analogue output signal. Small objects (up to 12 mm) detection and geometrical measurements determined with approximately 6 mm resolution can be obtained by setting the device according to the different functioning modes.
