4.5.2 Practical zero point search

The LIVE MONITOR mode can be used to find the

reference point (0 mm). This function displays the

LEFT EDGE RISING (the first rising edge from the

left side) of objects. Now an object is slowly pushed

toward the presumed zero point. The zero point is

reached when the value 0 mm is shown on the

sensor display.

NOTE

If the sensor is mounted inclined, FLEX MOUNT has to be activated.
