Leveling method and leveling device

A leveling method in a device main unit with tilt sensors, wherein said method comprises a step of obtaining a response delay of said tilt sensors in advance, a step of tilting said device main unit in a first direction so that said tilt sensors detect a first 0 point, a step of tilting said device...

Beschreibung
Zusammenfassung:	A leveling method in a device main unit with tilt sensors, wherein said method comprises a step of obtaining a response delay of said tilt sensors in advance, a step of tilting said device main unit in a first direction so that said tilt sensors detect a first 0 point, a step of tilting said device main unit in a second direction reverse to said first direction so that a second 0 point is detected after said first 0 point has been detected, a step of obtaining a time up to the detection of both 0 points, a step of calculating a driving time to tilt in the first direction further from said second direction based on said time and said response delay, a step of tilting said device main unit for the driving time, a step of maintaining tilting condition for a predetermined time after tilting and a step of converging by performing leveling operation based on detection result of said tilt sensors after the predetermined time passing.
