A Dakshinottara Bhitti Yantra consists of a graduated quadrant or a semicircle inscribed on a north-south wall. At the center of athe arc is a horizontal rod. The insrument is used for measuring the meridian altitude or the zenith distance of an object such as the sun, the moon, or a planet. This is a modified version of the meridian dial of the ancients, which was a portable instrument. With this instrument, the meridian altitude of the sun is discerned from the shadow of the rod cast by the sun on the instument scale at noon on a clear day.
