ิิby measuring the distances between the target point and the two offset points.
Install two offset points (1st target and 2nd target) on a straight line from the target point, observe the
1st target and 2nd target, then enter the distance between the 2nd target and the target point to find the target point.
• It is possible to make this measurement easily using the optional equipment: the 2-point target
(2RT500-K). When using this 2-point target, be sure to set prism constant to 0.
