Two-Distance Offset Measurement - Sokkia 30R Series Operator's Manual

17.3

Two-distance Offset Measurement

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.
"24.1 Changing Instrument Options
How to use 2-point target (2RT500-K)
• Install the 2-point target with its tip at the target point.
• Face the targets toward the instrument.
• Measure the distance from the target point to the 2nd target.
• Set the reflector type to "sheet".
