12. MEASUREMENT WITH AUTO TRACKING
With the Auto Tracking function, an SRX, sighted on the target using Auto Pointing, will following that
target as it is moved from measurement point to measurmeent point. The On-demand Remote Control
System is recommended for high performance Auto Tracking measurement.

Caution
• The instrument emits a laser beam during Auto Pointing and Auto Tracking operation.

• Auto Pointing can only be performed when a prism is used as the target. Auto Tracking is not
possible with reflective sheet and reflectorless measurement
• Use reflective prisms from Sokkia for higher precision measurement.
• If more than one prism is located in the field of sight during Auto Tracking, an operation error will
occur and the SRX will not be able to find the target.
• The prism beyond the glass can not be searched because measurement error occurs.
• If an obstacle blocks the laser beam path between the SRX and the prism, SRX cannot find the
target correctly.
• Position the prism in alignment with the objective lens. In short distance measurement especially,
make sure to align the prism with the objective lens (within 10 to 15°) to obtain the correct result. A
prism with a prism constant of -40mm can eliminate the error caused by tilted prism.
