Keeping the Embedded Targets Clean on the Laser Tracker
While the tracker is still turned on, simply track a Spherically Mounted Retroreflector (SMR) to the left or right side of the tracker so the Azimuth (left and right movement) axis is covering the embedded targets.
While the tracker is turned off, the tracker's dust cover can be used to keep these targets clean.
