measurement procedure. If the value is greater than
0.05 grads (0.045 degrees) and you answer No to the re
measurement message, the instrument uses the
correction value previously stored in the instrument. If the
value is greater than 0.05 grads (0.045 degrees), then the
instrument must be mechanically adjusted at the nearest
authorized Spectra Geospatial service center.
Autolock Collimation
Autolock® technology collimation check needs to be carried
out on a regular basis (under the same conditions as the HA/VA
collimation check).
Perform the test over a similar distance as that you will be
working on, but at least 100 m. The prism target must be very
still during the test (Spectra Geospatial recommends that you
use a tripod or bi-pod mount for the target) and must be in
clear line of sight without any obstructing traffic. The
instrument is calibrated to accurately point at the center of
the target in both horizontal and vertical axes. The calibration
is used to correct the positions of all points measured using
the Autolock function. The measured calibration values are
stored and used until a new set of calibration values are
determined.
Note - The adjustment between the two optical axes, i.e.
the Telescope and the Tracker, may differ. See Aiming on
page 69.
