10.10 PARALLEL BETWEEN LINE OF SIGHT AND EMITTING PHOTOELECTRIC AXIS
Check
1. Set the reflector 50m away from the instrument.
2. Collimate the center of the reflector prism with reticle.
3. Switch on the instrument, and enter into Distance Measurement Mode. Press
DIST (or All) to measure. Rotate the Horizontal Tangent Screw and Vertical
Tangent Screw to launch electric collimation and make the light path of EDM
unblocked. In the bright zone find the center of emitting photoelectric axis.
4. Check the center of reticle to coincide with the center of emitting photoelectric
axis. If so, the instrument is proved eligible.
Adjust
If the center of reticle deviates from the center of emitting photoelectric axis, user
should sent the instrument to professional repair department.
10.11 REFLECTORLESS EDM
The red laser beam used for measuring without reflector is arranged coaxially
with the line of sight of the telescope, and emerges from the objective port. If the
instrument is well adjusted, the red measuring beam will coincide with the visual
line of sight. External influences such as shock or large temperature fluctuations
can displace the red measuring beam relative to the line of sight.
● The direction of the beam should be inspected before precise measurement of
distances, because an excessive deviation of the laser beam from the line of
sight can result in imprecise distance measurements.
Warning
Looking straight at the laser beam should be always considered as hazardous.
Precautions:
Do not stare into the beam or direct it towards other people unnecessarily. These
measures are also valid for the reflected beam.
Inspection:
A target plate is provided. Set it up between five and 20 meters away with the
grey reflective side facing the instrument. Move the telescope to face II. Switch
on the red laser beam by activating the laser-point function. Use the telescope
crosshair to align the instrument with the centre of the target plate, and then
inspect the position of the red laser dot on the target plate. Generally speaking
the red spot cannot be seen through the telescope, so look at the target plate
from just above the telescope or from just to the side of it.
