visible simultaneously. In this position, the prism is in the line of sight of the
instr
ument.
1. Check Use the ins
trument guide lights (EGL) in the Instrument
Lights panel.
OR
Set Aim at target: With lock and press Turn to Hz/V in the icons
menu.
2. Align instrument line of sight and prism, where both flashing EGL
lights can be seen simultaneously.
3. OK to lock onto the prism.
4. If the instrument has locked onto the prism the EGL is turned off
automatically.
☞
If the EGL was turned on in Instrument Lights, it must be turned
off by unchecking the check box.
33.6 Illumination
There are several different illumination types built into the instrument that all
fulf
il different functions. Some are to support measurements, for example the
visible red laser pointer. Others, such as the screen illumination, are for more
convenient work with the instrument. These different types of illumination are
described in this chapter.
The laser plummet allows setting up the instrument over a marked point. The
las
er b
eam is emitted from the bottom of the instrument, pointing to the
ground. When the instrument is levelled and the laser beam points exactly at
the ground point, the instrument is set up correctly.
The laser plummet can be turned on and off. It is turned on automatically when
opening Settings\TS instrument\Level & compensator.
The visible red laser pointer is used to measure to any surface. The visible red
laser p
ointer is arranged coaxially with the line of sight of the telescope and
emitted through the objective. If the instrument is correctly adjusted, the visi-
ble red laser beam coincides with the line of sight.
The direction of the beam should be inspected before precise distance meas-
uremen
ts are executed. An excessive deviation of the laser beam from the line
of sight can cause inaccurate results.
