Fine Alignment Vertical Motion Screws – Two screws (‘C’). Used for fine
rotation of the TereScope in the vertical plane.
Fine Alignment Horizontal Motion Screws – Two screws (‘B’). Used for
fine rotation of the TereScope in the horizontal plane..
Note
# Two installers are required for fine alignment, one
at each TereScope site.
# The installers should each have a walkie-talkie, a
mobile phone or any other equipment to enable
each to talk to the other working at the opposite
site.
The fine alignment procedure is as follows:
1. Find the horizontal and vertical Beam edges (H1, H2, V1, V2) by
obtaining a reading between 50 and 80 on the 7-segment display.
(between 250 and 300 for the TS700/G)
2. Set successively the remote transceiver in the middle of the
two segments [H1,H2] and [V1,V2].
H1 H2
V1
V2
Important: Do not in any case select the head position for which the DVM reading
is maximum! The best position of alignment is the beam center.
To determine the horizontal beam edges H1 and H2, move the local transceiver
slowly left and right until the digital readout on the remote transceiver becomes 50.
(250 for the TS700/G) Identify these two points relative to reference points on the
opposite site by looking through the telescope. By moving the local transceiver, set
the remote transceiver at the middle of these two reference points.
