ETS-Lindgren 2175 Antenna Tower - Manual (Page 28)

28 | Operation
If the value is below 1000, the resolution of the encoder is low and the
controller will not provide 0.1 cm resolution, even though the display shows
that digit. If the value has gone past 9999, the encoder has too many counts
per meter and the controller cannot correct for it. In this case, contact
ETS-Lindgren for assistance.
5. Enter this value for the encoder calibration value and reset the limits and
position information.
6. Test the MiniMast by moving it to a known distance and comparing the
display to the measured distance traveled. It may be necessary to adjust
the encoder calibration value up or down slightly depending on the result.
Antenna Mounting Instructions
Antennas may be mounted to the assembly using either the 7/8–14 thread which
is common on ETS-Lindgren brand antennas, or the 1/4–20 thread which is
another common size. The antenna should be mounted on the boom as close to
the carrier as possible. Insert the mounting knobs through the holes on the boom
and align the mounting holes on the antenna with the threaded end of the
mounting knobs. Secure the antenna in place by tightening the threaded knobs
into the receptacle mounting holes on the antenna.
Antennas may also be mounted using the stinger mount adapter included with
the assembly.
