Builder, Theodolite Mode
Field Description

The current vertical angle with Zenith=0° and Horizon=90°.
V
The current vertical angle with Zenith=90° and Horizon=0°.
V
V % The current vertical angle in percentage.
Thanks to dual axis compensation, the Builder is able to
adjust the horizontal angle reading accordingly. Therefore,
turning the telescope vertically might cause the horizontal
angle to change. The change in <Hz:> is the compensation
of the standing axis tilt. The more precise the instrument
is leveled, the less the horizontal angle needs to be
compensated.
