Adjusting
There are two steps in the calibration program. Usually you only complete the first
step that is described below, because the trunnion axis is finely adjusted mechanically.
To make a major adjustment to the trunnion axis error compensation, however, you
can complete the second step that is described below and make three sets of
observations.
To enter the calibration program, tap [Windows]
button to display the menu. Select [Program] to
show the sub-menu. Choose [Calibration].
First step
1. Tap [VA0/HA/Tilt], and take an F1
measurement to a target on the horizon.
Tap [OK] button.
The vertical angle is shown in the
V0 dir= Horiz setting.
Note – Auto focus calibration only applies to XF
Series. This menu option is not available for the
XF HP Series.
To set the parameters for trunnion axis error compensation, establish
two targets at a horizontal distance of at least 30 m from the instrument.
The first target should be placed on the horizontal plane and the second
should be more than 30° above the horizontal plane. Before you set the
trunnion axis compensation value, you must complete three sets of
F1/F2 observations to these two points. Even if you complete the
second step, the instrument cannot store a trunnion axis error
compensation of more than 30". If the error is more than 30", the
instrument needs a mechanical check.
