Setting of tilt correction on vertical and horizontal angles
When activating the tilt sensor, it will show the correction value of vertical and horizontal angles because
the instrument is not perfectly leveled. To ensure the measurement accuracy, the tilt sensor should be
activated (single/dual axis), which will facilitate you to level the instrument better. When the tilt sensor
interface appears, it needs to be leveled manually.
•
The CTS-112R series can automatically correct the horizontal and vertical angle readings deviations
which are caused by tilt of instrument’s vertical axis on X and Y direction.
•
The CTS-112R series provide 3 tilt correction modes: disable tilt sensor, X-ON (single axis) and XYON
(dual axis). Dual axis compensation: correct the errors of horizontal angle caused by the index error
of vertical angle and tilt of vertical axis. When it exceeds the limit, the tilt sensor interface will
appear. User should level the instrument manually. Single axis compensation: correct the index error
of vertical angle. When it exceeds the correction limit of vertical angle, the tilt sensor interface will
appear.
•
Disable tilt sensor: close the tilt compensator.
If the instrument operates under an unstable status or windy days, the vertical angle displays unstably. In
such circumstances, the tilt sensor should be disabled, so that it will avoid the instrument from
displaying error messages as well as abortion of measurement caused by the tilt sensor exceeding the
correction limit.
