6.4.2 Auto Power Off
If no key operation is given or no process of measurement is performed for more than 30 minutes (No
change exceeding 30” has occurred during horizontal angle or vertical angle measurement.), the power
turns off automatically. If the instrument is set at distance measurement mode (No change in distance
exceeding 10cm has occurred during distance measurement), the mode changes to angle
measurement automatically in case that the instrument does not operate for approximately 10 minutes,
and the power turns off after 20 minutes.
6.4.3 Vertical and Horizontal Angle Tilt correction (Tilt ON/OFF)
(GTS-239N has vertical angle tilt correction only.)
In case the instrument is used in an unstable situation, constant indexing of vertical and horizontal
angle may be impossible. In this case, the function of tilt correction can be stopped by selecting TILT
OFF. It has been set to X, Y (V/H) TILT ON at the factory.
