Set up the tilt correction of horizontal and vertical angles
When the tilt (inclination) sensor is on, the instrument will display the automatic
correction value for the vertical angle. In order to ensure the accuracy of the angle
measurement, try to use tilt sensor to level the instrument better.
If the display shows ‘Tilt over’ in the ‘Vz’ column, this is an indication that
the instrument is beyond the range of the automatic compensation, it needs to be
leveled by the adjusting foot screw.
The ATS-120B series Total Station can correct the vertical angle
readings caused by the tilt of vertical axis in the X direction.
The compensator has two states: on and off.++++
If in an unstable environment, or on a windy day, it is advisable to close the
compensator. This is to avoid mismeasurements.You can turn off the
compensator by the using star key (
★
) functions.

Set up the target Type
There are three reflector options: prism, non-prism and reflector board.
The ATS-120B, however, has only two: prism and reflector board. Set up the
necessary options with the star key (
★
) .
3.4.
Set up the Reflecting Prism Constant.
As a prism is selected as a reflector, a prism constant should be set before
any measurement. If the constant is entered and set, it is saved and will not be
erased after switching off the instrument. After pressing ‘parameters’ key under
star key (
★
) mode, a dialog box will appear as follows.
Press the “Enter” key to move the inserter down to the ‘Para.’
3.5.
Signal
The function of the signal is to display the intensity of the EDM (Electrical
Distance Measurement). It can help achieve ideal aiming results under poor
conditions. The signal makes it easier to aim towards the target. Proceeding from the
operation in
3.4,
press ‘Signal’. The intensity of the signal is displayed in the
‘Signal’ column above. The minimum measurable intensity should be 1.
