1 NOMENCLATURE AND FUNCTIONS
1.6 Auto Power Off
The Auto Power OFF feature can be set from 1 to 99 minutes. If no keys are pressed within the set
time, the Auto Power OFF will automatically turn the instrument OFF in order to save the battery time.
See Chapter 8 “PARAMETERS SETTING MODE”, for further instructions.
1.7 Data Output
When GTS-820A series receives data output command from an external connected
device, the measured data will be output by GTS-820A series. Select from the following
2 ways for the output. (For setting, see Chapter 8 “PARAMETERS SETTING MODE” .)
REC-A : The measurement is started and new data is output.
REC-B : The data being displayed is output.
1.8 Rotating Method
1.8.1 Rotating by H/V Shuttle and H/V Jog
H/V shuttle or H/V jog can be used to rotate the instrument manually. The shuttle movement or
displacement is proportional in speed and size of angle desired. A small, slow turn of the shuttle will
result in a slow small angle displaced. Likewise, a larger abrupt turn of the shuttle will result in a coarse
angle displacement. H/V jog can be used for accurate collimating of the target much like a standard
tangent screw.
1.8.2 Auto Inversion
Pressing the [F4] key in Star Key mode causes the instrument to reverse and turn the telescope and
instrument automatically.
l To stop auto rotating by auto inversion key in case of emergency, press any keys except POWER
key.
l During auto rotation, don't disturb the instrument.(Stopping the rotation with a touch of the hand).
Such action may cause trouble or harm to instrument or operator.
See Section 1.5 “Star key (*key) mode” for further instructions.
1.8.3 Rotating automatically to a required Horizontal and Vertical angle
In Standard Measurement Modes, the instrument can be rotated automatically by input a required
horizontal and/or vertical angle.
For further instructions, see Section 4.1.5 “Automatic Rotation to a Required Horizontal and Vertical
Absolute Angle” .
This mark will appear while the
instrument is rotating automatically.
