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.

lTo stop auto rotating by auto inversion key in case of emergency, press any keys except POWER key.

lDuring 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” .

V : 87°55'45"5

HR: 180°44'12"5

This mark will appear while the instrument is rotating automatically.
