4.3.1 Setting Coordinate Values of Occupied Point
The occupied point coordinates (NEZ) can be preset in the GTS-820A Series to calculate the unknown
point coordinates. It is possible to retain the occupied coordinates in memory once the power is turned
OFF if the (NEZ mem) is ON in the Parameter Setting Modes. IF (NEZ mem) is OFF in the Parameter
Setting Modes, the occupied coordinates will be retained only if you choose (Resume ON) when
shutting the power OFF.
For instructions on how to select NEZ memory ON/OFF, refer to Chapter 8 “PARAMETERS SETTING
MODE” .
Confirm the angle measurement mode.
