4 STANDARD MEASUREMENT MODE

4.3 COORDINATE MEASUREMENT

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” .
