   7 DATA COLLECTION

7-17

As measured data is collected, coordinates are calculated and stored for traverse or topo collection.  
Automatic making out function of coordinate data sets up in CONFIG of data collect. Refer to Section 
7.6 “Setting Parameter of Data Collect [CONFIG.]”.
As a default, coordinate data calculated will be saved in a file of the same name as the measurement 
data file.
When the coordinate data file of the same name as the measurement data file does not exist, it will be 
generated automatically.
It is possible to change a file for saving coordinate data in the DATA COLLECT Menu 2/2 (F1:SELECT 
A FILE).
To calculate a coordinate data, it is necessary to add a point number  in Data Collect execution.
When a coordinate data of the same point number exist already, it can be replaced with the new data by 
confirming display.
