1. If considering the effect of grid scale you should
▲
select menu item 1,else you should select menu
item 2;
2. Select one of two modes
▲
3. Press F1:【Meas】to start EDM then you can
obtain the coordinates of the base point, or Press F3:
【Coor.】then you can call an existing coordinate
m
from current coordinate file.
4. the data of the base point is shown as the picture
on the left.
4.827m
5. Press F1:【Meas】to start EDM then you can
obtain next coordinates, or Press F3:【Coor.】then
you can call an existing coordinate from current
5.458m
coordinate file.
6. There are Dsd（slope distance）,Dhd（horizontal
1.343
distance）,Dvd（difference of height）and azimuth
1.297
attributes between two points. these attributes are
0.347
shown as the picture on the left.
