After measuring, the coordinate will be shown. Press [F4] (YES) to record. Point # and coordinates
will be saved into coordinate data file. The next new point inputting menu displays, point# adding 1
automatically.
File can be input directly, press [F4] (ENT) to confirm.
For Instruction of disk , please refer to
section 14 “Memory management”
.
Press [F2](SRCH), enter the file name directly to launch the required COORD. FILE.
Press [F3](EXIT), Display back to LAYOUTMENU.
Refer to section
6.7 “Method of inputting, alphanumeric characters”.
When the memory room is full, error message will display.

Resection method
Set up the instrument at a new point and calculate the coordinate of the new point using the coordinate
data for maximum seven known points and the measurement made to these points. By following
observation, resection is possible.
•
Resection by distance measurement: 2 or more points must be measured.
•
Resection by angle measurement: 3 or more points must be measured.
•
Resection by angle measurement and distance measurement cannot be used together. When using
resection by angle measurement, the direction of known points should be clockwise or anti-clockwise,
and the angle between two points should not exceed 180.
An occupied point coordinate value will be calculated by the method of least squares. (In case that 3
known points are measured by angle measurement only, the value would not be calculated by the method
of least squares).
