13.COORDINATE MEASUREMENT
It is possible to set from the instrument station data to the backsight angle in a series of procedures.
• When performing measurement in which the reduced data is output, be sure to record the instrument station
data before the measurement. If a correct instrument station data is not recorded, it may cause output of an
unintended measurement result.
Reduced data : "31.1 Outputting JOB Data to Host Computer"
Before coordinate measurement, enter instrument station coordinates, the instrument height, target height, and
azimuth angle.
PROCEDURE
1. First measure the target height and instrument height with a
tape measure, etc.
2. Select the calculation program from the Observation menu.
(The explanation below is an example of when "coordinate
measurement" is selected.)

PROCEDURE Reading in Registered Coordinate Data
• Calculating data by resection measurement

• Inputting the backsight angle
"13.1 Entering Instrument Station Data and Azimuth Angle" Step 3
• Calculating from the backsight coordinate
"13.1 Entering Instrument Station Data and Azimuth Angle" Step 3
• Calculating the direction angle by assuming the known point (first point) at the time of
resection measurement as the backsight point.
