3 STANDARD MEASUREMENT MODE
3.4.3 Execution of Coordinate Measuring
Measure the coordinates by entering the instrument height and reflector height, coordinates of
unknown point will be measured directly.
● When setting coordinate values of occupied point, see section 3.4.1“Setting Coordinate Values of
Occupied Point” .
● When setting the instrument height and reflector height, see section 3.4.2“Setting of the Instrument
Height / Reflector(Prism) Height” .
● The coordinates of the unknown point are calculated as shown below and displayed:
Coordinates of occupied point : (N

)
Instrument height : INST.HT
Reflector height : R.HT
Vertical distance(Relative elevation) : z
Coordinates of the center of the reflector,
originated from the center point of the instrument : (n,e,z)
Coordinates of unknown point : (N

Confirm the angle measurement mode.
1 Set coordinates values of occupied point
and instrument/reflector height. *1)
2 Set the direction angle of known point A. *2)
3
Collimate the reflector.
4 Press the [ ] key.
Measuring starts.
*1) In case the coordinate of occupied point is not entered, (0,0,0) will be used as the default for the
occupied point.
The instrument height will be calculated as 0 when the instrument height is not entered.
The reflector height will be calculated as 0 when the reflector height is not set.
*2) Refer to section 3.2.3“Measuring from the Required Horizontal Angle” .
