5 COORDINATE MEASUREMENT
5.4
Execution of Coordinate Measuring
Measure the coordinates by entering the instrument height and prism height, coordinates of unknown
point will be measured directly.
●
When setting coordinate values of occupied point, see Section 5.1 “Setting Coordinate Values of
Occupied Point”
●
When setting the instrument height and prism height, see Section 5.2 “Setting Height of the
Instrument” and 5.3 “Setting Height of Target (Prism Height)”.
●
The coordinates of the unknown point are calculated as shown below and displayed:
Coordinates of occupied point
: (N

Instrument height
: INS.HT
Prism height
: R.HT
Vertical distance (Relative elevation)
: z (VD)
Coordinates of the center of the prism,
originated from the center point of the instrument
: (n,e,z)

*1) Refer to Section 3.3 “Measuring from the Required Horizontal Angle”.
●
In case the coordinate of instrument point is not entered, (0,0,0) will be used as the default for the
instrument point.
The instrument height will be calculated as 0 when the instrument height is not entered.
●
The prism height will be calculated as 0 when the prism height is not set.
