6. COORDINATE MEASUREMENT
6-7
3) Measuring takes time when the path of laser is disturbed frequently or the weather condition is not
suitable.
4) Press [F4](NO) key when the measurement in inverted position of telescope is not required,the
procedure goes to step
15
.
5) Error message will be displayed when the vertical angle error or horizontal angle discrepancy is
exceeded 60", and returns to the procedure
automatically.
Vertical angle error (dVA) of the known point A
dVA = [Measured value in normal position] + [Measured value in inverted
position] 360 (at zenith)
Vertical angle error (dVB) of the known point B
dVB = [Measured value in normal position] + [Measured value in inverted
position] 360 (at zenith)
Horizontal angle discrepancy (dH)
dH = [Measured angle value between 2points in normal position]
[Measured angle value between 2point in inverted position]
6) When [F3](NO) key is pressed,the procedure returns to step
.
7) Error will be displayed when the angle of dHD or dZ is exceeded 999mm, and the display
changes to select for remeasurement. Press [F3](YES) key to select remeasurement and start
from the procedure
.
Horizontal distance discrepancy (dHD)
dHD = [Horizontal distance between known point A and B based on
measured value] [Horizontal distance between known point A and
B based on inputted coordinate value of known point A and B]
Z coordinate discrepancy (dZ)
dZ = [Z coordinate value of the instrument calculated from measured value
of known point A] [Z coordinate value of the instrument calculated
from measured value of known point B]
In selecting 2 Dimensional measurement, Z coordinate discrepancy (dZ) will not be
displayed.
8) The screen displays selecting for remeasurement when [F4](NO) keys is pressed. Press
[F3](YES) key to start remeasurement and returns to the procedure
.
9) In selecting 2 Dimensional measurement, N and E coordinate only will be set newly.
Press [ESC] key or [F1](EXIT) key to cancel the setting mode on the way.
