Target Residuals The Target Residuals screen displays the computed residuals for the horizontal and
vertical distances and the horizontal direction. Residual = Calculated value - Measured
value.
Use indicates if and how a target point is used in the station calculation. Choices are
3D, 2D, 1D and Off.

• If a target point is measured several times in the same face, only the last valid meas-
urement is used for computation.
•For Method: Resection:
• The prism used for face I and face II measurements must be the same.
• If different codes for face I and II are used, then the code of face I is used. If only
face II is measured with a code, then the code of face II is assigned to the point.
• XML output does not allow a change of the ppm value during Stn.Setup measure-
ments.
• If the scale is calculated, then the standard deviation of the position with two targets
is 0.0000. With flexible scale, the resection is fitted perfectly into the geometry
without redundancy. Therefore the standard deviation is 0.000.
Apply Scale Yes or No. Select Yes to use the calculated scale as the system PPM
scale. This overwrites any PPM scale previously set in the EDM Settings
screens. Select No to keep the existing PPM value in the system and not
apply the calculated scale.
Field Description
Field Description
3D Easting, Northing and Height coordinates are used for the calculation.
2D Easting and Northing coordinates are used for the calculation.
1D Only the height of the point is used for the calculation.
Off The point is not used for the calculation.
Messages Description
Selected point has
invalid data! Check
data and try again!
This message occurs if the selected target point has no
Easting or Northing coordinate.
Max. 10 points
supported!
10 points have already been measured and another point is
selected. The system supports a maximum of 10 points.
No position computed
due to bad data!
The measurements may not allow final station coordinates
(Eastings, Northings) to be computed.
No height computed
due to bad data!
Either the target height is invalid or insufficient measure-
ments are available to compute a final station height.
Face I/II mismatch! This error occurs if a point was measured in one face and the
measurement in the other face differs by more than the spec-
ified accuracy limit for the horizontal or vertical angle.
No data measured!
Measure point again!
There is insufficient data measured to be able to compute a
position or height. Either there are not enough points used or
no distance measured.
