Leica 1000Z01 user manual 287

Measure to the current position of the prism pole.

The value for "ΔXS Hgt Diff" needs to be zero or close to it. When this value is zero the catch point has been determined. However, the value for "ΔChainage" is also important. This value shows where the actual point is in relation to the chainage of the cross section being used.

In the sample display shown, the value for "ΔXS Hgt Diff" is 1.089 m. The value is positive which means the catch point is higher than where the measurement was taken. Therefore the rodperson would look for a spot that is approximately 1 m higher than the current point.

Now look at the value for "ΔChainage". This indicates where the prism pole is in relation to the chainage. In this example, the rodperson would move approximately 3 m to his/her right looking towards the instrument. If the value is negative the pole would be moved to the left.

In addition, the horizontal distance from centerline is displayed which is 9.867 m for this example.

After moving to a new location, measure a distance to the prism and view the results. When the "ΔXS Hgt Diff" and "ΔStation" are at or near zero the catch point has been located both vertically and horizontally for the chosen chainage.

Record the staked out position.

The "SLOPE STAKING" display returns and another catch point can be staked.

Exit the slope staking program.
