Auto stake settings

The Settings form appears when you tap Next in the Auto stake form.

Point details

Specify the Start point and Point code.

Position tolerance

Specify the tolerances for a centerline or grade line.

The Station tolerance value applies forward and back along the line.

The Offset tolerance is defined left and right of the line.

The Grade tolerance is defined up and down from the line and perpendicular to the line.

Settings

EDM timeout

To improve performance, reduce the length of the EDM timeout. If the instrument struggles to get a measurement due to, for example, reflective or dark surfaces, increase the EDM timeout.

Mark delay

The Mark delay is the length of time, in seconds, that the laser pointer flashes once the position is found.

When a position is found within tolerance, the Mark point event sounds and:

• If the instrument has a tracklight, the laser pointer and the tracklight flash for the period defined in the Mark delay field.
• If the instrument is a Trimble SX12 scanning total station, the laser pointer changes to solid and the Target Illumination light (TIL) flashes for the period defined in the Mark delay field.

If a point within tolerance cannot be found, the point is skipped.

Start delay

The Start delay gives you time to walk to the location of the first point to be marked. If the number of Iterations is exceeded, or the EDM times out, the point is skipped.

Measure to define laser line elevation

Select the Measure to define laser line elevation check box when:

• You want to override the elevation of the points used to define the laser line.
• The points defining the laser line have no elevation or have an arbitrary elevation of 0. This can be the case when the laser lines are defined from lines in a DXF file.

If you select the Measure to define laser line elevation check box, you are prompted to take a measurement before the autostake process begins. The measured elevation is then used to define the elevation for the line.
