MEASURING A SLOPE

1.

Use surveying level to sight target by looking through eye piece (Figure 2, Item 7), aligning cross line

(Figure 2, Item 6) (left side) on the top of the slope if going uphill or the bottom of the slope if going downhill.

2.

While sighting on target with cross line (Figure 2, Item 6), move index arm (Figure 2, Item 3) for coarse

adjustments, or turn setting knob (Figure 2, Item 4) for slow motion adjustment until center level vial bubble

(Figure 2, Item 5) is aligned with the cross line.

3.

Lock index arm (Figure 2, Item 3) by tightening thumb nut (Figure 2, Item 2) if necessary. Read slope

percentage indicated by index arm on scale (Figure 2, Item 1).
