Results

Compare the readings. If the two readings are the same, the instrument is in proper adjustment.

If the readings are different, the line of sight should be adjusted so both readings become the same. The crosshairs are actually adjusted. This is a simple procedure and can be performed by anyone with mechanical skill. Before making any adjustment, be sure to triple test the above procedure to confirm the results.

Quick-Peg By One Person

Pegging an instrument doesn’t have to be a time-consuming burden. With a little plan-ning, it can be performed by one person in about one minute. This can be set up to be performed at the home office or at any project site. Here is what to do in a few steps.

Procedure

Locate two objects that are about 250 feet apart where it would be possible to glue onto or nail into a 2-foot or 1-meter section of an old rod. This could be old power poles, light poles, buildings, bridge piers, etc. Obtain permission to do this from the owner.

Set up the leveling instrument exactly between these two objects, make sure it is level, and sight towards each object and mark the line of sight on the object. Because of the geometry of the instrument, these marks will be the same elevation.
