Now, whenever a leveling instrument needs to be pegged, simply set up the instrument close to one of the objects. Sight onto the near rod face, and read the rod. Sight onto the far rod face, and read the rod.
Glue or nail a section of rod on each object, making sure the foot or meter mark at the bottom of the rod is exactly on the marks placed on the object.
Step 3
Compare the readings. Ignore the whole foot/meter parts of the reading as they may not be the same since a different part of the rod was glued to the object. However, the decimal part of the reading should be the same if the instrument is in proper adjustment. If the decimal parts are different, the instrument needs adjusted.
So, one person, one setup, two readings, and a simple comparison within a minute or two to peg a level.
