Tripod legs should be equally spaced

Tripod head should be approximately level

Head should be directly over survey point

Step 2: Mount Instrument on Tripod

  on Tripod

• Secure with 
  centering screw 
  while bracing the 
  instrument with 
  the other hand

• Insert battery in 
  instrument before 
  leveling

Step 3: Focus on Survey Point

Focus the optical plummet on the survey point

Step 4: Leveling the Instrument

•  Adjust the leveling foot screws to center the

survey point in the optical plummet reticle

• Center the bubble in the circular level by

adjusting the tripod legs

• Loosen the horizontal clamp and turn instrument until plate level is parallel to 2 of the leveling foot screws

•  Center the bubble using the leveling screws- the bubble moves toward the screw that is turned clockwise

• Rotate the instrument 90 degrees and level using the3rd leveling screw

• Observe the survey point in the optical plummet and center the point by loosening the centering screw and sliding the entire instrument

•  After re-tightening the centering screw check to make sure the plate level bubble is level in several directions
