Adjusting the circular level step-by-step
- Suspend a plumb line.
- Use a pole bipod, to align the prism pole parallel to the plumb line.
- Check the position of the circular level on the prism pole.
- a. If the circular level is centred, no adjustment is necessary.
b. If the circular level is not centred, use an allen key to centre it with the adjustment screws.
➜ After the adjustments, all adjusting screws must have the same tightening tension and no adjusting screw should be loose.
