Check and Adjust the Instrument Circular Level
1. Set up the tripod and instrument stable.
2. Power on the instrument. Precisely level the
instrument following the electronic level.
3. The circular level should stop right at the
center.
4. If not, use the adjusting pins to adjust

Check and Adjust the Instrument Plate Level
1. Set up the tripod and instrument stable.
2. Power on the instrument. Precisely level the
instrument following the electronic level.
3. Turn the instrument and make the plate
level be parallel to a line linking two leveling
foot screws. The plate level should stop right
at the center.

screws till the bubble is in the center.
Check the Laser Plummet
The laser plummet spot should be checked on a bright, flat horizontal surface (e.g., on a piece of white
paper). The size of the laser spot is related to the condition of the projected surface and the ambient
brightness.
1. Set up the tripod and instrument stable.
2. Power on the instrument and level it precisely.
3. In “R60 Manager -> “Settings” adjust the brightness level of the laser plummet to project a clear
spot on the ground. Mark the center of the spot.
4. Slowly rotate the instrument horizontally one turn, observe the displacement of the centre of the
laser spot.
5. If the displacement is in a clear circular motion and the diameter of the track circle exceeds 3
mm, a calibration is required.
The laser plummet calibration needs to be carried out by an authorised service centre.
