LR510
Horizontal use of LR510
• Set up the LR510 on a surface that is as level as possible or fasten it to a tripod.
• Turn the pendulum lock in the arrow’s “Unlock” direction to its limit. This releases the
locking mechanism that protects the pendulum during transport.
• Press the On/Off button.
• Within its range of +/- 3,5°, the LR510 will level itself automatically and the prism head will
begin to turn.
• The speed of rotation can be changed using the up & down buttons from 100 - 300 RPM.
Vertical use of LR510
• Turn the pendulum lock in the arrow’s “Lock” direction to its limit.
• Insert the vertical operatin foot into the vertical foot recepticle and adjust the foot untill the
vertical operation vial is centered between the centre markings.
• Press the On/Off button. The prism head will begin to rotate.
Note:
Always unlock the pendulum lock when the LR510 is being used for horizontal
levelling by turning the transport lock to its “Unlock” position. If the unit is currently
outside of its automatic levelling range (> 3,5°) , a warning signal will sound and the
prism head will not rotate. The unit must then be placed on a surface which is closer to
level. When in vertical use, the unit does
not
level itself automatically.
