4.1.2.1 Qblique/Inclination error

This type of error occurs when leveling compensator does not hang straight (as

illustrated to the right), i.e. is not properly balanced. When the laser spins, it

actually rotates on a plain that is not level, i.e. perfectly horizontal whose rotating

axis is not plumb. So value A on the left target does not has the same sign as that

on the right target, like, A



Normal use – Depending upon how careful the user is with the instrument, finely tuned adjustments can be

altered by very large changes in temperature, vibrations (due to handling and transportation)



Shock – The instrument was dropped and components of the leveling system have either been damaged or

came out of alignment. If defective components are present, they will need to be repaired or replaced

prior to the calibration procedures defined below being initiated.

Depending upon the magnitude of the error (±5mm or 0.2"), only fine adjustments need to be made. Larger

errors (>5mm or 0.2") require coarse adjustment to get close, the fine adjustment to bring the unit within

specification.

Note: Only fine adjustments are discussed in this document. Coarse adjustments are integral to the core

module and are factory adjusted. Units that have defective core modules, or core modules that need

coarse calibration should be replaced by the service technician and the defective part sent back to the

factory for repair/recalibration.

Access calibration mode by simultaneously pressing the "Power" key and the

"Tilt" key.

While continuing to hold the "Tilt" key, release the "Power" key.



When releasing the "Power" key, all red LED's on the unit's keypad

display with light up. After about 10 seconds, all LED's, except the

power LED will go off.

Release the "Tilt" key.



Note that the rotating head of the laser is not rotating but the laser is flashing. The unit is now in

calibration mode and all other operations will be performed with the unit's remote control.
