3.1.2.1. Oblique 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
situation to exist.
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 (gimbal, compensator weight and shaft.,
screw adjustments) 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 0.0005"/in), only fine adjustments need to be made, i.e. calibration via the
remote control. Larger errors (>.5mm/m or 0.0005"/in) require coarse adjustment to get close, then fine adjustment to bring the
unit within specification. Both adjustments are defined below
Fine Adjust - Calibration via The Remote Control
If the error is within the range of ±0.5mm/m, it only needs to make calibration with the aid of remote control. The details are as
