While Manual-leveling, Self-leveling, and Automatic-leveling (motor driven) devices have different mechanisms that require calibration, there are similarities with optics that is consistent regardless of the leveling mechanism. This section of the service manual discusses calibrations specific to the 40-6537. Each item discussed is shown below. -
Page 7: Quantifying Accuracy Error
40-6537 Service Manual 3.1. Horizontal Mode Operation In this mode of operation, the instrument is self-leveling, where by a major factor of accuracy is how well the leveling compensator is balanced. Different types of errors require different methods of calibration. These errors are easily characterized by placing the instrument on a flat surface following the guidelines below, and running the instrument with the rotating head continuously rotating 360°. - Page 8 40-6537 Service Manual 3.1.2. Characterize the type of error Use the following rules to determine what to of accuracy error the instrument for test has, and reference the stated section to adjust for it. Note that the unit my have a combination of different types of errors to adjust for, in which case, multiple calibration must be performed.

Page 9: Oblique Error
40-6537 Service Manual 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. - Page 10 2. X-axis calibration SLO PE Press the key one time and verify that the X-direction LED on the keypad of the 40-6537 flashes, indicating that it has entered the self-calibration mode on the X-direction. Press the key to adjust the laser beam up or down to coincide with the reference line.

Page 12: Taper Error
40-6537 Service Manual 3.1.2.2 Taper Error Taper error results when the prism base module (discussed in section 2.4, item 6.4.4) does not reflect the laser light exactly 90° (i.e. non-perpendicularity between the rotating line Taper error and the rotating axis). The end result is a laser rotating surface that is not a plane, but a tapered one as shown in the figure to the right. -
Page 13: Wave Error
40-6537 Service Manual 3.1.2.3 Wave Error This error occurs when the rotating laser surface is not a plane, but a turn up one as shown in the figure to the right. The rotating beam projected on the wall is crooked, Wave error similar to waviness, which is caused by the unbalance of rotating head. -
Page 14: Vertical Mode Operation
In this mode of operation, the rotating laser surface is a plumb plane, while the laser line projected from the top is in projecting horizontal. While in this mode, the instrument is manually level, meaning that accuracy is a function of how accurately the vial is calibrated. The 40-6537 is not designed for Vertical Mode Operation. 3.3. Alarm Calibration The alarm function is made up of 3 components, the 2 alarm PCB’s (7-15-17, 7-14-13) and the buzzer (10-3). -
