: Adjustments and Corrections
The instrument is under strict test and calibration, the quality is in accordance
with the standard demands. But after a long-distance of transportation and
environmental changes, the small change of instrument parameters is inevitable.
Therefore, the new purchased instruments should be checked and calibrated before
surveying to ensure the precision.
11.1.
Tubular Level
Check
See reference in using tubular level to level the instrument precisely.
Calibration
1.
In the calibration, if the level bubble diverges from the center, use the foot spiral
which parallels the leveling tube to adjust to make the bubble move half of the
distance to the center. For the remaining, use the calibration needle to turn the
level calibration screw (in the right of the water-level) to adjust the bubble to the
center.
2.
Turn the instrument 180° to check whether the bubble is in the center. If the
bubble is not centered, repeat step 1 until the bubble is in center.
3.
Turn the instrument 90°and use the third foot screw to adjust the bubble to the
center.
4.
Repeat the steps of checkout and calibration until the bubble is in the center in
every direction.
