26. CHECKS AND ADJUSTMENTS
A SET is a precision instrument that requires fine adjustments. It must be
inspected and adjusted before use so that it always performs accurate
measurements.
• Always perform checking and adjustment in the proper sequence beginning
from "26.1 Plate Level" to "26.8 Guide Light".
• In addition, the instrument should be inspected with special care after it has
been stored a long time, transported, or when it may have been damaged by a
strong shock.
The bubble tube is made of glass, so it is sensitive to temperature changes or to
shock. Check and adjust it as outlined below.
