• Not possible with Wave-and-Read function. Attempting such
measurement with the Wave-and-Read function will result in an
error.
Important:
Formula for correcting expansion and contraction of the
staff due to temperature changes
C={C0+(T-T0)x }x h
C: Staff correction value
C0: Scale factor
T: Measured temperature during observation (average
temperature during measurement of known site,
intermediate site, new site)
T
0: Reference temperature of 20 C
: Line expansion coefficient
(BGS series : 20x10
-6
1/ C)
h: Height difference
