Installing the 3TB in a borehole
You should see an
ok
prompt, indicating that the digitizer is ready to receive
commands:
2. Type
0
rotation
AZIMUTH
where
rotation
is the angle of deviation from true North that you measured
earlier, as a whole number of tenths of a degree. This is the same angle (with
the same sign) as that given by the orientation program.
The
0
tells the digitizer to apply the rotation to instrument number 0 (the first,
or only instrument.)
Thus in the example above, you would type
0 -903 AZIMUTH
to make the
digitizer rotate signals by –90.3 degrees.
