c. Final X,Y Note
: If the platform is not level during the calibration procedure
just abort (by hitting the SPACE bar) and re-run it. (i.e. Hit space and start at
step a above).
Step 4 (Z Calibration)
: Rotate device (90 degrees) so it is turned on its side
a.
Roll the platform 90 degrees,
The area should be clear of soft and hard iron
objects that could disrupt the earths magnetic field, cars, motors, wires with
current, magnets, etc. You want the calibration to be done in the same place as
the “C” calibration as it needs to see the same earth’s magnetic field
b.
Enter Z Calibration mode
. Push <esc>Z on the keyboard. Slowly rotate the
device 360 degrees (at least one complete rotation). This step should take 20
plus seconds when you just get “…” you have found the “Z” max and “Z”
min values. Terminate the sequence by hitting the SPACE bar. Important
Note: The “Z” command should be done in the same location to calibrate and
align the Z axis sensor to the X, Y. This is important for tilt compensation.
Errors in heading, when the device is tilted, will result from no Z axis
calibration
Note:
If the platform is not level during the calibration procedure just abort it and
re-run it. (i.e. Hit space and start at step 3 above). Compasses can also be
calibrated in the latest version of the OceanServer Windows Demo program. The
basic steps are the same as described above. The feature can be found under the
“program” button.
