ALIBRATION
Although calibration of the OceanServer OS5000 Series Digital Compass is
performed at the Klein Marine Systems, Inc. factory, it may be desirable to
calibrate the compass to account for the differing magnetic fields in other parts of
the world. Calibration can improve the accuracy of the compass readings.
C.1 Required Items
The following items, which are shown in Figure C-1, are required to perform the
compass calibration:
• Compass assembly (P/N 14105534), removed from the frame. To
remove and install the compass, refer to “Removing and Installing
the Optional Compass” on page 4-13.
• Laptop PC with and available RS-232 serial port and OS5000
Windows Compass Demo Program V2.6 installed, available as a
download from www.ocean-server.com.
• Cable harness with 5-pin bulkhead and DB9 connectors and a
3.6 V battery pack.
• Nonmetallic rotatable table or cart.
