6. Calibration Procedure (Latitude & Speed Error)

• Latitude setting: Rotate the latitude knob on the front panel to match ship’s latitude. Internally, this moves a mechanical weight inside the sphere.
• Speed error correction: If the compass is interfaced with a log, check that voltage from the speed input (0-10V = 0-50 knots) is correct at terminals S1-S2.
• Verification: After calibration, compare with GPS heading over 24 hours in steady turns. Residual error must be < 0.5° at 30 knots.
