You can calibrate the SSC200 roll to read zero when the vessel is sitting flat in the water using a DSM150, DSM200, or DSM250 display. To zero the roll:
- Enter menu mode, scroll to "Configuration..." and press < Enter >
- Scroll to "Device Configuration..." and press < Enter >
- Scroll to the SSC200 and press < Enter >
- Scroll to "Installation Offset Calibration..." and press < Enter >
- Even though it appears that you are aligning the compass, go ahead and press < Enter > . Pressing < Enter > not only sets the alignment of the compass but it also zeros both the pitch and roll
