How do I calibrate the SSC200 roll to read zero using Maretron’s DSM150, DSM200, or DSM250 display?

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:

1. Enter menu mode, scroll to "Configuration..." and press
2. Scroll to "Device Configuration..." and press
3. Scroll to the SSC200 and press
4. Scroll to "Installation Offset Calibration..." and press
5. Even though it appears that you are aligning the compass, go ahead and press . Pressing  not only sets the alignment of the compass but it also zeros both the pitch and roll
