Since you're seeing "12.something volts" and no amps and 0 salinity, it indicates that your RJ+ which ships configured for 220/240 volts, is receiving 110/120.
If you indeed have it wired to 110/120, you'll need to refer to page 18 of your manual where it will explain how to make the simple internal adjustment to reconfigure the unit for 110/120.
