Fuel Tank visual display

[TundraJoe]

My EMS displays what looks like a circle --with an opening in the circle at 360 and 180. Below the circle is Gals and under each 1/2 circle appears to be CAL ? IS this a visual display of the estimate fuel in each tank? If so, how is it set , because I am not getting any visual display--the circle is always empty. and what is CAL ?
Thanks
Frank

CAL simply means that you haven't calibrated the fuel levels yet. Until you do, they can't give you any readings at all. After you calibrate, those semi-circular gauges visually "drain" with your tanks. Refer to the installation manual for a full description of the calibration process, with full instructions. They're available here
