Calibrating fuel tank display on 4500
Rob, I'm a little ways from starting the engine, so the fuel tanks are empty. But the fuel tank display on the 4500 EFIS indicates the tanks to be full. I want to fix this so it indicates exactly what fuel is in the tanks (none). I've looked in the installation/user manual, but can't see where it addresses calibrating the 4500 and when I follow the steps outlined I get no where. Tell me I'm overlooking something simple and what that something is.
Thanks,

Calibrating fuel tank display on 4500
I am having trouble calibrating my fuel tanks. Aircraft is a Sportsman 2+2 with IO 390 engine
I get to the calibration page ok and see Instrument Calibration 1. Tank size through 6. Units.
I don't see 7. Num Cal Points of any AD Value displayed. How do I get these displayed so I can do the calibration. It is almost as if
some admin has these locked so they can't be changed. I have a few gals remaining will the calibration numbers show up anyway
without zero fuel. Or maybe it's the fuel probes. I've looked in the Admin settings and don't see anything.
Hopefully Rob will reply to this thread or someone who's been there. HELP
I found the answer which was simple: I was trying to calibration from the left side the FLIGHT EMS need to do it form the right side the Engine EMS.
Hope this helps others.
