Putney,
My setup is different from yours as I have my GeoSatPro 1.2 M dish affixed to a motor (DG-380). However, you might find some information here that is useful.
For an inverted mount of this dish, you are to subtract 4.5° from the intended dish elevation to determine what the dish elevation scale should read.
Where I live near Omaha, NE - with my coordinates of 41.6°N / 96.4°W - the dish elevation required (when mounted on the DG-380 motor) is supposed to be 28.56°.
If I subtract 4.5° from 28.56° I obtain 24.06°. This is precisely where my dish elevation is set according to its factory scale.
Since you are setting this dish on a pole and not on a motor (I presume), things are going to change. The dish elevation required is going to be much lower and I don't
recall if the scale on the GeoSatPro goes that low. If I recall, it only is printed down to 10°. However, if it does, your required elevation is 14.37°, subtracting 4.5° results
in 9.87° - which would be what you should see on the factory dish scale if it can be read.
Now, I took some measurements off my system with the motor. Reading 24° on the dish's inverted elevation scale, I also read 34° on the LNBF arm and 76° across the vertical face of the dish using my inclinometer. These values themselves have no meaning to you for your setup. However, you might be able to use the relationship between them to aid you in some way.
I think if you subtract 4.5° from your desired dish elevation (14.37° - 4.5° = 9.87°) and add 10° to this, your inclinometer should read this (19.87°) when placed on the LNBF arm. Add 42° to this and that is what the inclinometer would read across the vertical face of the dish (61.87°).
