Assuming you are shooting to 1400 yards, then the sight works as follows.
Using the lower aperture sight, there should be a faint line/arrow pointing towards the right side sight graduations. If you align this with the numbers on the right, that will have the rifle ok for elevation (assuming you are using the service cartridge) out to 1400 or so.
If you are using the v notch sight, then similarly, align the line on the right side of the v with the elevation and you will again be on out to around 1400.
If you lower the sight so the v notch is at around 175 yards, then you will be about 6" high at 100 yards if you use the aperture sight.
The battle sight is zeroed for 260 yards.
Windage is about 5 MOA per division
All of this is with the 45-70-500 cartridge for the rifle.
Spencer Wolfs book Loading cartridges for the original .45-70 Springfield rifle and carbine explains this sight a lot better than I can.
