    It is different for each lens, so you need to choose your lens first. Then, look at the lowest f number on the aperture ring, e.g. f/1.4. Whatever that is, you line up the EI with it on the meter. You need to lift the ring to rotate it.

    Use the box speed of the film [ISO, ASA ...] as the EI. EI is the Effective Index which for now use the ISO. You can learn about EI later if you want to use a variant of the Zone System [ZS]

    Look for a manual at http://www.butkus.org/chinon/nikon.htm If you find what you need please remember to send him the $3.

    EI is the number that you put into your exposure calculations or light meter. In other words, it is how you "rate" your film.

    Box speed is box speed because it works for an average shooting in average conditions. It should get you a usable image, though usually not "ideal," most of the time, so I'd start with that for your EI.

    Lets another whack =)
    ASA/ISO is the film manufacturers rated speed for a given film. IE: Tri-X=400.

    EI is Exposure Index, a film speed rating different than the manufacturers.
    Usually found by testing your exposure/development techniques to find an exposure that gives the results you want. Usually a full range of detail, but not necesarily, you may want higher or lower contrast or a more or less dense negative.
    The NikonTn meter has a series of maximum apertures on top of the SS dial. To set the ASA/ISO. You set the max aperture of your lens to the appropriate mark on the dial.
    This needs to be changed when you change to a lens with a different maximum aperture.
    Because this is the manufacturers rating, it not EI but is ASA/ISO.
