Metering in manual mode on nikon n65?

I'm trying to use the camera's meter on my nikon n65 in manual mode but the meter doesn't change it is always indicating that it is underexposed no matter how much i change it. The meter looks like this +2 +1 0 -1 -2. Can anyone help explain how I can get the meter reading to zero?

Added (1). Taylor-That is what metering does, it tells you the exposure composition (shutter speed, aperture setting) for finding zone V or middle grey. That's what the zero will tell me, how to find zone V.

The +2 +1 0 -1 -2 indicates exposure compensation, not metering.

No idea what you mean by exposure composition.

If it's buried at the underexposed end of the scale, you either have to drop the shutter speed to a much slower setting, open up the aperture or use a faster film.

And it won't tell you how to find Zone V, it will render whatever you're metering on as Zone V.

The F65 (or N65 as it is known in the US) is a 35mm film SLR camera introduced by Nikon in 2001.[1][2] Like its predecessor, the F60, it was aimed at the lower end of the amateur autofocus SLR market.
Its facilities included autofocus, various forms of TTL light metering and different operating modes. It also included depth-of-field preview and remote shutter release, two facilities notably absent in the F60.
The F65D variant featured a date/time-imprinting facility.
In 2002, the F65 was joined by the F55, which was targeted at a new, lower price point.[3][4]

Can you provide more details such as the lens and the film you are using? When is the last time the camera had a CLA (Cleaning/ Lubrication/ timing Adjustment)?

The first thing that comes to mind is that you are not using a DX coded film (a DX coded film canister will have large silver blocks on the side). If you use a non-DX canister, the camera will default to ISO100.It could also be that the camera is not reading a DX canister properly.

The other thing I can think of is stuck aperture blades on f/16 or f/22.
