First, I think you must be referring to the FT-QL. I've never heard of the model you named. The QL just means quick loading. It means that the camera has a part that holds the film leader down when loading the camera, so you don't need to insert the leader into the takeup spool when loading the camera.
There are three things you can do to get the two needles to line up: 1) change film speed, 2) change shutter speed, 3) change f stop.
Oh yeah...and 4) change battery! The camera's proper battery is no longer made. If you want to use the light meter, I'd suggest adapting a 1.4V #675 hearing aid battery. They are dirt cheap and require no electronic changes to the camera. You have to use some sort of washer to get them to stay put in the battery compartment, as they are smaller than the original batteries. They have to be replaced a few times a year, but the good news is that they are cheap as dirt.
But I'd honestly suggest just using a hand held meter instead, due to the imperfections inherent in all in-camera light meters.
This camera requires stopping down to meter. It is basically a sister camera to the Pellix, with a normal mirror instead of a pellicle one. When FD came along, the FD equivalent of it was the FTb, though there are slight differences aside from the automatic aperture and full aperture metering of the FTb.
