Correction: KEH did not sell me a camera with a faulty meter. As it turns out, I learned about Nikon's "M90" feature the hard way. The camera actually had no battery at all! Originally, I had been stumped because the Nikkormat EL-W is a fully electronic camera (shutter and meter), and yet I was able to fire the shutter but the meter did not work. I did some reading, and found out about its M90 feature, a mechanical speed of 1/90th in case of battery failure. Thus, I had been shooting on 1/90th (i.e. without a battery). I inserted a battery, and the meter is fine (and quite accurate, too, considering the camera's vintage). I am sure my KEH salesman will have a good laugh over this one.
