Hello, <p> I am trying to get an instruction manual for my recent acquirement of MR4(I think) light meter. It has a push button on the top. A dial on the top that you can turn to either the black dot or red dot. On the front, toward the field, there is a lever that slides to the left, and when you let it go, it returns itself( I guess it has a spring tension action). It is operated by a battery. <p> I don't care if it's a photo-copy version. As long as it tells me how to use it. <p> Thank you for your help.
