<p>Okay, late to the party, but I hope this helps<br>
Set the ISO of your film on the camera; let's assume it's ISO100 - take it outside on a bright sunny day- set shutter speed to 1/125- leave lens on A - it should state a F stop of 16 or so - if yes- meter is working<br>
Raise the shutter speed, and your lens will open up (lower F number)<br>
Lower the shutter speed, and your lens will stop down until it hits it's minimum </p>
