ASA 3200 for 1 second is way outside the range of sensitivity of the FM light meter. 30 plus years ago, my new FM's light meter could not handle 400 ASA at 1 sec and f1.8.

If you want to test the meter, set it to ASA 125 and then check for the sunny 16 rule (in sunlight, should be about f16 and 1/ASA, or 125 in this case).
