The 1/1N asa knob is supposed to turn 360 degrees. If the knob is very
smooth spinning, you should feel some resistance going from 25 to 1600
(that's where the cam goes up-hill). Most 1s when set to asa 100 with the
meter off, will center the needle when you set it to B and f1.8. Sounds
like the asa plate may have been taken off / fallen off and put back in the
wrong place. If the plate is off, you'll see a small tab that engages a
notch in the knob. Turn the knob to the 3:00 position, then slightly
clockwise to the first locking position after 3:00. That is asa 100.

Subject: Re: [OM] OM-1n meter and ASA problems
Thanks everyone for helping me solve the puzzle. I have come to the
conclusion that it's the ASA dial that's broke. That's why I was
confused. Set at B, f1.8 and 100ASA with meter OFF, the meter hits
the cealing. It centers when I turn the ASA-knob to 25 *or* 1600.
Turning the meter ON and comparing readings with my CLA'd 4T, shows
that 200 ASA on the 4T equals 40 ASA on the OM-1n.
The ASA-knob is also possible to turn 360° (not good, eh?)
So, next Q: is this a major surgery thing, or something easy to fix?
Over or under the $50 limit? (There is an Oly-technician here and he
seems to charge standard prices.)
Again thanks, and an OMy 2002 to everyone
Henrik Dahl
