All OM-1 meters will move when set to OFF or without batteries. Just set to
B, and start opening the lens to the widest aperture.

Subject: [OM] OM-1n meter and ASA problems
> My OM-1n has developed a strange behaviour.

> - The meter activates on both "on" and "off" position. With lens on
> open (5.6~2.8) and in the shutter range
> 1s~1/60 it acts as if metering the light, but does not *react* to
> light. It rather sets itself to different fixed positions. In other
> words it doesn't matter whether I point straight into a light source
> or to a dark corner.
> - The strange thing is that it does this even with the battery taken
> out! So it must be some kind of mechanical fault.
> - With battery: in daylight, with lens stopped down and in higher
> shutterspeeds, it starts to react as normal to light changes.
> - It may have to do something with the aperature lever on the body.
> With lens off I can manually turn that and provoke the erratic meter
> behaviour.
> - The ASA dial is possible to turn infinitely.
> - It doesn't matter what lens I try, so the problem lies not there.

> Every OM-1 body will display this behaviour. Remove battery, set ASA to
