I have an OM1n with a meter that is reading about 1 1/2 f stops low. The battery voltage is correct (via CRIS adapter), so I need to adjust the meter. Is the cam on the meter housing the best way to do this, or could I shift the position of the timing gear that communicates the aperture information to the meter movement? |

The cam on the meter housing is intended for this purpose, and if your error is linear this is where I would adjust it. There is no electrical adjustment in the OM1, so if a cell or resistor has gone bad all you can do is replace it. |

Thanks, Rick. While I was checking my Olympus SLRs against a known accurate OM4, I found that my OM2 meter was off too. How hard is it to tweak the meter in the OM2? |

the VF meter adjusts similarly to the OM1; of course this doesn't affect the autoexposure system. |

Not sure about the OM 2, but on my OM 20 (G) there are 2 variable resistors that adjust meter reading for low and for high light. I found a good manual on http://olympus.dementia.org/hardware/ with everything well described and with images. |
