There is a potentiometer for meter adjustment. It is visible under the top cover and you have to remove the rewind knob and the film reminder parts underneath to expose the adjustment hole. However, two stops is quite a bit to adjust, most likely a problem other than calibration. I would check if the meter is non-linear - is the error the same at high and low light levels. If it is non-linear, I would suspect the photo cells. If the error is the same at all light levels, the calibration pot may work for you. Also, you did not mention the model of Spotmatic that you have. The Spot F is different and the very early Spotmatic does not have an adjustment access hole. |

Do you mean the SP1000? If so, the adjustment hole is visible under the rewind side film reminder cover. |
