    Well of course.

    I agree with you, I tried the 1.3 wein cell and the needle is further up. Any suggestions?
    Thanks

    In all probability the meter would work fine but the glue used to bond the meter cell blocks to the prism has yellowed and cracked. The fact that your is indicating above this rectangle tells me not enough light is reaching the cells. If the battery voltage is above the 1.35v needed the needle will drop below this rectangle..
    for more information..

    You can recalibrate the BC function. If you remove the base plate there are 2 variable resistors (potentiometers). One of them is for the light meter and another is for the battery meter. But I personally wouldn't worry much about the STt 101 meter, I would rather use it as a meterless camera.

    Argh. I had it backwards. Sorry - it's been at least 4 or 5 years since I handled an SRT.
