Soligor SENSOR CDS light meter question...

[mindcircus]

Hello, did anybody ever had this light meter? I don't have it's user manual and I am trying to find out why its sensor is collapsible. It gives me different values when it is totally collapsed, when it is half collapsed or when it is not. The previous owner told me that you increase its optical view while you collapse it, but it doesn't make much sense since it should give the same values in a uniform surface...

Thanks in advance!

For High and Low Light?

In many meters, the sensor moves in or out, to allow light to shine on it more or less respectively.

Usually, sensor is pulled out close to the window to let more light to fall on it in low light shooting situations.

In bright light, the sensor is pulled in so it doesnt get blinded by too much ligh.

Thanks for your answer but I don't think this is the reason. It has an option for measuring in low or normal light. I attach some pictures that may help
