QHY9 Offset and Gain starting point

Hi guys - I'm trying to get around to setting up my QHY9 after a long time and had a few questions.

I followed the instructions from the following PDF CLICK HERE.

For the first test i.e. 0 Gain and 100 offset I get the following result:

Exposure(sec) - Mean Pixel Value
0.02 - 50714
0.04 - 50808
0.08 - 50835
0.16 - 50858
0.32 - 50865
0.64 - 50873
1.28 - 50859

Not sure what I'm doing wrong? I'm testing at night in a room which is dimly lit. Should I not be using the 100 offset as a starting point?

Any help would be appreciated.
