Hi Louise,

it's good once you know - as always it pays to read the book ! -

however I happen to know that too many cameras left the QHY factory with this problem.

I shouldn't have had to adjust anything.

cheers

I agree, though maybe changes in temperature and humidity affected the factory settings. Of course, that would point to bad design!

Thanks Louise - but at least it's now solved.

I forgot to mention the findings from the previous page:

The info provided by QHY is misleading.
They say 2.2 Volts but their Oscilloscope documents show 2 + .2 of a division
( because they are on 2 Volts per centimeter ) which is actually 2.4 Volts.
When I checked my QHY9 it was 2.4 Volts but the waveform does not look
identical to their picture.

 

Maybe the factory actually got mixed up when they adjusted the camera?

cheers

Maybe lost in translation...
