Hello Dieter,


I have an issue with the A156.

Besides the small notes on your website about tuning the A156 is there a more specific thing to measure
Between the steps of 0.0833333 V there is a small window of quantizing.
When the voltage goes up and down there it switches differently.
I ask this because I used the P4 with a reference voltage of 1.00 , 2.00 , 3.00 and 4,00V.
Afterwards I used P1 and P2 to adjust but then I lost it a bit.
Within voltage steps everything seems ok but now I"ll have to put the 0,083333 steps one by one and see if the output follows right
Where are the points where the quantizer switches
What is the factorysetting for that, when going voltage up and when down.

Hope that I made a clear explaination.

Best regards.
