Hi all
I compute a simple formula: V*V/R with a Picoscope 3000. I'm using last Picoscope software on Windows 10.
It work fine setting 8 bit resolution, but with 12 bit resolution the result is completely wrong, about an order of magnitude.

Do you have a .psdata file.
It looks like black and blue are both math channels.

No. I will create a new one

Yes, both.
Black: B/27000 (27000 is a resistor value)
Blue: B*B/27000
Thanks

Yes, both.

Blue: B*B/27000

This problem born if you set 12 bit resolution AND X10 probe
No problems using 12 bit resolution and X1 probe
No problems using 8 bit resolution and X10 probe
Red and blue: measure
Black: math (B/27000)
Cyano: math (B*B/27000)
Lime: math (A*B/27000)
Thanks
