It was a custom


Thank you for replying back to me.

Will this custom unit calibrate to atmospheric pressure and form a line scaled to zero on your scope?


On the Pico when it's unfiltered it looks like its on 0. Zoomed in and filtered though it's about 1.5 above 0

That sounds like a very noisy pattern.

You will not be able to accurately measure any pressures if you don't know were zero is. Wink

Thanks. Can't compare the accuracy of yours. I would love to get the WPS but for what I do for family and friends and doing it for free, for it's price doesn't justify it. BTW I'm from New York.
