My first Pico! 6403D.

Quick one... why they put the "tuned probe TA150" in the label, can't I just use the 10:1 probe I want? Sure I will compensate them....

While you could do it through calculation (I don't know any instrument that does) From the datasheet.... A 3-wire connection is a compromise approach that uses one less conductor than the 4-wire approach. To compensate for the voltage drop across the return wire, the voltage between FORCE+ and RTDI...

Don't beleive all you read on the web. There are lots of "experts" on all subjects spouting rubbish. Thanks Rob, you read my mind. I will try to contact Adafruit to correct it. That said in the 3 wire configuration they are somehow right, the ADC remove the imaginary drop on the negative ...
