hey guys,
I'm putting together a project in arduino to object the vacuum of a chamber using the 531 Thermocouple Gauge Tube, I'm using a 5V charger, so I have a range from 0V to 5V, where 0V is equal to 0 mTorr and 5V is equal to 2000mTorr (2Torr), The rendering is not getting adequate because it seems to me that there is a need to configure some formula of "Calibration curve", does anyone know what is the correct formula? with the return in Volts how do I correctly convert to Microns/mTorr?
