Iam new to OP, still learning. I have connected a fuel filter vacuum/pressure sensor via a ADS1115
The sensor operates at 0,5 to 4,5 Volts but I only see 4,006 Volts as maximum. Can this be adjusted with Gain ? and where do I access the Gain Adjustment ?
The sensor should be linear but is it possible to add Calibration points if not ? and where do I do it ?
Thanks in advance

Have you checked the output of the sensor with a multimeter to see what voltage range it is actually producing?
OP sets the gain for the ADS1115 by default to 1 giving you a measurable range of 0V to 4.096V. You can change the gain if required but I would start by verifying the output voltage with the meter.
