DESCRIPTION
The pt1000_calib utility is used to determine and save the voltage offset for each Pt1000 sensor.
The utility operates by measuring the temperature using a Sensirion SHT sensor, measuring the voltage output of the Pt1000 sensor, and back-calculating the voltage offset.
For the utility to operate, the I2C address of the Pt1000 ADC must be set. This is done using the interface_conf utility.
Note that the scs_dev/gases_sampler process must be restarted for changes to take effect.
