For low power applications, it is recommended to set the divider TMEAS_TRIG_PREDIV to

such a value that the temperature measurement is done maximum 10 times per second.

Be aware that the resistivity measurement is based on an AC, not a DC, method. So,

cable between sensor and chip may contribute shift and noise through its inductance and

capacitance. Twisted shielded cable may be a good choice, in some cases an active shield

may help.

Issue a start command (op code 0x8C) and begin polling data or watching INTN. See

sections 5.3, 6.5.3 and 6.5.4 for details. What you read is R0/Rref or R2/Rref, a ratio

between two resistivities.
