Specific Conductance µs/cm Calibration
Specific conductance µs/cm calibration is accomplished by writing an entire block of values (non-divisible) using a write multiple
registers command (function code 0x10). Last calibration time can subsequently be read to verify. It utilizes temperature readings
of the probe, so they are not needed to be supplied by the user.

nLF Calibration
Non-linear function conductivity calibration is accomplished by writing an entire block of values (non-divisible) using a write multiple
registers command (function code 0x10). Last calibration time can subsequently be read to verify.
