ODO values can be reset to the factory calibration by issuing a write single register command (function code 0x06) at address
0x0200 with a value of 0x0001.

Last Calibration Time and QC Score
The time of the last conductivity calibration and QC score can be queried to help track internal processes for keeping the devices
properly calibrated. The last time must be maintained during calibrations by the user. These registers do not support writes, as time
is written in each calibration command. This is only intended to be read. Last calibration time is a 32-bit (two register) value, and
is recommended to be set as epoch time. The last calibration time and QC score are available as read-only using a read holding
registers command (function code 0x03) starting at address 0x0310.
