Specific Conductance Temperature Coefficient
In ODO/CT probes, the standard temperature reference coefficient used to calculate specific conductance can be modified by the
user. The value is set by writing an entire block of values (non-divisible) using a write multiple registers command (function code
0x10). This information can be broadcast to all devices on the network. The default value is 0.0191 and is saved over power cycles.
Valid values range from 0 to 0.04.
