4) TDS is proportional to the value of conductivity. The TDS coefficient ranges from 0.40 to
1.00. Users can adjust TDS coefficient by experimental data or experience in P4. The
following chart lists some commonly used TDS coefficients for reference (Factory default
value is 0.71).

5) Salinity is proportional to the value of conductivity. Its coefficient is 0.5. Users only need
to calibrate conductity, and then switch to TDS and/or salinity to take measurements.
6) The tester has self-diagnosis functions:
