The temperature coefficient is very dependent on the solution being measured and its
concentration level. The effect of temperature change on conductivity can be very
significant, and if the temperature coefficient is not know it is wise to measure all
samples at the reference temperature.

The TDS mode displays results that have been calculated from the conductivity
measurement and assumes some knowledge of the electrolyte balance of the
sample. The EC ratio allows selection of a factor suitable for the solution under test.
Most instruments that do not offer this option use a default value of 0.6.
