Conductivity Temperature Compensation Selection
The temperature compensation can be turned off or set to Linear, nLFn (non-linear ultra pure non-degassed
water), nLFu (non-linear ultra pure degassed water) or EP (temperature compensation off and warning is
displayed if conductivity values are outside EP requirements for ultra pure water) and is used to report all
conductivity measurements at the selected reference temperature.
