Frequently Asked Questions
On the current N-LF2000 models, this means that the conductivity value is above the upper limit of the measurement range. To be more precise: for conductivity values above 2050 µS/cm, the display shows “EEEE µS/cm”, which means that the measurement range has been exceeded.
