Unit NTU (optionally FNU)
NTU (Nephelometric Turbidity Unit) is a unit of measurement for measuring the
turbidity of liquids. Alternatively, the measurement can be expressed as FNU
(Formazine Nephelometric Unit), see
Ä
„Units“ on page 48. The calculation is
undertaken 1:1.
Measured values over 1000 NTU are outside of the sensor's measurement
range. Measured values over 1100 NTU cause the display to flash and a mes‐
sage to be displayed warning of excessive measured values.
During normal operation of the sensor, an arrow is positioned next to
[AUTO] .
In this state, the lower row indicates the unit of measurement and the upper row
shows the current measured value.
