The device can report the turbidity of the process water in Nephelometric Turbidity Units (NTU)
or Formazin Nephelometric Units (FNU). Readings above 10 NTU/FNU, 100 NTU/FNU or
1000 NTU/FNU (depending on the specific device measuring range) are outside the range of this
device.
During normal operation, the display shows an arrow beside "AUTO" in the upper left corner.
Simultaneously the lower row displays the current scale and the upper row the measured
reading. The following drawing is an example for a display during normal operation:
