The Signal Average mode measures 12 times and starts to
show the average after three readings. The final result is the
average of all 12 readings.

The Rapidly Settling Turbidity (RST) mode calculates and

continuously updates the turbidity reading of the sample to a

confidence of 95%, based on the accumulated trend of the

real time measured values.
The RST mode is best used on samples that settle rapidly
and continuously change in value. The reading is based on a
correctly prepared sample that is homogeneous at the
beginning of the reading. It is best applied to samples that
are greater than 20 NTU. The sample must be mixed
thoroughly by inversion immediately before inserting it into
the meter.
The target icon is shown on the display when the Rapidly

The Rapidly Settling Turbidity reads and calculates five
readings while showing intermediate results.
