The measuring
pr
ocess
5.1 Preparing Measurement
Connect the sensor plug of the aw sensor to the basic device. Now the switched on
device shows the current temperature and activity of water value.
Fill the plastic container with material at least two thirds full (~50-60g). In
case of coarse, lumpy material the container should be filled at least half-way
so that the moisture conditioning can be guaranteed. The higher the filling,
the faster the conditioning. A too low material quantity may cause a deviation of the
measuring result.
The material to measure must not come into contact with the metal protective
grid (the red line on the picture below is the absolute maximum level)
The material must not enter the inside of the grid!!
After the filling, close the measuring chamber tightly.
The right measuring value can be read off when the displayed value does not
change any more over a longer period.
(Experience value for adjustment time: Change of aw value from 0.4 to 0.6 within 10
minutes).
With unpeeled materials such as nuts it may take longer until the sample releases
moisture in its surroundings for the measurement (see AW3).
For a rapid conditioning (see AW3), the water activity measuring chamber is
equipped with a ventilator. If the humimeter AW1 basic device is switched off, the
conditioning time is extended. In case of using the automatic datalog with a
datalog time of more than 30 seconds, the device switches off
automatically between the measurements.
The filled and closed measuring chamber must not be turned over. Otherwise
the measuring sensor positioned in the cap may be polluted by the sample
material, which leads to wrong measuring results.
Do not fill above this line

5.2 Taking a measurement: Steps To “Real”aw
Step 1: Insert Sample into AW Cup
Step 2: Grind / Homogenize Sample
Step 3: Close AW Cup
Step 4: Turn on to Log Readings To
Stability; typically < 5 minutes

A
T
TENTION
Pollution
of
t
he
sensor
with material
If the
screw-top
jar
is
filledtoo high,the
sensor can become
polluted,which
leads
to
incorrect
measurements.
►
Make sure
that the
metal protective
grid
does
not
come
into
contact
with
the
material being
measured.
A
T
TENTION
Pollution
of or damage to
t
he
sensor
By
tilting or turning
over
the filledwater
activity measuring chamber,
the
sensor
can become
pollutedor
damaged,
which
leads
to
incorrect
measurements.
►
Make sure
to onlylift the water
activity mearuing chamber straight
up into
the air.
i Information -
Measuring
accuracy
This
rapidand
non-destructive measuring procedure allows
youto
take
multi-
ple
moisture readings
of the
same sample material. When saving
the individual
readings,
the
device
will
automatically calculate
the
readings’ average
(see
"6.2.2
Saving several readings (a measurement series)
at the
same
time").
i Information -
Incorrect
readings
Always make sure
to
select
the
correct
producttypefor the
material
youare
measuring. This prevents
taking
incorrect readings (see
"13.
F
aults"
).
