Using , switch from the measured value display to the main menu
of the settings. Then navigate to the setting menu (setting table) of the
sensor. The exact procedure is given in the relevant IQ

system operating manual.
Temp. adjustment
-1.5 K ... +1.5 K
The temperature compensation enables the
temperature display to be balanced (shifting
of the zero point by ±1.5K).
Notes:
Due to the thermal capacity of the sensor,
it is necessary to place it in a container
with at least 2 liters of water.
Leave the sensor in this container for at
least 15 minutes while stirring occasion-
ally until the balancing can be performed.
With temperature differences between the
water and sensor > 10 °C, leave the sen-
sor for at least 1 hour in this container
while stirring occasionally until the balanc-
ing can be performed.
Salinity
On
Off
Determines whether the entered salinity
should be taken into account.
Salinity input
2.0 ... 70.0
The entry of the salinity enables a salt con-
tent correction that compensates for the
effect of salt contents > 0.1 % on the oxygen
measurement.
The salt content correction is recommended
for measurements in salt-contaminated
wastewater (salinity
≥ 2.0 corresponding to a
conductivity of
≥ 3.4 mS/cm at a reference
temperature
TREF
= 20 °C).
Sensor cap data
Do not download
Transmit to log
book
Generates a log book message with all data
stored in the sensor cap when the settings
are quit with Save and quit (see section
1.2).
When opening the menu again the setting is
reset to Do not download.
Save and quit
The system confirms the saving of the set-
tings and the display switches to the next
higher level.
Quit
The display switches to the next higher level
without saving the new settings.
