Carrying out settings Using
s
, 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 S
ENSOR N ET
system operating manual.
Salinity input 2.0 ... 70.0 The entry of the salinity enables a salt
content 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).
Temp. adjustment -1.5 K ... +1.5 K The temperature compensation enables the
tolerances of the temperature sensor 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
occasionally until the balancing can be
performed.
For temperature differences between the
water and sensor > 10 °C, leave the
sensor for at least 1 hour in this container
while stirring occasionally until the
balancing can be performed.
Save and quit The system confirms the saving of the
settings and the display switches to the next
higher level.
Quit The display switches to the next higher level
without saving the new settings.
