Setting Selection/values Explanation
Measuring mode  Concentration
 Saturation Unit of the measured value on the measured
value display.
Measuring range
Concentration  0 ... 20.00 mg/l
 0 ... 20.00 ppm These measuring ranges are available for
selection.
Measuring range Sat-
uration  0 ... 200.0 % The measuring range is set permanently.
Response time t90  150 .. 300 s
(with SC-FDO
®
700)
or
 60 ... 300 s
(with SC-FDO
®
701)
Response time of the signal filter.
Depending on the sample matrix, the mea-
sured values may fluctuate more or less.
A signal filter in the sensor reduces the fluc-
tuation range of the measured value. The
signal filter is characterized by the Response
time t90. This is the time after
which 90 % of a signal change is displayed.
The setting range depends on the sensor
cap type.
Calibration
 Factory calibra-
tion

User calibration
 active
 abort
Determines which calibration data the mea-
sured value calculation will be based on. The
active calibration is displayed in the calibra-
tion history.
The selection, User calibration is only dis-
played if valid data of a User calibration is
stored in the sensor.
active indicates that the sensor is being cali-
brated.
If abort is selected, the active calibration is
canceled the next time the setting table is
quit with Save and quit.
Test  active
 abort active indicates that the sensor is being
checked.
If abort is selected, the active check is can-
celed the next time the setting table is quit
with Save and quit.
Temperature mode  °C
 °F Unit of the measured temperature value
(Celsius, Fahrenheit).
