Potentiostatic measurements require a 1-point calibration:
Since the measurement depends upon the flow-rate and calibration solutions would
not be stable anyway, the sensor cannot be taken out of the armature for calibration, as
is done with pH sensors. Instead the actual concentration of the test water is
determined by an alternative method, for example photometrically with DPD, and this
value is entered as calibration value. Calibration of the Oxygen measurement is
simpler, using the Oxygen concentration of the ambient air.
The measurement is influenced by temperature. This influence can be compensated
manually or automatically. For manual compensation the temperature is entered
manually, for automatic compensation temperature has to be measured with a
temperature sensor. For the temperature compensation a linear coefficient can be
adjusted as %/K.
For smoother measured values activate the averaging function.
If you have purchased an instrument with Automatic Sensor Cleaning ASR, the basic
settings will include „cleaning“ where you can activate the automatic cleaning, define
the interval between subsequent cleaning cycles and the time for the first cleaning
cycle.
NOTE
The menu „cleaning“ appears automatically when a sensor with ASR
is connected.
