The sensor saves the current values of the selected parameters at
this point.
4. Take a water sample immediately from the closest point
possible to the sensor. Filter the sample as quickly as possible
and carry out a prompt laboratory analysis of the selected
parameters, as the measurement value can change quickly.
When the laboratory value has been determined, proceed as
follows:
5. Select SENSOR MENU > AN-ISE SC or AISE SC or NISE SC
> CALIBRATION > Enter the lab value.
6. The laboratory values for the parameters can only be entered if
the 1-point matrix correction correction has been selected
beforehand. Once the laboratory values have been entered,
select Confirm the entry. to confirm.
When the entered laboratory value is confirmed, the matrix
correction is activated.
7. Once the correction is activated, the result Correction result is
shown.
Note: This process must always be carried out in full to make sure the
matrix correction is completed successfully.
If a correction does not produce a successful result, calculations are made
with the previous correction.
The 1-point value correction offers the option of retrospectively
performing a matrix correction at one point.
1. Take several samples with different concentrations on various
days, preferably within one week. Analyze the samples in the
laboratory. During the time the samples are being taken, the
sample temperature should vary a maximum of 5 °C, as
temperature changes are not taken into account in the value
correction.
2. Make a note of the two values measured in the samples and
displayed for the parameters to be corrected (ammonium and
potassium values, or nitrate and chloride values)
3. Also note the laboratory values measured for ammonium or
nitrate.
These three values form the correction point.
4. From the values taken, select a correction point that lies in the
middle of the expected concentration range.
