1. Click on List.
2. Select the required measurement process.
• [Z]Z1 λ
1
{ [R]R1 λ
1
}: Zero measurement, repeated
single-wavelength measurement.
• [Z]Z1 λ
1
[R]R1 λ
1
: Zero measurement with subsequent
measurement on one wavelength.
• [Z]Z1 λ
1
[R]Z2 λ
1
{[R] R1 λ
1
}: Two zero measurements,
repeated measurement on one wavelength. For
example, zero measurement against air, zero
measurement against sample blank value, measurement
of sample.
• [Z]Z1 λ
1
[R]R1 λ
1
[R] R2 λ
1
: Zero measurement, two
measurements on one wavelength. For example, zero
measurement, measurement of sample with reagent 1,
measurement of sample with reagent 2.
• [Z]Z1 λ
1
Z2 λ
2
[R] R1 λ
1
R1 λ
2
: Two dual-wavelength zero
measurements, two dual-wavelength measurements of
sample.
3. Press OK.
4. Input the wavelength and press OK to confirm.
The wavelength is displayed in the measurement process.
5. Press Next.
6.1.2.3 Enter the calibration formula (evaluation formula)
The calibration formula (evaluation formula) defines the
calculation and display of intermediate and final results. The
previously defined elements of the measuring sequence are the
basis for calculating the concentrations.
Refer to Table 11 for detailed information on the Edit formula
keys.
Note: The evaluation formula is built up successively in the display in
accordance with the input.
Note: The key with the arrow deletes the last entered section of the
equation.
