Menu Explanations
3.4 Set Time
Adjust date and time.
4 Settings
4.1 Sensors
Photometer Enter the reference values of the verification cuvettes according to
the enclosed calibration certificate.
Range: 0.000–2.000
Electrode pH
Filter time
constant
Used to damp noisy signals. The higher the filter time constant, the
slower the system reacts to changes of the measured value.
Range: 5–300 s
Temp. Comp. Choose the compensation model which fits best to your application.

None : no temperature compensation.

Nernst : for potable water, waste water, swimming pools.

Coefficient : for special applications.
Range: −0.100–0.100 pH unit per °C
NOTICE: For this setting the unit °C is always used, regardless
of the setting under 4.3 Units, p. 44 .
Standards A temperature curve is programmed for SWAN standard 1, pH 7
and SWAN standard 2, pH 9. If you want to use your own standards
you can readjust the temperature curve according to your stan

dards.

Standard 1 : Assign the measured pH value to the according
temperature from 0–50 °C in steps of 5 °C.

Standard 2 : Assign the measured pH value to the according
temperature from 0–50 °C in steps of 5 °C.
