TEMP. COMP.
This menu allows to set up the temperature
compensation.
MEASURE
:
- No
- Pt
Choice of a temperature
measurement with or without
Pt100/Pt1000.
TYPE
:
- Auto.
- Manual
Choice between an automatic or a
manual temperature
measurement.
TEMP.
:
XX °C Possibility to enter the sample
temperature in a manual
compensation.
COMP.
:
- NERNST
Choice of the temperature
compensation type :
- linear compensation
(0.1984 mV/°C).
- Pure - compensation according to the
ultrapure water curve.
- Matrix 1
- compensation according to the
sulphate curve (4.84 mg/l
corresponds to a pH 4.0 to 25°C).
- Matrix 2
- compensation according to the
ammoniac/hydrazine curve (0.272
mg/l ammoniac + 20 µg/l
corresponds to a pH 9.0 to 25°C).
- Matrix 3
- compensation according to the
ammoniac / morpholine /
hydrazine curve (1.832 mg/l
ammoniac + 10 mg/l morpholine +
50 µg/l hydrazine corresponds to
a pH 9.6 to 25°C).
- Matrix 4
- compensation according to the
phosphate curve (3 mg/l
phosphates + 0.3 mg /l
ammoniac).
Coeff. - adjustable coefficient (pH/10°C)
∆
: XX In the case of a programmable
coefficient, possibility to enter the
value of the coefficient (value in
pH/10°C or pH/18°F).
