10 Configuration
For configuration of the device press
-key for 2 seconds.
Choose between the individual values that can be set by pressing the
- key again.
The individual values are changed by pressing the keys
or
.
Use
to leave configuration and to store settings.
’t.Cor’:
Selection of Temperature Compensation
off:
no temperature compensation selected
nLF:
non-linear temperature compensation for natural water
acc. to EN27888 (DIN 38404).
to measure ground water, surface water, drinking water and purest water
Lin:
linear temperature compensation
for other aqueous solutions
For TDS value measurements, non-linear temperature compensation for natural water is used (ref-
erence temperature = 25°C).
To measure salinity the instrument automatically switches over to the non-linear temperature com-
pensation acc. to
IOT
(reference temperature = 15°C).
’t.Lin’:
Setting of Temperature Coefficient
(only when t.Cor = Lin)
0.300 … 3.000:
Temperature compensation coefficient in %/K.
’t.rEF’:
Selection of Reference Temperature
(only when t.Cor = nLF or Lin)
20°C / 68°F:
reference temperature 20°C (68°F)
25°C / 77°F:
reference temperature 25°C ( 77°F)
’C.tdS’:
Setting of TDS-factor
0.40 … 1.00:
calculation factor for TDS-measurements
The calculation factor depends on the composition of the medium and has to be
determined for each type of water.
Displayed value = Conductivity [µs/cm, NLF-compensated at 25°C] * TDS-factor
’SCL’:
Setting of Scale Correction of Measuring Cell
0.800 … 1.200:
scale correction of measuring cell
The cell constant may change due to natural ageing or depositions at the fixed
measuring cell. In case you have an accurate reference liquid, you may adjust the
device by changing the scale correction accordingly.
Factory setting of the scale correction is 1.000.
