Selection constant | ISO / DIN
constant
The temperature compensation is carried out with the value entered
for the temperature coefficient.
ISO / DIN
For ground water, spring water and surface water, the temperature
coefficients according to standard ISO 7888:1985 (German version:
DIN EN 27888:1993) are stored in the system.
Temp. coefficient
This parameter can only be edited with Temp. compensation = con-
stant.
Temperature coefficient belonging to the reference temperature entered
above. With this temperature coefficient, the conductivity is converted to
the reference temperature.
Input range 0.00 - 9.99 %/°C
Default value 0.00 %/°C
29.9.2 Standard addition
Under [Standard addition], the parameters for the concentration mea-
surement by means of standard addition are defined. This button is avail-
able only with the MEAS Conc command (concentration measurement).
Addition
Selection of the addition mode.
Selection off | auto | auto dos | manual
Default value off

The concentration measurement is carried out without standard addi-
tion, i.e. as a direct measurement.
auto
The standard solution is dosed automatically. The individual volume
steps are calculated in the way that a certain voltage difference is
reached. This voltage difference (Delta U) is defined under Standard
addition Dosing device.
auto dos
The standard solution is dosed automatically. The individual volume
steps are defined under Standard addition Addition increments.
manual
The standard solution is dosed manually. The individual volume steps
are defined under Standard addition Addition increments.
