5 Setting the measuring mode
You can make the following settings in the Device / Set menu (default setting
in bold):
TDS factor The factor to calculate the total dissolved solids is set to 1.00 in the factory.
You can adjust this factor to meet your requirements in the range of 0.40 to
1.00. The factor is set in the menu for the parameter, TDS.
Temperature
compensation
The calculation of the temperature compensation is based on the preset
reference temperature, 20 °C or 25 °C. The reference temperature is shown
on the display.
-Temperature
coefficient
The temperature coefficient for the linear temperature compensation is set to
2.000 %/K in the factory. You can adjust this factor to meet your requirements
in the range 0.000 ... 3.000 %/K. The factor is set in the menu for the setting
of the temperature compensation.
Note
More information on conductivity measurements is given in the WTW
conductivity primer.
