You can select one of the following temperature compensation methods:
• Nonlinear temperature compensation (nLF) according to EN 27 888
• Linear temperature compensation (lin) with adjustable coefficients of
0.000 ... 3.000 %/K
• No temperature compensation (---)
Application tips
Select the following temperature compensations given in the table according to
the respective test sample:
6.1.4 Setting the TDS factor
The factor to calculate the total dissolved solids is set to 1.00 in the delivery
condition.
You can adjust this factor to meet your requirements in the range 0.40 ... 1.00.
1. Select the measured parameter TDS with <MODE> .
2. Set the TDS factor with <
