Setting up the temperature compensation TC

The calculation of the temperature compensation is based
on the preset reference temperature, Tref 20 or Tref 25 (see
section 4.7 C
ONFIGURATION
You can select one of the following temperature compensa-
tions:
l Non-linear temperature compensation "nLF"
according to DIN 38404 or EN 27 888
l linear temperature compensation "Lin" with a coeffi-
cient that can be set in the range 0.001 ... 3.000 %
l no temperature compensation
Note
Select the following temperature compensations to work
with the test samples given in the table:
Test sample
Natural water
(ground water,
surface water,
drinking water)
Ultrapure water
Other aqueous
solutions
Salinity
(seawater)
