4.4 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 4.5 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 %
/
K
l no temperature compensation
