If the temperature is measured by external cold junction com-
pensation, a second thermocouple of the same type is re-
quired, which is connected in series with the first one. The po-
larity is selected so that the thermoelectric voltages subtract
each other. The second thermocouple is set to a fixed refer-
ence temperature ϑ
r
(mostly ϑ
r
= 0°C). The data logger then
calculates the temperature at the measuring position by means
of the linearisation curve as ϑ
x
= Lin(U
x
+Lin
-1
ϑ
r
). The data log-
ger will be informed about the reference temperature ϑ
r
via the
configuration software (“cold junction temperature”).
