Temperature errors
The internal lead wire causes a systematic measure-
ment error in the versions 902006/54 and 902006/65.
This depends on both the nominal length (NL) as well as
the measured temperature. In the table, the error is
shown per 100 mm insertion length (EL) depending on
the temperature measurement.
Lead wire resistance of a 0.5 mm NiCr wire per 100 mm
insertion length (EL) (double wire length).
The specifications are to be viewed as reference values.
