Note
The measuring method can only be started if Ref. temp. , Start temp.
and Temp. interval are selected so that the reference temperature cor-
responds to the nominal temperature of a measuring point: Ref. temp.
= Start temp. + x* Temp. interval
6 Warm or cool the test sample to the start temperature Start
temp. .
As soon as the temperature of the measuring point is achieved
and a stable value is recognized, the measurement is automat-
ically started and the dataset stored.
After the measurement, a piece of information about the next
measuring point with the relevant nominal temperature is dis-
played and the temperature difference between the current
temperature and the nominal temperature.
7 Slowly warm or cool the test sample until the end temperature
End temp. is achieved.
Each time the nominal temperature for a measuring point is
reached a dataset is stored.
The corresponding calibration record with the determined tem-
perature coefficients is displayed at the end of the calibration.
If the calibration is successful, the determined temperature
dependency for the
TC nLin2 method is stored and used for fur-
ther measurements with this method.
8 Confirm the record with [Continue] .
[nLin2] is displayed in the status line of the measuring channel.
