Viewing the Temperature Calibration Parameters

Temperature calibration is useful for experiments in which precise transition temperatures are essential. Select Cell/Temperature Table from the Calibrate menu and click on the Temperature page.

This window shows the temperature calibration table that the instrument applies to the collected data. One to five temperature calibration points (pairs of observed and correct temperature points) may be used. Temperature calibration is based on a run that heats a high purity temperature standard, such as indium, through its melting point. The observed and correct temperatures correspond to the experimental and theoretical transition temperature (e.g., melting point) of the calibrant respectively.

These calibration points are automatically updated in this window after temperature calibration has been performed, accepted, and saved using the Calibrate/Analysis function. Temperature calibration experiments are conducted with the instrument in the calibration mode, which ignores previous calibration factors.

NOTE: A multiple-point calibration is more accurate than a one-point calibration. A single-point calibration shifts the sample temperature by a constant amount. A two- or more-point calibration shifts the temperature by a constant amount below the first point, uses a smooth curve through the calibration points and maintains a constant temperature shift after the last point.

If these values are correct, select OK.

To manually edit these values:

1. Select the Reset button to remove all previously stored values.  

2. Enter the Observed and Correct temperature points in the table.

3. Select OK when all points have been entered to save the settings to the instrument.

NOTE: When temperature calibration is in effect, Temp in *C appears in the status line.  When it is not in effect, Temp in °C appears in the status line.
