1. Optimize the
baseline setting with
the aid of the
adjustment system.
How to set your baseline:
Place two empty crucibles on the sample carrier.
Check to see that the sample carrier is centered with the furnace opening.
If it is not, center the sample carrier using the two micrometer screws.
For the subsequent baseline optimization, it is usually only necessary to adjust the sample carrier
in the direction of the z axis.
Establish the measurement parameters for the sample measurement(s) to follow (temperature
program, sample chamber atmosphere, etc.).
Start the measurement.
Observe the course of the baseline (DSC signal).
If the baseline deviates in the exothermal
direction, this means that the sample is too warm. Correct the position of the sample crucible by
rotating the front micrometer screw clockwise. The sample crucible moves toward the back.
The DSC signal moves in the direction of the zero line.
If the baseline deviates in the endothermal
direction, this means that the sample (front crucible) is too cold. Correct the position of the
sample crucible by rotating the front micrometer screw counterclockwise. The sample crucible
moves toward the front. The DSC signal moves in the direction of the zero line.
