What is the 'temperature coefficient' / how is it calculated?

With the power converter in a temperature test chamber with rated output load, make the following measurements.

Output voltage at 25oC ambient temperature
Set the chamber for maximum operating ambient temperature and allow the power converter to stabilize for 15 to 30 minutes. Measure the output voltage.
Set the chamber to minimum operating ambient temperature and allow the power converter to stabilize for 15 to 30 minutes.
Divide each percentage voltage deviation from the 25C ambient value by the corresponding temperature change from 25C ambient.

The temperature coefficient is the higher one of the two values calculated above, expressed as percent per change centigrade.
