When a temperature grade is set (Centigrades per minute), it is unadvisable to set a humidity grade.
The two quantities interfere with each other and therefore the temperature grade would be observed,
whereas the humidity grade would not.
The humidity grade should, therefore, be set only when the temperature is kept constant.
Please refer to the MOLLIER diagram to establish the test logic to be carried out for both temperature
and humidity.
