To configure the factor Barrel temperature profile in the first step the barrel elements have to be defined which shall be included in the modification. Choosing them is done via the check boxes in the table rows Vary.

The barrel temperature profile can be set either by a value interval or by one single value.

A value interval is set by marking the radio button Set range. The lower limit of the interval is set over the addition of the input in the text field Delta -, the upper limit over the addition of the input in the text field Delta + and the selected barrel temperatures. The number of the interval steps can either be determined in the input field Steps or in the input field// Step width//. If the lower limit shall be less than / equal the initial value, a minus must be put in front of the value.

If a single value shall be set, the radio button Replace value must be marked; the value in the text field Offset is added on the selected barrel temperatures.

Via the check box Vary all experiments the user can choose if only the basic process or all processes contained in the experimental design shall be varied.
