If a value interval shall be set, the radio button Set range has to be marked. The lower limit of the interval is set in the text field From, the upper limit in the text field To. The number of interval steps can either be determined via the input field Steps or via the input field Step width.

If a single value shall be set, the radio button Replace value has to be marked; the value is entered in the input field New value.

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 by varied.
