Press Ilim key in order to reach menu for trip-out current selection and character of displayed part of leakage current
(resistive or capacitive). The same procedure as for Ilim selection at HV function applies.
To change U and T values press U/T key. Value T2 represent time from t1 to t2 and value T3 represent time from t2 to t3. (fig. 12).
Menu for selection and changing values is displayed, see the following figure:
