Select „Active power reverse “ and „Overshooting“ in the menu items „Measured
Quantity“ and „Measurement Method“. Open the menu item „Settings“ and set a
checkmark in the box „Display additional settings“ to configure threshold, pickup delay

during a failure of the measuring voltage, it is useful to activate a blocking in this case.
