approx. > 5 sec. until the  symbol appears on the display. Check the connecting line
of the test object by bending it over the entire length in order to detect weak points or
a break of the protective conductor. The BENNING ST 710 continuously records the
current measured value on the display and stores the maximum value in the memory. By
pressing the key 2 again, the measurement is carried out with reversed polarity. Press
