FEATURES ● Microprocessor-controlled.● Measures Earth Resistance without the need for    poles in the ground or external measuring wires.● Earth measurement uses the real earth current path    and the current generated by the electric network,    without the need for any disconnection.● The Earth Resistance displayed is exactly the earth    resistance that the earth current will need to go    through if an earth fault occurs. No need to add all    the bonding points and connection paths resistances.● Displays voltage supply at the transformer (Line to   Neutral), without loading the transformer.   Displays voltage between Line (Phase) and Earth      (Ground), without drawing any current.● Measures the impedance of the line itself so you can    analyze and differentiate between the multiples paths    of the wiring.● Measures the Neutral Impedance.    Single one smart push button operation; ON,...
