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.   (you do not need to add all the bonding points and    connection paths)● Displays voltage supply at the transformer(Line to   Neutral), without loading the transformer.● Single one smart push button operation; ON, Scroll   through results and menus.● Checks wiring integrity (LEDs).● Auto-off / Auto-ranging (software range).● Color-coded test leads.● Combined prospective short circuit current, loop, and   earth tester.● Loop test for L-E and PSC between L-N.● Voltage test L-N.● Display can be customized for large orders.    ...
