  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.
