  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, Test, 
   Scroll trough results and menus.
● Checks wiring integrity (LEDs).
● Auto off/auto ranging (software ranging). 
● Combined prospective short circuit current, loop,   
   individual wire and Earth Tester.
● Voltage test L-N and L-E.
● Loop test for L-E and L-N and PSC.
● Enables analysis of constituent components in L-E
   and L-N loops giving resistance of earth, neutral
   wire, live wire and transformer winding.
● Display can be customized for large orders.
