1826 NA Digital Electrical Network Analyzer

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 reisistance that the earth current will need to go through as an earth fault occurs. (you do not need to add all the bonding points and connection paths resistances)
Displays voltage supply at the transformer (Line to Neutral), without drawing any current.
Measures the Impedance of the Line itself, so you can analyze and differentiate between the multiple paths of the wiring.
Measures the Neutral Impedance.
Checks wiring integrity (LEDs).
Auto-off/auto-ranging (software ranging).
Microprocessor controlled.
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.
EN/IEC 61010-1 CAT III 300V
