        1826 NA   Loop Testers
        1826 NA
         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 is an earth fault occurs. (you do not need to add all the bonding points and connection paths resistances)
         Dispalys 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 analyzes and differentiate between the multiples paths of the wiring.
         Measures the Neutral Impedance.
         Single One Smart Push button operation; ON, Test, Scroll through results and menus.
         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 consituent components in L-E and L-N loops giving resistance of earth, neutral wire, live wire and transformer winding.
         Test leads, shoulder belt user is manual, batteries included.
         The Display can be customized for large orders.
         CAT III 300V.
         The 1826 NA is the first portable electrical network analyzer. It has a built in Earth tester which does not require the use of poles or long wires. This instrument is useful for fault-finding or commissioning of electrical installations.
         Differentiation between the Line (hot), Neutral and Earth (ground) path by reading their values has never been so easy. Bad contacts, old wiring or bad earth path are quickly identified. Faulty electrical network can be resolved in a fraction of the time normally required using conventional equipment.
         Down time due to a faulty electrical network is minimal as the fault can be identified and diagnosed quickly. Find which wire need to be attended to and why (find those old wires with high impedance before a fire starts, and replace them). The complete electrical network can be analyzed by scrolling though the results.
