The 2726 NA is the first portable real 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. Differentiating between the Line (hot), Neutral and Earth (ground) path by reading their values has never been easier.

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 needs 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 through the results. It has a built-in loop impedance and prospective short circuit tester as well as a voltmeter.
