Once the user depress the button, power is applied to the tester’s circuit. The PE-425 is a new type of Multifunction Instrument which test and report on all important components of a basic electrical network. - Page 10 USER’S MANUAL. PE-425 The PE-425 is the first portable real electrical network analyser. It has a built-in Earth tester which does not requires 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.
