WELT-010 Wireless Electrical Tester / Analyzer The WELT-010, Bluetooth Low Energy Wireless Electrical Tester/Analyzer is designed to inspect and analyze wiring compliance to electrical code such as voltage drop under different load, find problem with splices, wiring connections and conductor quality based on impedance analysis. Connection and wire impedance is calculated based on voltage drop and real current value which is measured during voltage drop test. Also, The WELT-010 is able to perform electrical socket wiring connection verification (incorrect wiring), AFCI test (series), 30mA ground test, standard GFCI test, measure AC voltage and current. All of mentioned parameters directly influence to safety and performance of the electrical system. WELT-010 use iPhone or iPad as command and display unit that give new flexible functional opportunity. Main Functions Measuring Voltages (line to neutral, line to ground and neutral to ground) Measuring external RMS current and power. Verifies wires connections on the electrical socket (incorrect wiring). Measuring voltage drop under different load (5A, 10A, 15A and 20A) with measuring of real load current (without trip circuit breakers or blow fuses during tests). Real impedance calculation and indication based on measured load current GFCI test AFCI Series test 30mA ground test
