Brand New LFG-200 is a low frequency generator which is used as a built-in device in the ETL-series cable fault locators. Load matching is done automatically. The main parameters, such as output power, load impedance, selected frequency are shown on an OLED display. If the load is higher than 1000 Ω, LFG automatically switches into the output voltage setting mode. The output overload protection will trip when operating on short-circuit loops (lower than 0.5 Ω).
