FK909

CONTINUITY METER

The FK 909 gives a rapid and audible indication of resistances in home appliances and industrial wiring between 1 ohm and 500 KOhm. The circuit resistance forms part of an oscillator circuit which level and frequency is inversely proportional to the circuit resistance. At low resistance the both volume and audio frequency coming from the in-built speaker will be high. At higher resistances both volume and audio frequency will be lower.
