Audio Impedance Meter
Powerful compact unit measures impedance at 100Hz, 330Hz, 1KHz and 10KHz, providing accurate measurement of a single loudspeaker, an entire distributed system, or individual components such as resistors, capacitors and inductors. 3-1/2 digit LCD display clearly shows system impedance with accuracy of up to 0.1Ω. On 70V distributed systems, it calculates the wattage rating of the entire system. Because an audio frequency test signal is used, measurements can be taken of impedance of matching transformers, switchers and volume controls, with far more than with conventional DMM’s. Banana test leads included. Requires eight “AA” batteries (292-020), not included.
