Audio Impedance Meter with Overload Protection
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.
This model ZM1P
has all the features of the original ZM1, but adds an overload protection circuit that prevents the meter from being damaged by amplifier output overloads up to 120VAC. It also features a tone generator to improve system testing and performance.Specifications:
