TOA ZM-104: Impedance Meter

The TOA Impedance Meter, ZM-104, has been designed to measure impedances in the speaker lines in sound systems. It is fully portable and is operated from internal batteries. This handy meter provides accurate direct readings in the manner of a circuit meter, simply by disconnecting the speaker line from the amplifier and connecting it to the measuring leads.

The range selector switch allows selection of three ranges, from five to one hundred thousand ohms.
