ZM-104A

Impedance Meter

ZM-104A

The TOA ZM-104A Impedance Meter can measure the rough impedance value of speaker lines easily in the same manner as a circuit tester measures resistance.

For easy and exact measurement of speaker impedances including long cable length
Battery driven for mobile use (4 Mignon (AA) batteries)
One set of batteries for 30 - 60 hours operation time (depending on the measurement range)
Graphic conversion table impedance-power
Oscillator generates 1 kHz frequency
Measurement range of 5 to 100 kΩ
Comes with a case and one set of test leads
