Description
TOA ZM-104A Impedance Meter
Product Details
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.
Features
- 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
