TOA ZM-104A IMPEDANCE METER
A portable analogue meter that measures loudspeaker impedance (at 1kHz) in three ranges (5-1,000, 50-10,000 and 500-10,000 ohms) with a clear analogue display. Simply disconnect the speaker line from the amplifier, connect the meter across the line and read the impedance. Battery life approx 30 hours continuous use (at first range, 60 hours at higher ranges). Supplied complete with carrying-case, test leads and impedance power chart. Dimensions: 120 x 220 x 63 (w x d x h) mm including case. Weight less than 1kg including 4 x AA batteries (not supplied).
