The TT-2D is designed to test acoustic transducers for resonance over the frequency range of 500 Hz to 500 KHz. It can test all types of transducers, including transformer-coupled and magnetostrictive devices. The load characteristic (capacitive, resistive, or inductive) and impedance at resonance are displayed on the two line LCD display. The leakage resistance of the transducer can be measured and displayed over the range of 10 ohms to 5 megohms.
