ZC2893A Impedance Tester

Using microprocessor control and digital measurement technology
Frequency and impedance dual display window
Use the constant current method to test. A total of five constant test currents
Built-in voltage-controlled oscillator, test frequency can be set arbitrarily
Three working modes: 400Hz/1kHz, arbitrary frequency and sweep frequency test
With sorting setting and discrimination indication function
Short-circuit clearing to eliminate test lead errors
Suitable for fast testing of the speaker and magnetic head impedance and characteristic analysis of impedance frequency
