DF2893 Impedance Tester

u DF2893A Fully Digital Impedance Tester.

u DF2893B Digital Speaker Impedance Tester.

u DF2893C Digital AC/DC Impedance Meter.

u Microprocessor-controlled, fully digital functions.

u Frequency and impedance displayed simultaneously in digital format.

u Utilizes constant current method for testing, with five AC constant test current ranges.

u Built-in sine wave voltage-controlled oscillator, test frequency can be arbitrarily set.

u 400Hz/kHz arbitrary frequency, sweep frequency testing with three frequency operation modes.

u Features sorting settings, judgment indication, short-circuit zeroing, and pre-calibration functions.

u Suitable for rapid testing of speaker and magnetic head impedance, and impedance frequency characteristic analysis.
