LCR Meter 12 Ponits Frequency, 0.1% Accuracy, DCR Meter & Electrolytic Cap Mode, SCPI, TFT, USB，ET4402,Gray

The East Tester ET4402 is a high-precision benchtop LCR digital bridge designed for accurate component parameter analysis. Utilizing the automatic balance bridge principle, it offers a measurement frequency range of 100Hz to 20kHz with 12 fixed points. It delivers a basic accuracy of 0.1% and supports versatile measurements including inductance (L), capacitance (C), resistance (R), impedance (Z), and specialized modes for DC resistance (DCR) and electrolytic capacitors. Equipped with a 3.5-inch TFT LCD providing 5-digit readouts, it ensures clear visibility. The instrument features adjustable test levels (10mV-2000mV) and internal bias voltage (0-1500mV). Comprehensive connectivity includes USB Device, RS232, and Handler interfaces, supporting SCPI protocol for seamless system integration. It provides auto/manual ranging, open/short calibration, 5-bit comparator sorting with alarms, and data logging for max/min/average values. Ideal for R&D, incoming inspection, and production testing, it combines precision, flexibility, and user-friendly operation.
