ET4501 Benchtop LCR Meter Digital Bridge, High Precision 0.1% Component Tester with Electrolytic Capacitor Mode, 10Hz‑10kHz Frequency, Open/Short Calibration, USB RS232 Support SCPI

The ET4501 Benchtop LCR Digital Bridge is a high-precision component tester designed for resistors, capacitors, inductors, and especially electrolytic capacitors. Adopting the automatic balance bridge principle, it provides 0.1% high accuracy and a wide frequency range from 10Hz to 10kHz. It supports precise measurement of L/C/R/Z/DCR/ESR and includes a dedicated electrolytic capacitor mode with adjustable DC bias, ensuring stable and accurate results for polarized capacitors. The 3.5-inch TFT LCD displays clear 5-digit readings for easy operation. Open/short calibration effectively reduces errors caused by test leads and fixtures. This tester features auto/manual ranging, a 5-bin comparator with alarm, and data statistics for max/min/average values. Equipped with USB, RS232, and Handler interfaces, it supports SCPI remote control and automated production testing. Ideal for laboratory, factory QC, production line, and electronic repair, the ET4501 delivers stable performance, high efficiency, and professional accuracy for all your component measurement needs.

• Before use, the instrument requires open and short calibration to minimize measurement errors caused by the test fixture.
