ET432 Handheld LCR Digital Bridge 0.2% Accuracy 2.8-inch TFT LCD Screen 100Hz-100kHz for Component Testing

This ET432 handheld LCR digital bridge offers reliable measurement of resistance, capacitance, inductance, and impedance with a 0.2% accuracy level, making it a practical tool for electronics repair, component sorting, and quality checking. The 2.8-inch TFT LCD screen shows both main and sub parameters clearly with 5 digits each, so you can quickly read L/C/R/Z alongside X/D/Q/θ/ESR. With a frequency range from 100Hz to 100kHz across 4 test points, it covers a wide variety of passive components. The meter includes calibration functions, adjustable filtering, and deviation measurement to streamline your workflow.

Features and Construction

The ET432 is built around a robust measurement engine with several user-adjustable settings to improve accuracy and usability in different testing scenarios.

Measurement Parameters

Main parameters include inductance (L), capacitance (C), resistance (R), and impedance (Z). Sub parameters provide additional detail: reactance (X), dissipation factor (D), quality factor (Q), phase angle (θ), and equivalent series resistance (ESR). This dual-parameter display helps you evaluate component health beyond just a single reading.

Calibration and Filtering

Open circuit and short circuit calibration ensure the meter is zeroed correctly before each measurement session. The filtering function can be set between 1% and 50% with fixed points at 1%, 5%, 10%, and 20%, allowing you to stabilise noisy readings or increase measurement speed as needed.

Display and Interface

The 2.8-inch TFT LCD screen shows main and sub parameters simultaneously with 5-digit resolution. You can adjust backlight brightness for different lighting conditions and set an automatic shutdown time to save battery life. The interface supports both Chinese and English language selection, and USB Device communication allows data transfer to a computer.

Uses and Placement

This LCR bridge suits a range of electronic testing environments, from hobbyist workbenches to professional service centres.

Component Testing and Sorting

Use the deviation measurement mode to compare a component against a set nominal value and view the percentage difference on screen. This is useful for sorting resistors, capacitors, and inductors into tolerance bins or verifying that parts meet specifications before assembly.

Fault Finding in Circuits

By measuring L/C/R/Z and ESR, you can identify faulty capacitors with high ESR or out-of-tolerance inductors without desoldering them from the board in many cases. The 0.2% accuracy gives confidence in borderline readings.

Educational and Lab Use

With a frequency range up to 100kHz and multiple test points, the ET432 is suitable for teaching component behaviour or performing experiments in electronics courses. The included Kelvin test clamp and crocodile test clip make connection quick and secure.

Benefits and Buying Value

This handheld LCR bridge combines practical features with portability at a weight of just 0.5 kg, making it easy to move between workstations or take on site.

Portable and Self-Contained

The meter runs from a power supply via the included plug (UK type), and the compact design means it takes up little bench space. The adjustable backlight and auto shutdown help manage power consumption during long sessions.

Comprehensive Accessory Kit

You receive an instrument with colour box, USB data cable, manual, plug, short circuit piece, crocodile test clip, CD, and certificate of conformity. The Kelvin test clamp is particularly useful for low-resistance measurements where lead resistance must be eliminated.

Why Choose the ET432

Compared to the ET430 and ET431 models, the ET432 offers a 100Hz to 100kHz frequency range with 4 test points, giving you more flexibility for testing different component types. The 0.2% accuracy level and dual 5-digit display provide the detail needed for confident component evaluation without requiring a benchtop instrument.
