Description

HTC LCR‑4080Q Digital LCR‑Q Meter – High‑precision Multi‑function Capacitance & LCR Instrument

The HTC LCR‑4080Q is a professional‑grade digital LCR‑Q meter designed for accurate, reliable measurement of capacitance, inductance, and resistance, ideal for electronics labs, R&D facilities, service centers, electronic manufacturing and educational institutions. With a 19,999‑count LCD display, versatile frequency settings, open/short calibration, and rugged ergonomics, it’s engineered to deliver consistent, repeatable readings across a wide component range.

At the heart of the device is a capacitance measurement gear that covers from 20 nF up to 20 mF, supporting fine resolution down to 1 pF. This broad range makes the LCR‑4080Q perfect for testing everything from small ceramic capacitors to bulk electrolytic capacitors in circuits. Capacitance accuracy is typically within ±(2 % + 5) on the dedicated capacitance gear, ensuring dependable and repeatable results for component verification, design validation, and quality control.

The instrument supports automatic component identification (auto‑ID), which instantly recognizes whether the device under test is a capacitor, inductor, or resistor and switches to the appropriate measuring mode. For capacitance measurement this simplifies workflows, allowing engineers and technicians to focus on testing instead of manual setup.

In addition to capacitance, the LCR‑4080Q measures inductance from 20 mH to 2000 H with a reasonable resolution of 0.1 mH to 0.1 mF, and inductance accuracy of ±(2 % + 5). This makes it suitable for testing coils, transformers, chokes, and motors. The resistance range extends from 200 Ω to 20 MΩ, with a fine minimum resistance resolution of 0.01 Ω to 1 kΩ and accuracy of ±(1.0 % + 5)—excellent for checking resistors, wire continuity, and ESR in capacitors.

To maximize measurement flexibility, the device offers selectable test frequencies at 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz, allowing finer readings based on component characteristics. It supports both automatic and manual ranging, so users can let the instrument adjust itself or fix the measurement range as needed.

A built‑in open/short calibration function eliminates test lead errors—especially critical when measuring small capacitances or low inductance values—ensuring precise zero‑point correction before testing.

The dual‑line LCD display features a 19,999‑count main readout supported by a secondary 1,999‑count readout, combined with clear symbols for mode, polarity, test frequency, Q‑factor (quality), equivalent series resistance, and percentage errors. This layout provides a rich set of information at a glance, reducing reading errors and improving usability in busy work environments.

Weighing approximately 380 g and compact in its form factor (roughly 172 × 83 × 38 mm), the LCR‑4080Q is both lightweight and durable. The user‑friendly switch layout and ergonomic design handle regular field or bench usage confidently. The casing resists typical wear from falls, abrasion, or rough handling in workshop conditions, and the instrument is easy to grip and carry around.

Powered by two standard 1.5 V AAA batteries, the device offers around 50 hours of continuous use, minimizing downtime and reducing operating costs. Its low power draw makes it ideal for portable usage in field service or labs without dedicated power outlets. The electronics comply with EN 61326‑1 safety standards, so it meets accepted electromagnetic compatibility and environmental guidelines.

With a high 19,999‑count resolution, the HTC LCR‑4080Q delivers high precision even on small changes in capacitance or inductance. The count capability translates into precise measured values—for example, reading a 1 mF capacitor at multiple frequency points or comparing several capacitor batches. Accuracy figures of ±(1.0 % + 5) for resistance and ±(2 % + 5) for inductance/capacitance ensure consistent trust in each reading.
