Description

Product Overview

The ERYUE YR2050 Milliohm Meter is engineered for precision in low‑resistance testing, offering a four‑wire measurement method that eliminates lead resistance and improves accuracy to the micro‑ohm level. Housed in a rugged yet lightweight compact chassis measuring 4.72 x 2.36 x 1.57 inches and weighing just 10.6 ounces, the device is built for portability without sacrificing durability. Powered by an internal rechargeable battery, it operates battery‑free for extended sessions, delivering consistent performance across a temperature range of 10 °C to 40 °C. The meter features a clear LCD display, intuitive navigation keys, and a robust metal probe set that can handle wire, transformer, motor and large inductance testing. With a best‑seller rank of #25 in the Ohmmeters category, the YR2050 has earned a reputation for reliable low‑resistance measurement in industrial and scientific environments.

Usage

Designed for field engineers, maintenance technicians, and laboratory specialists, the YR2050 excels in a variety of real‑world scenarios. Whether you are verifying the continuity of motor windings, checking the resistance of power cords, or assessing transformer windings, the meter provides instant, repeatable results. Its handheld form factor allows users to carry it on‑site, making it ideal for routine preventive maintenance, troubleshooting of electrical equipment, and quick quality checks during manufacturing. The device’s ability to measure resistances in the milliohm range also supports applications such as cable length verification, cross‑sectional area calculations, and current‑sense resistor validation. Because it does not require external batteries, users can focus on testing without worrying about power interruptions.

FAQ

Can the YR2050 measure battery voltage?

No. The meter is specialized for low‑resistance (milliohm) measurements and does not include a battery voltage testing function.

What is the maximum resistance the meter can accurately measure?

The device is optimized for resistances up to a few ohms, providing the highest accuracy in the milliohm to low‑ohm range.

Is the meter suitable for measuring large inductors?

Yes. While it cannot test battery voltage, it can accurately assess the resistance of large inductance components such as transformers and motor windings.

How do I set upper and lower limits for transformer testing?

Enter the normal mode, open the limit settings, input the desired resistance range, and the meter will alert you if the measured value falls outside those bounds.

What accessories are included with the YR2050?

The package contains the handheld meter, a set of four‑wire probes, a protective case, and a quick‑start guide to help you begin testing immediately.
