Description
The ZOYI ZT‑MD1 Digital LCR Tweezer Meter is a compact, high-precision tool designed to revolutionize electronics testing, mobile repair, and PCB troubleshooting. With its innovative tweezer-style design, this smart meter makes identifying and measuring SMD resistors, capacitors, and inductors faster and more accurate than ever. Beyond basic LCR measurements, the ZT‑MD1 also supports diode, continuity, low-voltage DC/AC, and frequency testing, making it an indispensable tool for professional technicians, repair shops, and electronics enthusiasts.
Compact Tweezer Design for Efficient SMD Testing
One of the standout features of the ZT‑MD1 is its integrated tweezer-style tips, enabling direct contact with SMD components without the need for separate probes. This design allows you to quickly test components on PCBs or reels without soldering, significantly speeding up troubleshooting and quality checks. The pen-like form factor ensures one-handed operation and portability, perfect for both bench use and fieldwork.
Auto Identification and Smart Measurement
The ZT‑MD1 features automatic component identification for resistors, capacitors, and inductors. Once a component is placed between the tweezer tips, the meter instantly recognizes its type and selects the appropriate measurement parameters. This auto-ID function eliminates guesswork and reduces testing time, allowing technicians to focus on repair and analysis rather than setup.
High-Precision LCR Measurements
Designed for precision, the ZT‑MD1 provides accurate readings across a wide range of resistances, capacitances, and inductances. Typical accuracy reaches ±0.5% for mid-range measurements, ensuring reliable data for both professional and hobbyist applications. Selectable AC test frequencies of 100 Hz, 1 kHz, and 10 kHz allow detailed characterization of components, including small SMD capacitors, larger electrolytics, and inductors or coils of varying sizes.
The meter also calculates ESR (Equivalent Series Resistance) and Q factor, providing deeper insights into component quality and health—an essential feature for identifying aging capacitors or verifying coil integrity.
Versatile Measurement Functions
In addition to LCR testing, the ZT‑MD1 supports multiple other measurement functions:
-
Resistance (R): Measures from a few ohms up to megaohms, auto-ranging for convenience.
-
Capacitance (C): Accurately measures small SMD capacitors in the picofarad range up to large electrolytics in the microfarad range.
-
Inductance (L): Measures small SMD inductors to larger coils, including Q or D factor readings.
-
ESR / Quality Factor: Uses AC excitation to assess capacitor and inductor quality for precise evaluation.
-
Diode Test: Checks forward voltage for standard and small signal diodes.
-
Continuity: Audible beep quickly detects open circuits or shorts.
-
Voltage Measurement: Low-voltage DC/AC measurement for quick verification near the tested components.
-
Frequency Measurement: Measures signal frequencies up to 10 kHz and supports selectable LCR test frequencies.
These versatile capabilities make the ZT‑MD1 more than a basic tweezer meter—it’s a compact lab-grade instrument designed for serious electronics work.
OLED Display and User-Friendly Interface
The ZT‑MD1 is equipped with a high-contrast OLED screen that clearly shows the measured value, unit, mode, and secondary parameters such as Q factor or ESR. The intuitive button interface allows quick selection of modes and test frequencies, ensuring efficient operation even when working in tight spaces or poorly lit environments.
Rechargeable Lithium Battery
Powered by a built-in 400 mAh lithium-polymer battery, the ZT‑MD1 offers long runtime and standby, eliminating the need for frequent battery changes. It charges conveniently via a low-voltage USB input (depending on the package), making it practical for extended use in workshops, repair labs, or on-site diagnostics.
