ZOYI ZT-MD2 Review – Smart LCR Tweezers for SMD Component Testing
The ZOYI ZT-MD2 is a professional Smart LCR Tweezer designed for fast testing of SMD resistors, capacitors, inductors, ESR, diodes and PCB components. It is ideal for electronics repair, PCB diagnostics, laptop repair, drone electronics, RC electronics and workshop troubleshooting.
With 100kHz LCR measurement, automatic component recognition, ESR testing, signal generator, frequency sweep and USB-C charging, the ZT-MD2 is a compact but powerful tool for accurate SMD component analysis.
Why Use Smart LCR Tweezers?
Testing small SMD parts with normal multimeter probes can be difficult, especially with 0201, 0402 and 0603 components. The ZT-MD2 uses tweezer-style tips so you can hold and measure tiny components directly on a PCB or on the workbench.

ZT-MD2 vs ZT-MD1
| Feature | ZT-MD1 | ZT-MD2 |
|---|---|---|
| LCR Frequency | Basic LCR testing | Up to 100kHz |
| Component Recognition | Yes | Improved smart recognition |
| ESR Testing | Limited | Yes |
| Signal Generator | No | Yes |
| Frequency Sweep | No | Yes |
How to Test an SMD Capacitor
- Power on the ZT-MD2.
- Select auto mode or capacitance mode.
- Touch both ends of the SMD capacitor with the tweezer tips.
- Wait for the reading to stabilise.
- Compare the measured value with the marked or expected capacitance.
How to Measure ESR
ESR is useful for checking capacitor health. A capacitor may show the correct capacitance but still fail under load if its ESR is too high. With the ZT-MD2, simply select the correct measurement mode, connect the tweezer tips across the capacitor, and read the ESR value.
FAQ
Can the ZT-MD2 replace a multimeter?
No. It is designed for component testing and works best alongside a digital multimeter.
Can it test components on a PCB?
Yes, but surrounding components can affect readings. For critical measurements, test the component out of circuit.
Is 100kHz useful?
Yes. Higher-frequency testing is useful for small inductors, ceramic capacitors, RF circuits and more detailed component behaviour analysis.
