Key Features
1. Advanced LCR Measurement Capabilities
The ZOYI ZT-DQ02 offers full LCR testing functionality, capable of measuring:
-
Inductance (L): from microhenries (µH) to henries (H)
-
Capacitance (C): from picofarads (pF) to millifarads (mF)
-
Resistance (R): from milliohms (mΩ) to megohms (MΩ)
Using an intelligent auto-range system, the meter automatically selects the optimal range for each component, ensuring accurate results without manual adjustments. This feature makes it ideal for both beginners and professionals who require precise, quick, and reliable readings.
2. Integrated Battery Tester Function
Unlike standard LCR meters, the ZT-DQ02 includes a dedicated battery test mode that can measure both voltage and internal resistance (ESR) of various batteries. This feature is invaluable for:
-
Checking battery health and state-of-charge
-
Evaluating rechargeable batteries (Li-ion, NiMH, NiCd)
-
Diagnosing degraded or faulty power cells
By assessing internal resistance, users can identify batteries that appear to have normal voltage but are failing under load—something a regular multimeter cannot detect.
3. True RMS and High Accuracy Measurements
Equipped with high-precision ADC and DSP circuitry, the ZT-DQ02 ensures consistent accuracy across all measurement types. It supports both auto and manual range selection, along with a True RMS measurement mode that ensures reliable readings even for non-sinusoidal waveforms.
With accuracy typically within ±0.5% for resistance, ±1.0% for capacitance, and ±1.5% for inductance, this LCR meter is suitable for component validation, production testing, and repair diagnostics.
4. Large LCD Display with Backlight
The bright, high-contrast LCD display provides clear, easy-to-read measurement results even in dimly lit environments. The layout includes dual display lines, enabling simultaneous viewing of primary and secondary parameters such as value and measurement mode.
A backlight button allows you to work comfortably in low-light conditions, making the ZT-DQ02 perfect for field technicians and on-site service engineers.
5. Ergonomic and Portable Design
The handheld, compact form factor of the ZOYI ZT-DQ02 is designed for comfort and portability. The anti-slip grip and balanced weight distribution allow single-hand operation, while the durable ABS enclosure provides protection against drops and daily wear.
Lightweight yet sturdy, this meter easily fits into toolkits, making it an essential companion for on-the-go engineers and repair professionals.
6. Smart Auto Power-Off & Energy Efficiency
To conserve battery life, the ZT-DQ02 includes an auto power-off function that activates after a period of inactivity. Users can also manually disable this feature for extended testing sessions. The meter runs on standard AA batteries, which are easy to replace and widely available.
7. Multiple Test Frequencies
The LCR measurement function allows the user to select different test frequencies (100Hz, 120Hz, 1kHz, 10kHz) to better suit the type of component being tested. This flexibility provides more accurate readings for components across different operating conditions, from audio circuits to power supply filtering applications.
8. Open-Short Compensation
To minimize measurement errors caused by test leads and parasitic capacitance or inductance, the ZT-DQ02 includes Open-Short calibration. This professional-grade feature ensures highly accurate measurements, particularly when working with low-impedance components or very small capacitances.
Application
The ZOYI ZT-DQ02 is engineered for versatile testing scenarios and professional applications across multiple industries:
-
Electronics Design & Repair: Ideal for verifying passive components before integration.
-
Battery Maintenance: Accurately tests voltage and internal resistance for consumer and industrial batteries.
-
Educational Labs: Perfect for teaching electronic fundamentals in universities or training centers.
-
Production Testing: Efficient for incoming inspection of passive components and batteries.
-
Field Diagnostics: Portable design makes it suitable for on-site troubleshooting and equipment maintenance.
Ease of Operation
The user interface of the ZT-DQ02 has been designed with simplicity and speed in mind. The large selector dial and tactile buttons make it easy to switch between measurement modes. Clear icons and parameter labels help even beginners achieve professional results quickly.
The auto-hold function freezes the latest reading for convenient documentation, and the data retention feature ensures no loss of results when switching modes.
Safety and Reliability
Engineered to meet international testing standards, the ZT-DQ02 incorporates built-in protection circuits that guard against overvoltage, overload, and polarity errors. The test ports are clearly marked for safety, reducing the chance of incorrect connections during measurement.
