Zoyi DQ-02 LCR Meter and Battery Analyser
Product Resources
Unlock Accurate Component & Battery Insights. The Zoyi ZT-DQ02 is a handheld, high-precision digital LCR bridge designed for professionals and enthusiasts who demand accuracy in measuring resistances, capacitances, inductances, and their characteristic parameters. It also integrates a dedicated function for precise battery voltage and internal resistance measurement, making it a truly versatile tool for your test bench or tool bag.
Key Features & Benefits:
-
Comprehensive LCR Measurement:
- Accurately measure main parameters: Inductance (L), Capacitance (C), Resistance (R), and Impedance (Z).
- Analyze sub-parameters: Reactance (X), Dissipation Factor (D), Quality Factor (Q), Phase Angle (θ), and Equivalent Series Resistance (ESR) to fully characterize components.
- Selectable test frequencies (100Hz, 120Hz, 1KHz, 10KHz, 100KHz) and levels (0.1V, 0.3V, 0.6V) for diverse testing needs.
-
Highest LCR measurement accuracy of 0.3%.
-
Dedicated Battery Health Assessment:
- Precisely measure battery voltage (up to DC 100V) and internal resistance using a dedicated aviation plug input for secure connections.
- Achieve battery internal resistance accuracy of 0.5% and voltage accuracy of 0.2%.
-
Enhanced Accuracy & Usability:
- Utilizes four-wire measurement input for significantly improved LCR measurement accuracy and reliability.
- Clear 2.8-inch TFT high-definition display (320×240) shows primary, secondary parameters, and settings simultaneously.
- Adjustable measurement speeds (slow, medium, fast).
- Features Auto, Series, and Parallel equivalent modes.
- Data Hold, Recording Mode (PC synchronization via SCPI), and Tolerance Mode for batch screening.
