ZOYI High-Precision Handheld Bridge ZT-DQ02 LCR Lithium Battery Internal Resistance Meter 18650 Battery Tester

ZOYI ZT-DQ02 LCR and Battery Internal Resistance Meter

The ZT-DQ02 combines a handheld LCR bridge with battery voltage and internal-resistance measurement. Four-wire Kelvin measurement reduces lead and contact resistance when checking components or sorting rechargeable cells.

LCR Measurement

• Automatic, resistance, capacitance, inductance, impedance, electrolytic-capacitor and battery internal-resistance modes
• Primary parameters: L, C, R and Z; secondary parameters: X, D, Q, phase angle and ESR
• Resistance range: 0-10 MΩ
• Capacitance range: 0-100000 µF
• Inductance range: 0-100 H
• Test frequencies: 100 Hz, 120 Hz, 1 kHz, 10 kHz and 100 kHz
• Test levels: 0.1 V, 0.3 V and 0.6 V
• Best LCR accuracy: 0.3%; selectable series or parallel equivalent circuit

Battery Measurement

• Battery voltage range: ±100 V DC
• Internal resistance range: 0.1 mΩ to 200 Ω
• Internal-resistance accuracy: 0.5%; voltage accuracy: 0.2%

Operation and Package Options

The meter provides English and Chinese menus, open/short calibration, adjustable brightness, selectable measurement speed and configurable automatic power-off. It uses a built-in rechargeable battery with Type-C charging. Package 1 and Package 2 contain different accessory combinations; use the option selector and package images to confirm the included Kelvin leads and accessories.
