Comprehensive Functionality: This digital multimeter offers a wide range of functions, including automatic identification of AC/DC voltage, resistance, capacitance, frequency, and diode testing. It also features continuity testing with a buzzer, making it an all-in-one tool for various electrical diagnostics True RMS for Accurate Measurements: Equipped with True RMS technology, the multimeter ensures precise and reliable readings, especially for measuring AC voltage and current, even in non-linear loads User-Friendly Design: The multimeter features an easy-to-read color display that clearly shows measurement results. The data hold function allows you to freeze the current reading on the screen for easier analysis, while the auto power-off function helps conserve battery life NCV & Live Wire Detection: Non-contact voltage (NCV) detection and live wire identification make this device ideal for safety and quick assessments. Simply bring it near a live wire, and it will alert you to the presence of voltage without direct contact Rechargeable and Durable: This multimeter comes with a built-in rechargeable battery, providing long-lasting power. The robust design ensures durability, while the included temperature detection feature adds versatility for environmental measurements Specifications: DC voltage: Range: 0~600V±0.001 (0.8%+3) / 1~600V±0.001 (0.8%+3) AC voltage: Range: 0~600V±0.001 (1.2%+5) / 1~600V±0.001 (1.2%+5) Resistance: 0.1Ω~10.00MΩ, resolution: 0.1Ω (accuracy±(1.2%+3)) / 10.00MΩ~60.00MΩ, resolution: 0.1Ω (accuracy±(2.0%+10)) Capacitance: 1nF~1.00mF, resolution: 0.001nF (accuracy±(3.5%+8)) / 1.00mF~60.00mF, resolution: 0.001nF (accuracy ± (4.5% + 10)) Voltage frequency: 10Hz~1mHz (ACV3~600V), resolution: 0.1Hz (accuracy ± (2.0% + 10)) Duty cycle: 0.1%~99.9%, resolution: 0.1Hz (accuracy ± (1.5% + 5)) Diode: Automatic identification of diodes less than 3V (LEDs below 3V can light up) Automatic shutdown: 5 minutes Battery: 800mAh
