9 In 1 Digital Voltmeter Ammeter 10A/50A/100A Available Accurate Volt Current Power Meter for Auto Repair Electrical Projects

# Multifunctional DC Power Meter ### Key Features 1. 9-in-1 Real-time Monitoring: Track and display 9 core parameters simultaneously on a single screen, including voltage, current, power, impedance (not internal resistance), capacitance, energy, temperature, running time and charge percentage, no extra switching required. 2. HD Color Display: Equipped with a 0.96-inch high-resolution color screen with vivid color output and high contrast, delivering clear, easy-to-read readings both under bright direct sunlight and in low-light environments. 3. Customizable Calibration: To fit diverse application scenarios, we added adjustable voltage and current display settings, so you can fine-tune the displayed values to match your actual usage needs flexibly. 4. Practical Reset Functions: It supports one-click cumulative data reset to clear historical records and restart statistics whenever you need; plus the no-load auto-zeroing function automatically resets readings to zero when no load is connected, effectively avoiding cumulative errors. 5. Smart Power Management: After you manually set the full-charge and low-voltage thresholds, the device will intelligently calculate the remaining battery percentage, helping you optimize charging cycles and extend usage time of your powered devices.
