Voltmeter Ammeter 12V DC 6.5-100V 20A, Voltage Meter Wattmeter Tester Voltage Current Power Energy Digital LCD Energy Meter DC20A

• 【4-in-1 Multimeter】This digital DC voltmeter/ammeter is used to measure voltage, current, electrical energy, and active power of electrical devices. It has passed CCC, FCC, and CE certifications.
• [Measurement Range] Voltage test range: 6.5~100V DC, current test range: 0~20A, active power: 0~2kW, electrical energy test range: 0~9999kWh. Please do not exceed the rated parameters. 20A is only for For short loads, but not suitable for continuous operation. If the continuous output exceeds 15A, it is recommended to upgrade to the 50A version.
• 【More functions】 Large LCD screen with backlight; voltage alarm function; energy reset function; power-off data storage; built-in shunt, no external shunt required.
• 【Wide application】This DC voltmeter is suitable for indoor use and cannot be used outdoors. Can be used to monitor batteries, solar systems, Electric bicycle generators and other fields. The load cannot exceed the rated voltage and current.
• 【Package】Package: 1 * DC Multimeter, 1 * User Manual. Note: Please connect according to the wiring diagram we provide. If you would like to try another connection, please contact us first. Otherwise, an incorrect connection can cause burning or product malfunction.

Product Description Its function is to measure electrical parameters (voltage, current, active power, electrical energy). Voltage alarm function (overvoltage alarm threshold, backlight, and flashing voltage indicator during alarm). Power key reset function. Stores data in case of power failure. Large LCD screen (simultaneously displays voltage, current, active power, and electricity) Backlight function. Backlight control: Press this button to turn the backlight on or off. Saves the backlight state when powered off. Reset power: Press and hold for 5 seconds until Release the button after the number flashes and press the button again. The power value will be cleared and the device will exit the reset flashing state. If you do not want to clear the value, press and hold the button again. Press and hold for a few seconds until the number stops flashing, indicating that the power value has not been cleared and the device will exit the reset state. Voltage Alarm: Press and hold the button until the power display area appears. Press 'SET', release the button. The current high voltage alarm value will be displayed in the voltage area, the current low voltage alarm value will be displayed in the current area, and the last digit will begin flashing. Press the button to set the value. No operation within 3 seconds will automatically change the number; then press the key to adjust the value. Voltage alarm threshold setting range: 6.5V ~ 99.9V. After setting, press and hold. Press and hold until the screen displays "PASS". Learn More Wiring Diagram Notes: This module is suitable for indoor use only; please do not use it outdoors. The applied load must not exceed the rated voltage and current. The wiring sequence must be correct.
