VOKTTA | DC 0-30V Ultra-thin Mini Digital Voltage Power Meter With 0.5 Inch OLED Display Screen 1-6S Adjustable Percentage Power Display

Product Features1. Ultra thin mini design, easily embedded in various compact device spaces2. 0.5-inch high-definition OLED screen, clear visibility under strong light3. Can be used in 1-6S lithium battery systems, without voltage regulation, reverse connection without burning4. Intelligent percentage battery display, real-time monitoring of remaining battery life5. Digital display voltage+battery dual mode, with an accuracy of ± 0.1%Product SpecificationsThis voltmeter adopts a 0.5-inch OLED display screen and high-speed MCU, high-precision 12 bit ADC sampling, and stainless steel casing. The compact size with a thickness of only 3.8mm makes it practical and aesthetically pleasing overall. The header displays a voltage value and calculates the percentage of remaining battery power based on the battery voltage.Product SpecificationsWorking voltage: 4.5-30VMeasurement voltage: 0-30VWorking current: ≈ 10mAMeasurement accuracy: ± 0.1VSampling rate: ≈ 250 times/SThis meter head can measure 0-30V voltage in real time, but the percentage of electricity needs to be set to the corresponding string number, otherwise the percentage display will be relatively inaccurate.Method for setting the number of battery stringsShort circuit the number of strings with tweezers to set the solder pad and negative electrode for two seconds (similar to long pressing a button), and hold for about 3 seconds. The STD character on the right side of the screen starts flashing, indicating that it has entered the serial number setting mode. Afterwards, tap the short-circuit string number to set the solder pad and negative electrode, which can cycle between 1-6 strings. The number displayed in the box corresponds to the corresponding string. After stopping the operation for 5 seconds, the system automatically saves and exits the setting mode.Package containsVoltage and electricity meter * 1
