DC 5V-38V Digital LCD Display Voltmeter Ammeter Multi-Function Volt Current Voltage Meter Tester Sound Light Alarm Indicator

Sensor Blocks1. Product Highlights The measurement circuit draws power from the power input port and does not require an additional power cord.LCD display, which can display voltage, current, power, discharge mAH, discharge time and operating temperature.Complete protection mechanism with various protections such as undervoltage protection, overvoltage protection, overcurrent protection, overpower protection, overtemperature protection, overtime protection and over capacity.Overcharge and overdischarge control of the battery can be achieved by setting appropriate undervoltage protection and overvoltage protection thresholds.Timed and quantified battery charging and discharging can be achieved by setting appropriate timeout protection and over capacity protection thresholds.2. Product parameters3. Product Description3.1 Product Features1, LCD displayIn normal mode, the LCD displays the input voltage and operating temperature on the upside; the downlink shows the real-time current, power, capacity, and discharge time.In protected mode, the LCD displays the protection code.In the setting mode, the LCD displays various setting parameter codes and parameter thresholds.2, sound and light alarmWhen the output of the voltage ammeter is turned on, the RUN indicator is always on and the buzzer is not ringing; when it is off, the RUN indicator is off and the buzzer is not ringing. After entering the protection mode, the buzzer will drop the alarm and the RUN indicator will flash.3, charge and discharge capacity and time automatic statistics, as long as the output is turned on (RUN indicator is always on) to start statistics, turn off the output (RUN indicator is not lit), stop statistics, power-down statistics are automatically cleared, in the display capacity and time When the interface is pressed, long press the button - the corresponding data can be cleared. Please clear the statistics before st
