0.28" Volt Meter, DC 0-100V 10A Digital Voltmeter Ammeter Dual 3 Bits LED Display with Connect Wires Mini Ammeter Voltmeter for Electronic Circuit Experiments Cars RV Solar Energy (3Pack)

Working Attributes: Measurement Range Voltage is 0~100V, Current 0~10A. The working voltage of the meter itself is DC 4 - 30V. ( The maximum input voltage can not exceed 30V. Otherwise, the meter will be burned) Refresh speed is about 300ms / time

Dual Display Design: Adopting a 0.28" red and blue LED display screen, it can simultaneously display current and voltage, making it convenient for users to monitor the current and voltage status in the circuit at the same time

High Precision& Stability: Measure accuracy: 1% (± 1 digit). Ensure the accuracy of each measurement. Suitable for situations where high measurement accuracy is required. Using high-quality electronic components and stable circuit design to ensure long-term reliability

Wide Applicability: suitable for various occasions such as home maintenance, hydropower engineering, professional engineering, etc., with high practicality

Attention: The header uses original imported chips, which undergo very strict testing and calibration before leaving the factory to ensure no quality problems occur. 99.99% of cases where the current displays 0 are due to incorrect wiring. Please be patient and carefully check the wiring
