ARCELI Digital Multimeter, 00203 Model, Dual LED Display Voltmeter, DC 4.5-30V Ammeter 0-50A, Voltage Current Meter, Volt Amp Panel Monitor for Auto Car Motor

• Three-digit 0.28 inch LED dual display, red display for voltage, blue for current, requires an additional 50A shunt for current measurement.
• Measuring range is DC 4.5-30V / 0-50A, can be calibrated, commonly used for automotive, camper, solar system, electric bicycle, etc.
• The decimal point would automatically move according to the different voltage tested.
• Receives power from the tested circuit and requires no additional power supply.
• With reverse connection protection to avoid burnout when connected in reverse.

Features: Double LED: red voltage, blue current, display voltage current at the same time. This panel gauge is a common ground design. It means that the ground cable and ground of the power supply are grounded. Power supply DC 4.5-30V. With reverse polarity protection, but the maximum power supply cannot exceed 30VDC. Specific: Power supply (measuring voltage): DC 4.5-30V. Voltage: <10 V, resolution: 0.01 V. Voltage > = 10 V, Resolution: 0.1 V Measure current: 0-50A forward current (requires an additional 50A shunt for current measurement). Current Resolution: 0.1A Operating current: <20 mA. Display: 0.28 inch LED dual colour (red and blue). Dimensions: 48 x 29 x 21 mm. Cutting size: 45 x 26 mm Measuring rate: ≥ 500 mS/times. Accuracy: 1% (± 1 digit). Operating temperature: -10 °C ~ + 65 °C. Operating humidity: 10 ~ 80% (non-condensing). Working pressure: 80 ~ 106 kPa. Wire connection: COM: black wire, power supply, voltage measurement - PW +: red cable, power supply +, measure voltage + IN+, yellow wire, measure current input. If you only use the voltmeter function, please connect the yellow cable and black cable together to avoid interference Please check the description picture for more details. Package includes: 1 x amp voltmeter 2-in-1
