Stayhome 1pcs Digital Multimeter Dual LED Display Voltmeter DC 4.5V to 30V Ammeter 0 to 100A Voltage Current Meter Volt Amp Panel Monitor Red

Description: 3 digits 0.28 " LED dual display, red display for voltage, red for current, needs an extra 100A shunt for measuring current. Measuring range is DC 4.5-30V/0-100A, can be calibrated;commonly used for automotive, camper,solar system, electrical bike etc. Decimal point would move automatically in accordance with different tested voltage. Gains power from tested circuit and requires no extra power supply. With reversed-connection protection to avoid burning when connected reversely. Features: Dual LED: Red voltage, red current, Display Voltage Current at same time This panel meter is common ground design, it means that the (measure ground wire) and (power supply ground) is common ground. Power Supply DC 4.5-30V. With reverse polarity protection, but the max power supply can not exceed 30VDC. Specification: Power Supply (Measure Voltage): DC 4.5-30V voltage < 10V, resolution: 0.01V voltage >= 10V, resolution: 0.1V Measure Current: 0-100A forward current (need an extra 100A shunt for measuring current) Current Resolution: 0.1A Operating Current: <20mA Display: 0.28 "LED Dual-color (red and red) Dimensions: 48 x 29 x 21 mm Cutting Size: 45 x 26 mm Measurement rate: ? 500mS / times Accuracy: 1% (± 1 digit) Operating Temperature: -10°c ~ +65°c Operating Humidity: 10 ~ 80% (non-condensing) Working pressure: 80 ~ 106kPa
