LED Digital Voltage Meter DC 2V Power Supply DC 5V 4 1/2 Mini DC Voltmeter Car Blue Color Digits 4.5 Volt Panel Meter Tester(White Cover-Red)

AmmetersLED Digital Voltage Meter DC 2V Power Supply DC 5V 4 1/2 Mini DC Voltmeter Car Blue Color Digits 4.5 Volt Panel Meter Tester Attention: 1.The negative of power supply and the testing side are connected,so it is recommended to use a separate power supply(ie: independent power supply). 2.If you select "Power supply DC5V",the working voltage is "5V±0.5V",or it will be burnt. Technical Parameters: Power supply: DC5V(5V±0.5V) <;100mA Test voltage: DC2V Dimension:79*43*25 mm Mounting hole:76*39.5mm Display mode: 0.4 "LED Measurement accuracy: 0.1% (± 2 digits) Measurement rate: 2 times/S This meter can test positive and negative value. Power supply reverse protection. The crystal of the meter is quartz crystal with high precision and high stability. The LED digital tube display part, with all the limited current resistance, will be not appeared "the bright and dark inconsistency". Package Include: 1 piece* LED Digital DC Voltage Meter Working conditions: Working humidity: 10 ~ 80% (no condensation)Working pressure: 80 ~ 106kPaSun exposure: no direct exposure
