#DC #600V #20A #Dual #Digital #Voltmeter #Ammeter #Volt #Amp #Tester #Gauge #Meter #Red+Green #LED Extreme working conditions: Min. supply voltage: + 3.5V Max. supply voltage: + 30V Working temperature: -10 ~ + 65℃ Operating Humidity: 10 ~ 80% (non-condensing) Working pressure: 80 ~ 106kPa Sunlight: no direct exposure Link information Power meter: Two line socket Thin - Black Line: Header supply Negative Thin - Red line: Header supply positive (Note: voltage between red and black lines can't exceed 30V) Test side: Three line socket COM: Test Common V +: Test positive voltage input A +: Test "positive" current input; check the drawing before install or it will burn. Because the header by co-design, which means the earth wire of test and power supply is interlinked,so only can be connected to between the negative power supply and the negative of the tested device (We recommend to link the yellow line and the black lines together, to prevent outside interference caused by digital ammeter flashing) Specifications: Material: Plastic Color: Black/White Voltage Measuring Range: 0-600V Voltage Resolution: 1V Impedance: >2M Current Measuring Range: 0.00-9.99-20.0A Current Resolution: 0.01A(Below 10A) 0.1A(Above 10A) Supply voltage (non-isolated meter): DC 3.5 ~ 30V (wide range) Note: The maximum input voltage can not exceed 30V, otherwise it will be burned Isolation meter (isolated power supply meter): DC8-18V Operating Current: <20mA Display: 0.39 "LED, voltage - red, Current - Green Measurement rate: ≥500mS / times Accuracy: 1% (± 1 word) Installation hole: 68x38 mm Size: 70x40x30mm Quantity: 1 Pc Note: 1.Transition: 1cm=10mm=0.39inch 2.Please allow 0-3cm error due to manual measurement. pls make sure you do not mind before you bid. 3.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Package includes: 1 x Digital Voltmeter Ammeter
