SMAKN Dc Volt Amp Meter 2in1 Digital Amperemeter Voltmeter LED Tester Red 0-100v/2a Car Battery Monitor
Feature: Operating voltage:DC 4.5 - 30V Measure voltage: DC 0 - 100V Minimum resolution(V): 0.1V Measure current :2A Minimum resolution(A): 0.1A Operating current: <20mA; Display: three 0.28" LED digital tube Display color: Red a Dimensions: 48 x 29 x 21mm Mounting cutout: 45.5 x 26.5mm Refresh rate: about 500mS / times Measure accuracy: 1% (± 1 digit) Operating temperature: -10 to 65° c Operating Humidity: 10 to 80% (non-condensing) Working pressure: 80 to 106 kPa Applications:Suitable for automotive/electric car/motorcycles battery monitor or other products voltage current measure Wiring: Black line (thin): vacant or buck circuit (module) negative Red line (thin): power supply+ Black line (thick): COM, common measure Red line (thick): PW+, measure terminal voltage input positive Yellow line (thick): IN+, current input+ (Please refer to the wiring diagrams for more details) Notice: The voltage between the thin red and thin black lines must be within DC 4.5-30V The ammeter can only be connected to the negative of the device under test Exceeds 5A, long-term full load working continuously, it is recommended that the measurement side of the leads are directly soldered to the socket When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits If just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing Package include: 1x Digital Volt Amp Meter
