Digital Voltmeter & Ammeter 10A

DC 0-100V 10A Dual Red LED Digital Voltmeter Panel with Ammeter DisplayProduct Features:    Can measure voltage and current at the same time.    Brand new and high quality.    Display color: Red & Blue LED(dual colordisplay).    Display: 0.28 LED digital.    Operating voltage (Input Voltage): DC 4.5 ~ 30V.    Measure voltage: DC 0 ~ 100V.    Minimum resolution (V): 0.1V.    Refresh rate: =500ms / times.    Measure accuracy: 1% (± 1 digit).    Minimum resolution (A): 0.01A.    Operating Current: <20mA.    Measure current: 5A (direct measurement, built-in shunt).    Operating temperature: -10 to 65°c.    Operating Humidity: 10 to 80% (non-condensing).    Mounting cutout: 45.5mm x 26.5mm.    Size: 48mm x 29mm x 21mm.    Operating voltage:DC 4.5 ~ 30V    Measure voltage: DC 0 ~ 100V    Minimum resolution(V): 0.1V Wiring:    Black line (thin): vacant or buck circuit (module) negative    Red line (thin): power supply+    Black line (thick): COM, common measuring    Red line (thick): PW+, measuring terminal voltage input positive    Yellow line (thick): IN+, current input+    (Please refer to the wiring diagrams for more details)NOTES: (Two types of this Voltmeter-ammeter. Check the photo above ):    1. The voltage between the thin red and thin black lines must be within DC 4.5-30V    2. The ammeter can only be connected to the negative of the device under test    3. 10A below ammeter (include 10A), built-in shunt, does not require external shunt    4. Exceeds 5A, long-term full load working continuously, it is recommended that the measurement side of the leads are directly soldered to the socket    5. When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits    6. 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 flashingPackage Included:    1 x DC 0-100V Voltmeter Ammeter
