0.56" DC 100V 50A Red+Red Dual LED Display Mini Digital Voltmeter Ammeter Panel Amp Volt Voltage Cur

Description: ? Operating voltage:DC 4 ~ 30V Measure voltage: DC 0 ~ 100V Minimum resolution(V): 0.1V Measure current :50A (require external shunt) Minimum resolution(A): 0.1A Operating current: <20mA Display: three 0.28 LED digital tube Display color: Red and Red Refresh rate: about 300mS / times Measure accuracy: 1% (&pm; 1 digit) Operating temperature: -10 to 65?ﾣ c Operating Humidity: 10 to 80% (non-condensing) Working pressure: 80 to 106 kPa Applications:Suitable for automotive/electric cars/motorcycles battery monitoring or other products voltage current measurement ? 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+ ? Notice: ? The voltage between the thin red and thin black lines must be within DC 4-30V 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 It is unsuitable to use this meter to test current less than 10A . ? Package included ? 1 x Digital Voltmeter Ammeter Meter 1 x Current Shunt 1 x Cable
