3 Pack 0.28 inch Digital Voltmeter Ammeter DC 100V 10A Amp Voltage Current Meter Tester 3 Bits Blue + Red Dual LED Display Panel with Connect Wires

Features

• Product Features Functions perfect set of voltage and current meter in one, measuring current power taken from the measurement line, do not need isolated power supply for separate power supply, easy to use. Compact size (48mm * 29mm * 22mm).
• The basic performance parameters of the voltage and current meter are as follows. Opening size 45mm*26mmopening directly into the panel); Overall dimensions: 48mm*29mm*21mm; Supply voltage : DC3.5-28V (thin red line positive pole thin black line negative pole); Weight 20g/only;
• Display Double 4 digits 0.28 inch LED digital tube; Display color Red+Red; Refresh speed: about 200ms/time; Voltmeter range: DC 0.0-99.9V (resolution 0.1V) the fourth bit for the symbol bit; Voltage measurement accuracy (0.5%+2); Ammeter range: DC 0-999.9mA-3.000A Automatic change of accuracy; Current measurement accuracy: (0.3% + 2 words);
• The digital tube above the head of the meter shows the measured voltage, three fixed display precision, the fourth symbol bit, display **. *U. Measuring range 0-99.9V, the minimum resolution is 100mV.The digital tube below the meter head shows the measured current, four-bit variable display precision, measuring range 0-3.000A, when the measured current is greater than 1A, the display precision is 1mA; when the measured current is less than 1A, the display precision is 0.1mA.
• Description of on-board wire functions: Thin red wire (VCC): power supply input positive (3.5-28V); Note: If the measurement signal is lower than 28V and the power supply is sufficient, it can be directly used as the power supply of the module (use the thin yellow wire and the thin red wire in parallel). Thin black wire (GND): power supply input negative (3.5-28V) and measurement signal common ground. Thin yellow wire (VIN): Positive measurement signal input (0-99.9V).
