Display description:

  • The above digital tube display voltage; there are three fixed display precision. The fourth bit is  sign bit, displaying 'U'. The measurement range is 0.0-99.9V; the minimum resolution is 100mV
  • The below digital tube display current; there are four fixed display precision; the measurement range is 0-999.9mA-3.000A. When the measuring current is below 1A, it display ***.*mA, the resolution is 0.1mA; When the measuring current is higher than 1A, it display *.***A, the resolution is 1mA

 

Instruction of wiring

  Red thin wire (VCC): Power input+ 3.5-28V (NOTE: If the measuring signal is lower than 28V and have abundant power supply, it can be used as power supply for the module [black wire and yellow wire are contacted together to use])

  Black thin wire(GND): Power input- Measurement signal - 3.5-28V

  Yellow thin wire (VIN): Measurement signal+ (0-99.9V)

  Red thick wire (I+): Current input+ (connect with the load negative)

  Black thin wire(I-): Current input- (in series in power supply negative)

Wiring instruction:

  Voltage current meter with isolated power supply

  Voltage current meter in the measurement system for power supply

  • System supply power-1

 

  • System supply power-2
