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