Wiring Instruction:
RED(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 meter. black wire and yellow wire are contacted together to use)
Black(GND): Power input- , Measurement signal- (3.5-28V)
Yellow(VIN): Measurement signal+ (0-33.00V)
RED(I+): Current input+ (must be connected in series between Power Supply Negative and Load Negative)
Black(I-): Current input- (must connected in series between Power Supply Negative and Load Negative)
