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