Onboard Wire Instructions:

Thin Red Wire (VCC): positive pole of power supply input (3.5-30V)
(Note: if the measuring signal is less than 30V and the power is adequate, can be the power supply of module)
Thin Black Wire (GND): negative pole of power supply input (3.5-30V, common ground with measuring signal)
Green Wire (VIN): positive pole of measuring signal input (0-100V)
Thick Red Wire (I+): positive pole of current input (series connect on the power supply cathode)
Thick Black Wire (I-): negative pole of current input (series connect on the power supply cathode)
