Basic description:

HGIDA4 data collector, also known as: current voltage converter, current amplifier. It is used to measure weak current signal and can also be converted into voltage signal. It can be measured directly with multimeter, oscilloscope and other voltage acquisition equipment. It can also transmit digital signal through serial port and be identified and processed by computer. It is especially suitable for developing optoelectronic instruments and integrated optoelectronic instruments and equipment systems, saving time and labor cost for small and medium-sized enterprises and individual entrepreneurs, or as a common weak current signal measurement tool.

Application Description:

Type B USB bus port is a power supply digital signal output port. When it is used as digital signal output, USB to serial port drive is required. It shall be controlled according to the communication protocol provided later. The BNC port near the USB port is the voltage output end, the BNC port on the other side is the current input end, and the small hole on the top is used for gain adjustment. Multi turn adjustable resistance is used to adjust the amplification gain.

Note: the input impedance of the current input port is very small. Do not connect the voltage signal, otherwise the equipment will be damaged.
