Joint measurement _ Open and close Hall current transmitter _ Aperture

The current transmitter can directly convert the AC or DC current of the tested main circuit into a DC (4~20) mA output in linear proportion (converted to DC (1~5) V through a 250 Ω resistor or DC (2~10) V through a 500 Ω resistor) constant current loop standard signal, which is continuously transmitted to the receiving device (computer or display instrument).
