Highlights:
The customer purchased the 10mQ version, which can measure 6A DC current. Now the sampling resistance is changed to 2mQ. First, the instruction AT+R+2 is input, then AT+MAXC+40 is input. At this time, the module is changed to 2mQ version which can measure 30A DC current. What we need to know is that in theory, the smaller the sampling resistance, the wider the measurement range and the lower the accuracy. But compared with other products, it also belongs to high-precision detection.
