Note:
1. Sampling Rate: This parameter refers to the acquisition speed of the ADC chip.
2. In both ends of the Short-circuit channel, the current range has an error of 0.01~0.02mA, and the voltage range has a 0.001mV error, which is a normal phenomenon.
3. Data Communication Rate: This parameter refers to the communication speed between the MCU controller and the host computer.
