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