使高电压通道远离敏感的小电流通道，并使用良好屏蔽的开关，可将这种误差降至最低。

This can be minimized by locating the high voltage channels away from the sensitive low current channels and by using well-shielded switches.

硬件措施主要包括接地、屏蔽、滤波和隔离等，另外还需注意采取措施提高微机I/O通道的抗干扰能力；

Techniques based on hardware mainly include grounding, shielding, filtering and isolation. Measures should be taken to improve the anti-interference ability of I/O channels in PC as well.
