Therefore, it's best to use the lowest possible voltage source range in order to minimize error.
所以，为了尽量降低误差，最好使用尽可能低的电压源量程。
It use special chip to realize full-range and equal observations for different voltage rate, without additional insulation faults for high input impedance .
本装置采用专用芯片，实现多种电压等级全范围等精度测量，同时输入阻抗高，不影响原车的绝缘状况；
