DVM is not accurate in measuring resistance below 20 ohm due to the lead resistance, unless it is a 4 wired ohm meter.
数字式电压表在测量低于20欧姆的电阻时﹐会因为引脚的电阻而使测量不准确。除非它是一个四线欧姆表。
The occurrence of the flying wave can lead to the error in shape control by shape meter using laser triangle method, but the error can be decreased or eliminated by laser capture method.
飘波的出现会导致用三角法测量板形时出现误差，而新型截光法板形仪可减轻或消除此误差。
