数字式电压表通常有10兆欧的输入阻抗。当测量高阻抗电路时﹐可能会有影响。
DVM usually got an input impedance of 10 Mohm. There may be loading effect when measuring high impedance circuit.
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。
DVM is not accurate in measuring resistance below 20 ohm due to the lead resistance, unless it is a 4 wired ohm meter.
