volt-ohm-meter

基本解释

DVOM digital volt ohm meter
数字电压电阻表
Analyzing the whole measuring process of the Ohm meter,an estimate formula for the resistance uncertainty is derived.
从分析欧姆表测量的全过程出发，导出了电阻测量不确定度的估计公式.
Micro ohm meter has been used to measure the contact resistance commonly at present.
目前最常用的接触电阻测试仪器是微欧仪，这些仪器普遍采用大电流恒流源，因此体积和重量都很大。
Analyzing the whole measuring process of the Ohm meter, an estimate formula for the resistance uncertainty is derived.
当微安表改装为欧姆表后 ,当电池电压变化时 ,改装表测量值会产生很大误差。
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
