volt-ohm-meter
基本解釋
- 伏歐表
英漢例句
- DVOM digital volt ohm meter
數(shù)字電壓電阻表 - Analyzing the whole measuring process of the Ohm meter,an estimate formula for the resistance uncertainty is derived.
從分析歐姆表測(cè)量的全過程出發(fā),導(dǎo)出了電阻測(cè)量不確定度的估計(jì)公式. - Micro ohm meter has been used to measure the contact resistance commonly at present.
目前最常用的接觸電阻測(cè)試儀器是微歐儀,這些儀器普遍採用大電流恒流源,因此躰積和重量都很大。 - Analyzing the whole measuring process of the Ohm meter, an estimate formula for the resistance uncertainty is derived.
儅微安表改裝爲(wèi)歐姆表後 ,儅電池電壓變化時(shí) ,改裝表測(cè)量值會(huì)産生很大誤差。 - DVM is not accurate in measuring resistance below 20 ohm due to the lead resistance, unless it is a 4 wired ohm meter.
數(shù)字式電壓表在測(cè)量低於20歐姆的電阻時(shí),會(huì)因爲(wèi)引腳的電阻而使測(cè)量不準(zhǔn)確.;除非它是一個(gè)四線歐姆表
