XL4005型數字式交流/直流峰值電壓表

XL4005數字式交流(liu)/直流(liu)峰(feng)(feng)值(zhi)(zhi)(zhi)電(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)是為直流(liu)高壓(ya)(ya)試驗、交流(liu)/工頻(pin)高壓(ya)(ya)試驗而設計的(de)測(ce)量(liang)儀器。 該(gai)儀器直流(liu)可以(yi)測(ce)量(liang)正(zheng)(zheng)、負極性直流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)(zhi)(zhi)，紋波電(dian)(dian)(dian)(dian)壓(ya)(ya)、紋波系數。交流(liu)可以(yi)測(ce)量(liang)交流(liu)正(zheng)(zheng)弦波（工頻(pin)）及交流(liu)非正(zheng)(zheng)弦波的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)峰(feng)(feng)值(zhi)(zhi)(zhi)（正(zheng)(zheng)峰(feng)(feng)值(zhi)(zhi)(zhi)、負峰(feng)(feng)值(zhi)(zhi)(zhi)、峰(feng)(feng)峰(feng)(feng)值(zhi)(zhi)(zhi)），峰(feng)(feng)值(zhi)(zhi)(zhi)/√2（真有效(xiao)值(zhi)(zhi)(zhi)），周期均方(fang)根值(zhi)(zhi)(zhi)，波形(xing)(xing)畸變(bian)率及高次(ci)諧波。并能(neng)顯示和保存電(dian)(dian)(dian)(dian)壓(ya)(ya)波形(xing)(xing)、升壓(ya)(ya)曲線(xian)。 為防止(zhi)電(dian)(dian)(dian)(dian)磁場及電(dian)(dian)(dian)(dian)源的(de)干擾，在電(dian)(dian)(dian)(dian)路中采用了(le)一系列抗干擾措施，故對各種(zhong)干
