在(zai)儀器的(de)(de)(de)(de)使用中,應經(jing)常注意(yi)電(dian)(dian)(dian)源的(de)(de)(de)(de)變化,不能長期在(zai)過(guo)(guo)壓(ya)或欠壓(ya)下工作,根據資(zi)料介紹(shao),當儀器在(zai)過(guo)(guo)壓(ya)下工作會造成高(gao)頗發生器功(gong)率大(da)管(guan)燈絲過(guo)(guo)度的(de)(de)(de)(de)蒸發和老化,電(dian)(dian)(dian)子(zi)管(guan)的(de)(de)(de)(de)壽(shou)(shou)(shou)命將(jiang)會大(da)大(da)的(de)(de)(de)(de)縮短(是正常壽(shou)(shou)(shou)命的(de)(de)(de)(de)五分(fen)之(zhi)~一(yi)六分(fen)之(zhi)一(yi))。如果在(zai)欠壓(ya)下工作,電(dian)(dian)(dian)子(zi)管(guan)燈絲溫度過(guo)(guo)低,電(dian)(dian)(dian)子(zi)發射不好(hao),也容易造成電(dian)(dian)(dian)子(zi)發射材(cai)料過(guo)(guo)早老化,同(tong)樣也縮短電(dian)(dian)(dian)子(zi)管(guan)的(de)(de)(de)(de)壽(shou)(shou)(shou)命;儀器運行中供電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)的(de)(de)(de)(de)較(jiao)大(da)波動(dong)同(tong)樣也會造成高(gao)頻發生器輸出功(gong)率的(de)(de)(de)(de)不穩定(ding),對測定(ding)結果的(de)(de)(de)(de)好(hao)壞影(ying)響(xiang)極大(da),因此,應當注意(yi)供電(dian)(dian)(dian)電(dian)(dian)(dian)源的(de)(de)(de)(de)質量。
