2、變壓器綜合測(cè)試儀由zui初的數(shù)據(jù)采集到zui后顯示、打印，保存給用戶，全部集成在一起，而且全程實(shí)現(xiàn)完全自動(dòng)化，在其測(cè)試得出的數(shù)據(jù)可以相應(yīng)同步到表格里，避免了人工轉(zhuǎn)抄的麻煩; 3、專業(yè)的變壓器綜合測(cè)試儀帶液晶背光顯示屏，同時(shí)顯示三相電壓電流等十八個(gè)參量;在其數(shù)字儀表取其代指針儀表。每次更新的數(shù)據(jù)做到同步鎖定在屏幕上，不但解決了因視差、換算、計(jì)算等諸多因素造成的誤差，而且徹底解決了操作人員同時(shí)因讀和看多塊表計(jì)，又要記錄多組數(shù)據(jù)的困難，保證試驗(yàn)數(shù)據(jù)的準(zhǔn)確可靠。上海試驗(yàn)變壓器廠</p></p><br
