計量(liang)(liang)是(shi)(shi)實現(xian)(xian)單位統一、量(liang)(liang)值準確(que)可靠(kao)的活動。或者(zhe)說是(shi)(shi)以實現(xian)(xian)單位統一、量(liang)(liang)值準確(que)可靠(kao)為(wei)目的的測(ce)量(liang)(liang)。它涉及整個(ge)測(ce)量(liang)(liang)領域(yu)，并按法律規定，對(dui)測(ce)量(liang)(liang)起著指導、監督(du)、保證作(zuo)用。新購(gou)買(mai)的儀器有長(chang)途運輸震動或長(chang)時間(jian)震動的經歷。儀器的放置也可能(neng)會改(gai)變儀器的測(ce)量(liang)(liang)精度(du)，所以為(wei)了(le)您(nin)的，我建議(yi)新購(gou)買(mai)的儀器，盡(jin)量(liang)(liang)先校準，再使(shi)用。計量(liang)(liang)檢(jian)測(ce)工(gong)作(zuo)是(shi)(shi)一項科學而嚴(yan)謹的工(gong)作(zuo)，從檢(jian)定、校準原始記錄(lu)(lu)到證書的出(chu)具(ju)，每一個(ge)環節(jie)都來(lai)不得半點馬(ma)虎(hu)。真實有據、完整無缺(que)、準確(que)可靠(kao)是(shi)(shi)對(dui)原始記錄(lu)(lu)基本的要求。
