style="font-size:16px;color:#E53333;"><strong>1、選擇自動化程度高的儀器</strong></span> </p> <p> <span style="font-size:16px;">首先盡量選擇能自動加壓的校驗儀器，減少人工在現(xiàn)場升降壓過程；其次選擇具有“任務(wù)管理”、數(shù)據(jù)存儲功能的校準(zhǔn)儀器，任務(wù)管理即可以實現(xiàn)在辦公室將檢定任務(wù)數(shù)據(jù)錄入校驗儀器中，省去紙質(zhì)記錄的麻煩，紙質(zhì)記錄容易出錯，后續(xù)調(diào)用、溯源比較困難。</span> </p> <p> <span style="font-size:16px;color:#E53333;"><strong>2、選擇可便攜的儀器</strong></span> </p> <p> <span style="font-size:16px;">到工業(yè)現(xiàn)場開展校準(zhǔn)工作，攜帶的校準(zhǔn)儀器不宜過重，方便攜帶，可以自供電尤佳。</span> </p>
