style="text-indent:25px">噪聲測定儀的測量方法及注意事項(xiàng):測量方法1.使用前準(zhǔn)備裝上電池，將開關(guān)置于“電池檢查”位置，30秒鐘后指示燈亮，指針應(yīng)在紅線范圍內(nèi)，否則表示電壓不足，應(yīng)更換新電池。將開關(guān)放置在“快”或“慢”檔的位置（根據(jù)需要而定），此時(shí)指針應(yīng)回到－∞處。2.校正用活塞發(fā)生器校正。將計(jì)權(quán)網(wǎng)絡(luò)開關(guān)置于線性位置，順時(shí)針轉(zhuǎn)動輸出衰減器（透明旋鈕）轉(zhuǎn)到底，使旋鈕上的兩條紅線對準(zhǔn)面板上的紅線，將輸入衰減器（黑色旋鈕）上的l20dB刻度對準(zhǔn)紅線并在透明輸出旋鈕紅線之間。將活塞發(fā)生器套在電容傳聲器上，打開活塞發(fā)生器電源開關(guān)，活塞發(fā)生器即發(fā)出l24±0.2dB聲壓級的聲音。調(diào)節(jié)微調(diào)電位器，使指針指示出相應(yīng)的聲壓級讀數(shù)。如無活塞發(fā)生器，用儀器內(nèi)部電器校正信號校正。環(huán)境噪聲測量時(shí)，須注意使用之前應(yīng)使用活塞發(fā)聲器或聲級校準(zhǔn)器對聲級計(jì)進(jìn)行校準(zhǔn)。</p><div
