1、在使用前應(yīng)檢查電源電壓和計(jì)數(shù)繼電器額定工作電壓是否相符，允許電源電壓波動(dòng)范圍額定值的85%～110%，直流電壓峰值紋波系數(shù)不大于5%，并注意其極性。 </p> <p> 2、計(jì)數(shù)器計(jì)數(shù)信號(hào)輸入和信號(hào)線選擇可參考本文第5部分所述，計(jì)數(shù)信號(hào)應(yīng)在計(jì)數(shù)器接通電源或復(fù)位50ms后再輸入計(jì)數(shù)信號(hào)，否則可能產(chǎn)生計(jì)數(shù)不穩(wěn)定現(xiàn)象，外接的復(fù)位信號(hào)持續(xù)時(shí)間應(yīng)大于50ms。 </p> <p> 3、在計(jì)數(shù)過程中，不宜撥動(dòng)計(jì)數(shù)器的指輪開關(guān)，若要重新置數(shù)，應(yīng)先使計(jì)數(shù)器復(fù)位。 </p> <p> 4、計(jì)數(shù)器的工作電源應(yīng)盡量避免與電動(dòng)機(jī)、電磁鐵等較大的感性負(fù)載共用一根電源線。 </p> <p> 5、計(jì)數(shù)繼電器控制觸頭應(yīng)在不超出其容量范圍內(nèi)使用。 </p> <p> 6、計(jì)數(shù)器應(yīng)盡量避免在有明顯搖動(dòng)或者經(jīng)常受到振動(dòng)的場(chǎng)合使用。 </p> <p> 7、應(yīng)避免在遭受雨雪侵襲，油及陽(yáng)光直射的場(chǎng)合中使用。 </p><p> 狹義的計(jì)數(shù)器是指一些常用計(jì)時(shí)器，例如體育比賽中測(cè)試時(shí)間的計(jì)時(shí)器等，但本詞條所要介紹的并不是這種計(jì)時(shí)器，要介紹的是應(yīng)用更為寬泛的時(shí)序邏輯電路中的計(jì)數(shù)器。在數(shù)字電子技術(shù)中應(yīng)用的較多的時(shí)序邏輯電路。計(jì)數(shù)器不僅能用于對(duì)時(shí)鐘脈沖計(jì)數(shù)，還可以用于分頻、定時(shí)、產(chǎn)生節(jié)拍脈沖和脈沖序列以及進(jìn)行數(shù)字運(yùn)算等。但是并無(wú)法顯示計(jì)算結(jié)果，一般都是要通過外接LCD或LED屏才能顯示。光亞的呼吸機(jī)**計(jì)數(shù)器質(zhì)量好嗎？</p>
