任何(he)設備在使用(yong)前都需要對其進行(xing)檢查(cha)，電纜故(gu)障測(ce)試儀(yi)也不例(li)外，今(jin)天小編就(jiu)為大(da)家介紹(shao)一(yi)下(xia)使用(yong)電纜故(gu)障測(ce)試儀(yi)前對其接收機的(de)檢查(cha)事項，想(xiang)要了解的(de)朋友一(yi)起跟隨小編的(de)介紹(shao)看(kan)一(yi)下(xia)吧。
1、電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)量檢查：按下電(dian)(dian)(dian)(dian)(dian)(dian)源鍵檢查電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)量。如果電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)量充足，則顯(xian)示器中(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)符(fu)號(hao)五(wu)個實線條全部顯(xian)示，當電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)符(fu)號(hao)只有一個實線點亮(liang)時，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)符(fu)號(hao)閃爍，表示電(dian)(dian)(dian)(dian)(dian)(dian)量不足，需充足電(dian)(dian)(dian)(dian)(dian)(dian)后使(shi)用。
2、無(wu)源工(gong)作方(fang)式檢查(cha)：按(an)下頻(pin)率鍵選擇50Hz的工(gong)作頻(pin)率，調節靈(ling)敏(min)度，從1米以外把SL-480接收(shou)機(ji)指(zhi)(zhi)向日光(guang)燈(deng)，打開(kai)日光(guang)燈(deng)應該聽到很(hen)(hen)強的信號音，顯(xian)示器會(hui)有很(hen)(hen)強的顯(xian)示指(zhi)(zhi)示。
3、有源工作方(fang)式檢查(cha)：選擇一個沒有干(gan)擾的(de)地方(fang)，把(ba)發射(she)機(ji)(ji)(ji)(ji)按正常的(de)方(fang)位放在地面上，打開發射(she)機(ji)(ji)(ji)(ji)，調節好發射(she)頻率。然后把(ba)把(ba)接(jie)收機(ji)(ji)(ji)(ji)（離(li)發射(she)機(ji)(ji)(ji)(ji)5米左右）寬面對準發射(she)機(ji)(ji)(ji)(ji)，并保持與發射(she)機(ji)(ji)(ji)(ji)相(xiang)同(tong)的(de)頻率，把(ba)靈(ling)敏(min)度調節到(dao)足夠(gou)大時接(jie)收機(ji)(ji)(ji)(ji)應該有信號響應。
