一、尋線儀的電池是幾號

尋線儀通(tong)常使(shi)(shi)用(yong)的(de)電(dian)(dian)池(chi)(chi)型號(hao)包括AA號(hao)和AAA號(hao)干電(dian)(dian)池(chi)(chi)，但(dan)也有(you)(you)一些尋線(xian)儀可能(neng)會使(shi)(shi)用(yong)CR2032鋰電(dian)(dian)池(chi)(chi)或9V電(dian)(dian)池(chi)(chi)。另外，雖尋線(xian)儀也有(you)(you)可能(neng)使(shi)(shi)用(yong)5號(hao)電(dian)(dian)池(chi)(chi)，但(dan)這(zhe)并不是常見的(de)規格，因此更(geng)可能(neng)是個別(bie)情況下的(de)例(li)外。通(tong)常情況下，尋線(xian)儀使(shi)(shi)用(yong)的(de)是AA號(hao)或AAA號(hao)電(dian)(dian)池(chi)(chi)。

二、尋線儀什么情況下要更換電池

尋線儀通常使(shi)用(yong)(yong)AA電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)或9V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)供電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)續(xu)航(hang)時(shi)間會受到使(shi)用(yong)(yong)環(huan)境和(he)頻率的(de)影響。在(zai)尋(xun)線(xian)(xian)儀使(shi)用(yong)(yong)過程中，如果出現檢測不到線(xian)(xian)路或電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)量不足(zu)的(de)情況，就(jiu)需要(yao)更(geng)(geng)換電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)了。其中，使(shi)用(yong)(yong)AA電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)尋(xun)線(xian)(xian)儀在(zai)電(dian)(dian)(dian)(dian)(dian)壓下降到1.5V以下時(shi)，就(jiu)需要(yao)更(geng)(geng)換新(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)了；而(er)使(shi)用(yong)(yong)9V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)尋(xun)線(xian)(xian)儀，可以繼(ji)續(xu)使(shi)用(yong)(yong)直至電(dian)(dian)(dian)(dian)(dian)壓下降到7V以下時(shi)，再更(geng)(geng)換新(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)。更(geng)(geng)換電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)時(shi)需要(yao)先(xian)取(qu)出原電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)，然后按照正(zheng)負極(ji)對應的(de)位(wei)置，安裝新(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)即可。

三、尋線儀電池電量怎么檢查

為了方(fang)便(bian)在使用(yong)尋線儀時能及時發現(xian)電(dian)池電(dian)量(liang)不(bu)足(zu)的情況，可以通(tong)過(guo)以下方(fang)法(fa)進行電(dian)量(liang)檢(jian)查：

1、使用(yong)萬(wan)用(yong)表進行(xing)電壓(ya)測試，以確認(ren)電池(chi)是否需要更換；

2、在尋線儀面板上，一(yi)般會設置一(yi)個電量指示(shi)(shi)燈或數(shu)字(zi)提示(shi)(shi)，可以通過這些指示(shi)(shi)器來判斷(duan)電池是(shi)否需要更(geng)換；

3、尋線儀本身(shen)會具備報(bao)警功能，當電池即將耗(hao)盡時，會發出聲(sheng)音(yin)或者閃爍(shuo)提(ti)示，以提(ti)醒使用者更換電池。
