一、尋線儀的電池是幾號

尋線儀通常使用的電(dian)池(chi)型號(hao)(hao)包括AA號(hao)(hao)和AAA號(hao)(hao)干(gan)電(dian)池(chi)，但(dan)也有(you)(you)一些尋線儀(yi)可(ke)能(neng)會使用CR2032鋰電(dian)池(chi)或9V電(dian)池(chi)。另外(wai)，雖尋線儀(yi)也有(you)(you)可(ke)能(neng)使用5號(hao)(hao)電(dian)池(chi)，但(dan)這并(bing)不(bu)是(shi)常見的規格，因(yin)此更可(ke)能(neng)是(shi)個別情況(kuang)下(xia)(xia)的例外(wai)。通常情況(kuang)下(xia)(xia)，尋線儀(yi)使用的是(shi)AA號(hao)(hao)或AAA號(hao)(hao)電(dian)池(chi)。

二、尋線儀什么情況下要更換電池

尋線儀通常(chang)使(shi)(shi)用(yong)AA電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)或(huo)(huo)9V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)續航時(shi)間(jian)會受到使(shi)(shi)用(yong)環境和(he)頻(pin)率的(de)(de)影響。在尋(xun)線(xian)儀(yi)使(shi)(shi)用(yong)過程中，如(ru)果出(chu)現檢測(ce)不到線(xian)路或(huo)(huo)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)量(liang)不足的(de)(de)情況(kuang)，就需要(yao)更(geng)換(huan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)了。其中，使(shi)(shi)用(yong)AA電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)尋(xun)線(xian)儀(yi)在電(dian)(dian)(dian)(dian)(dian)壓下降(jiang)到1.5V以(yi)下時(shi)，就需要(yao)更(geng)換(huan)新(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)了；而使(shi)(shi)用(yong)9V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)尋(xun)線(xian)儀(yi)，可(ke)以(yi)繼續使(shi)(shi)用(yong)直至電(dian)(dian)(dian)(dian)(dian)壓下降(jiang)到7V以(yi)下時(shi)，再更(geng)換(huan)新(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。更(geng)換(huan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)時(shi)需要(yao)先取出(chu)原電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，然(ran)后按(an)照(zhao)正負極對應的(de)(de)位置，安裝新(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)即可(ke)。

三、尋線儀電池電量怎么檢查

為(wei)了方便在(zai)使用尋線儀時能及(ji)時發現電(dian)池(chi)電(dian)量不足的情況，可以(yi)通過以(yi)下方法進行(xing)電(dian)量檢查：

1、使用萬(wan)用表進行(xing)電壓測試，以(yi)確認電池是否(fou)需要(yao)更換；

2、在尋線儀面板(ban)上，一(yi)般(ban)會設置一(yi)個電量(liang)指(zhi)示燈或(huo)數(shu)字提示，可以(yi)通過這些(xie)指(zhi)示器來判斷(duan)電池是(shi)否需要更換；

3、尋線儀本身(shen)會具備報警功能，當電(dian)池即將耗盡時(shi)，會發出(chu)聲音(yin)或者閃爍提(ti)示，以提(ti)醒使用(yong)者更(geng)換電(dian)池。
