一、尋線儀的電池是幾號

尋線儀通常使(shi)(shi)用(yong)(yong)的電(dian)池(chi)(chi)型(xing)號(hao)包括AA號(hao)和AAA號(hao)干電(dian)池(chi)(chi)，但(dan)也有一些尋(xun)線(xian)儀(yi)(yi)(yi)可(ke)能會使(shi)(shi)用(yong)(yong)CR2032鋰電(dian)池(chi)(chi)或(huo)9V電(dian)池(chi)(chi)。另外，雖尋(xun)線(xian)儀(yi)(yi)(yi)也有可(ke)能使(shi)(shi)用(yong)(yong)5號(hao)電(dian)池(chi)(chi)，但(dan)這并不是常見的規格(ge)，因此更可(ke)能是個(ge)別情(qing)況(kuang)下的例外。通常情(qing)況(kuang)下，尋(xun)線(xian)儀(yi)(yi)(yi)使(shi)(shi)用(yong)(yong)的是AA號(hao)或(huo)AAA號(hao)電(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)(shi)用(yong)AA電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)或9V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)供(gong)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)續(xu)航時(shi)間會受到使(shi)(shi)用(yong)環(huan)境和頻率的(de)影(ying)響(xiang)。在尋(xun)線(xian)(xian)(xian)儀使(shi)(shi)用(yong)過程中(zhong)，如果出現(xian)檢測(ce)不到線(xian)(xian)(xian)路(lu)或電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)量不足的(de)情況，就需要(yao)更(geng)(geng)換(huan)(huan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)了。其中(zhong)，使(shi)(shi)用(yong)AA電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)尋(xun)線(xian)(xian)(xian)儀在電(dian)(dian)(dian)(dian)(dian)壓(ya)下(xia)降到1.5V以下(xia)時(shi)，就需要(yao)更(geng)(geng)換(huan)(huan)新電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)了；而使(shi)(shi)用(yong)9V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)尋(xun)線(xian)(xian)(xian)儀，可(ke)以繼續(xu)使(shi)(shi)用(yong)直至電(dian)(dian)(dian)(dian)(dian)壓(ya)下(xia)降到7V以下(xia)時(shi)，再更(geng)(geng)換(huan)(huan)新電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。更(geng)(geng)換(huan)(huan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)時(shi)需要(yao)先取出原電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，然后按照(zhao)正負極對應的(de)位置，安(an)裝新電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)即可(ke)。

三、尋線儀電池電量怎么檢查

為(wei)了方便在使用尋(xun)線儀(yi)時(shi)能及時(shi)發現電(dian)池電(dian)量不足的情況，可以(yi)通過以(yi)下(xia)方法進行電(dian)量檢查：

1、使(shi)用萬用表進行電(dian)壓測試，以確(que)認(ren)電(dian)池是否需要更換；

2、在尋線儀面板上，一(yi)般會(hui)設置一(yi)個(ge)電(dian)量(liang)指(zhi)示(shi)燈(deng)或數(shu)字(zi)提(ti)示(shi)，可以通(tong)過這些指(zhi)示(shi)器來判(pan)斷(duan)電(dian)池是否需要更換(huan)；

3、尋線儀本身會(hui)(hui)具備(bei)報警功能，當電池即(ji)將耗盡(jin)時，會(hui)(hui)發出聲音(yin)或者閃爍提示，以提醒使用者更換電池。
