LEEM-2 Ginin Ammita da Voltmita

Pointer type DC ammeter da voltmeter ana sake gyara su daga kan mita. Yawan mita yawanci galvanometer ne mai ɗauke da wutar lantarki, wanda kawai zai bada izinin ƙarancin micro ampere ko matakin milliampere ya wuce. Gabaɗaya, yana iya auna ƙananan ƙaramin ƙarfin wuta da ƙarfin lantarki kawai. A amfani mai amfani, dole ne a canza shi don faɗaɗa kewayon saiti idan zai auna babban ƙarfin yanzu ko ƙarfin lantarki. Yakamata a daidaita mitar da aka gyara tare da mizanin ma'auni kuma yakamata a tantance matakinsa daidai. Wannan kayan aikin yana samarda cikakkun kayan aikin gwaji don sake gyara micro ammeter zuwa milliammeter ko voltmeter. Abun gwajin yana da wadata, batun a bayyane yake, tsayayye ne kuma abin dogaro, kuma ƙirar tsarin ta dace. Ana iya amfani dashi galibi don gwajin faɗaɗa ilimin ɗaliban makarantar tsakiya ko gwajin kimiyyar kimiyyar lissafi da ƙirar ƙira.
