Nzira yekuona kana lining yechoto chemukati chabviswa

A. Kana hupamhi hwechigadziko chevira huri pasi pe50 mm, inofanira kubviswa.

B. Kana iyo alarm yearamu yakawandisa, simbisa kuti mudziyo wearamu hauna kukanganisa. Panguva ino, choto chinoda kubviswa.

C . Kana iri pasi peimwe yakatemerwa DC voltage, huremu hwesimbi yakanyungudutswa mumatanho ekutanga uye ekupedzisira akaenzana, vhezheni yechoto haina kukukurwa kwenzvimbo kuri pachena, iyo DC ikozvino inokwira ne15-20%, uye vhezheni yevira inofanira kubviswa. Panguva yekushandiswa, kana iyo DC ammeter neDC voltmeter ichizununguka zvakanyanya, kana iyo DC ammeter ikaramba ichikwira uye iyo DC voltmeter ikaramba ichidonha, zvinoratidza kuti vhezheni yevira yadeuka, uye matanho echimbichimbi anofanirwa kutorwa nekukurumidza.
