50mA對應(yīng)0.2V、250mA對應(yīng)1V、1A對應(yīng)4V、5A對應(yīng)20V、10A對應(yīng)40V。（即電流值乘4就是電壓值）<br/>6、當(dāng)未知雜散電流大小時，應(yīng)先置于量程zui大擋，然后逐步減少，直至適當(dāng)測量檔。<br/>7、當(dāng)被測電流大于5A時，儀器只宜進行短時測量，當(dāng)被測電流大于10A時，儀器只宜進行瞬時測量。以免大電流燒毀元件及儀表。<br/>8、測直流雜散電流時,如表頭指針反向偏轉(zhuǎn),對換表筆即可<br/>9、儀器不用時應(yīng)置于“關(guān)"位置。</span></p><p
