inherit; font-family: 微軟雅黑;"> 1. 要在測試前插好電流測試鉗，嚴禁先夾被測信號后插入電流鉗插座，這相當于電流測試鉗二次開路，容易產(chǎn)生開路高壓，損壞儀器。測試完成后要先摘下所有電流測試鉗再拔下與主機相連的插頭。</span></p><p style="margin-top: 2px; margin-bottom: 2px; padding: 0px;

line-height: inherit; font-family: 微軟雅黑;"> 2. 測試鉗為保證各通道精度，應一一對應，要把各電流鉗正確插入一</span>與之對應的插座。交換不同輸入插座，會降低了測試精度，但交叉后一般測試精度也不會超出在±2%。</p><p style="margin-top: 2px; margin-bottom: 2px; padding: 0px; border:
