探測鉗控制及指示

控制及指示

描述

電流流動記號。箭頭顯示探測器的極性來測量電流的流
動從正極到負極。
零位調整。當沒有通電時,轉動來調整探測棒輸出端至
零位。這也可以用在抵銷 DC 信號成分。測量 AC 數值時
不須做零位調整除非你的機器無法離析 DC 部分。
關 閉 / 範 圍 開 關 。 把 開 關 從 關 閉 滑 至 為 5mV/A 或
50mV/A 的範圍。無論選擇哪一個範圍,都會啟動探測
器,綠色燈將亮起。如果燈沒有亮,請參考電池注解及
安裝電池資料。
電池顯示燈。當探測棒是開啟時,綠色的電池顯示燈將
亮起。
過載指示燈。如果測驗的數值超出選擇的範圍檔負載量,
那紅色過載顯示燈將亮起並且連續閃爍警示。如可以,
把探測棒調回 5mV/A 或者把探測棒移開電路。

50mV/A

5mV/A
