How to make a mini Voltage Current Mete 手工DIY制作实用电压电流测试表

[@joeyeh2802]

您好！
我製作了一個跟您一樣的電壓電流測量表，可是當我連接DC小馬達時確顯示不出電流數值。請問是否要調整電流調整鈕或其他方式？
謝謝

這樣可以直接拿來 測量 機車 電流 嗎?

你好 請教一下，我按照步驟做，可是打開開關 (A)的部分會顯示數字，想請問有哪邊接錯嗎？

這是我的狀況，

[@KJDOT]

有两种可能，一个是线路也许有接错的地方，二是这个模块也许坏了

[@joe650611]

KJDOT 好的 謝謝，線路檢查過了，可能是模組的問題！

[@joe650611]

KJDOT 找到原因了，我買50a的變成要裝分流器，裝了就好了instagram.com/p/Bhl3bEbFfJS/
