In the picture above you can see the frequency meter, and the large wooden ammeter on the wall. 上面图片中可以看到频率计,和大木电表墙壁上。
The collectivity structure design, operational principle and Innovation points of JMX-29F Ammeter(AMM) Relay are present. 文章介绍了JMX-29F电表继电器的总体结构设计、动作原理和相关的创新点。
This article introduces the principle of current measurement for shunt ammeter and feedback ammeter. 介绍了分流式和反馈式电流表(AMM)测量直流电流的基本原理。
Note that the current must flow through the ammeter in order to reach the circuit. 注意,电路中的电流必须通过电流表(AMM)以测量到读数。
