ammeter

An instrument used to measure the flow of current in a circuit is called an ammeter.

用来测量电路中电流流量的仪器叫做电流表。

Since the voltage drop across the ammeter is negligible, essentially all the test voltage appears across R.

由于安培计上的电压降可以忽略，所以所有的测试电压都出现在电阻R上。

If the component or material breaks down, all the voltage would be applied to the ammeter's input, possibly destroying it.

如果元件或材料发生击穿，全部电压都会加到安培计的输入端，从而可能将其损坏。

To start with, you need to break the circuit so that the ammeter can be connected in series.

开始时，你需要断开电路，以让电流表可以串入。

The guard can be used to isolate the high impedance input lead of the ammeter from leakage current due to voltage sources.

保护可以用来把安培计的高阻输入引线和由电压源引起的泄漏电流隔离开来。

To measure the offset of a switch card, connect the output of the card to a pico ammeter or electrometer.

若要测量开关卡的偏移电流，请将卡的输出连接到一台皮安计或静电计。

The protection circuit should be enclosed in a light-tight shield. The shield should be connected to the low of the ammeter.

保护电路应当做遮光屏蔽，且屏蔽要接到安培计的低压端。

Since the voltage burden of the electrometer ammeter or picoammeter is less than 1mV, the diodes won't conduct.

由于静电计、安培计或皮安计的输入端压降小于1mV，这两个二极管不会导通。

To see how changes in source capacitance can affect noise gain, let's again refer to the simplified ammeter model in Figure 2-15.

为了了解源电容如何影响噪声增益，再来看一下图2-15中的简化的安培计模型。

Connect the battery and ammeter to the starter as shown in the illustration.

按说明连接电池和安培计到起动机上。

Comparatively, RF transcribe ammeter system is more effective, in the system, RF data transportation module plays an important role.

相比较而言，新型的射频抄表系统极大地提高了抄表的效率，在这个系统中射频数传模块起着关键的作用。

The controlling box is composed of secure shell , flameproof elements ( signal indicator , ammeter, button, switch ) terminals, etc.

控制箱由增安型外壳，隔爆型元件（信号灯、电流表、按钮、开关）及接线端子等组成。

He is able to use the instruments for oil pressure, water temperature, fuel gauge and ammeter.

他会使用测量油压、水温、燃料耗量以及电流的各种仪表。

Hi, our ammeter doesn't work. Could you send someone here to check it out?

你好，我们家电表好像坏了，你能派人来看一下吗？

It is convenient to include the functions of a voltmeter , ammeter, and ohmmeter within one instrument.

人们把伏特表，安培表，欧姆表集中在一只仪表内是非常方便的。

However, in spite of all this similarity between a voltmeter and an ammeter there are also important differences.

可是尽管伏特表与安培表之间有这些类似之处，但还有若干重要的差别。

In this method, a constant voltage source (V) is placed in series with the unknown resistor (R) and an ammeter (IM).

在此方法中，恒压源（V）与未知电阻（R）和安培计（IM）相串联。
