1.【电】电压表,伏特计
1.a piece of equipment used for measuring voltage
1.To obtain a KVL equation, we must tally voltage drops in a loop of the circuit, as though we were measuring with a real voltmeter.
要获得一个KVL方程式,我们必须计算该回路中某一环路中的电压降,好像我们是在用一台真正的电压表进行测量一样。
2.The range of a voltmeter may be extended by means of a series resistor called a multiplier as shown in FIG.
如图2所示,采用一种称为倍增电阻的串联电阻器即可扩大伏特表的量程。
3.A voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit.
伏特计是用于测量电路中两点之间电势差的仪器。
4.The holiday detector shall be checked with a DC voltmeter at least once each shift to ensure accuracy.
应至少在每次换班时用直流电伏特计检查一次漏涂检测仪以确保其准确度。
5.The frequency at which the voltmeter's response to an AC signal drops to 70% is often denoted as the "3dB point" (f3dB).
电压表对交流信号的响应降低到70%时的频率常常称为“3dB点”(f3dB)。
6.Our end-users consider the Voltmeter to be unfit from application and claim that the instrument to be replaced by you with a sound one.
我方用户认为该电量计不适于使用,要求你方用一只好的替换。
7.If the current cannot be reduced, use a narrow current pulse and a fast responding voltmeter.
如果不能降低电流的话,使用窄的电流脉冲和快速响应的电压表。
8.Ideally, when a voltmeter is connected to a relatively low impedance circuit in which no voltages are present, it should read zero.
在理想的情况下,当把电压表连接到一个没有电压的、阻抗比较低的电路时,电压表的读数应当为零。
9.The panel is placed in a solar simulator. Negative and positive contacts of the solar panel are connected to a voltmeter.
把板放置在一个太阳模拟器中。无论是与太阳能电池板正面或者反面接触,都连接到电压表。
10.The paper mainly discusses the design principle and chief techniques of a high accuracy programmable digital voltmeter.
