ammeter test 电流表试验
tong-test t ammeter 钳式电流表
ammeter voltmeter test 电流电压测量试验
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。
The traditional measure method of the power withstand test is to use the voltage meter, ammeter, power analyzer, frequency analyzer etc to measure the waveform and parameters of the power signals.
传统的工频耐压试验是通过电压表，电流表，功率分析仪，频谱分析仪等等来分别测量波形及其各个参数的。
