Tong-test ammeter 钳式电流表 ; 钳式安培计 ; 夹表
universal test ammeter 交直流电流计
ammeter voltmeter test 电流电压测量试验
tong-test t ammeter 钳式电流表
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。
Test and mark the resistance value of the old elements having been replaced (with voltmeter and ammeter) and distribute them in low temperature area.
换下来的元件重新（用压表、电流表）测标其电阻值，配阻用在低温区。
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。
