digital ammeter

基本解释

For ammeter A1, milliamperemeter or digital ammeter shall be used while for ammeter A2 amperemeter upto 50 A or digital ammeter shall be used.
电流表A1应选用量程为毫安级电流表或选用数字电流表；电流表A2应选用量程为50 A以下的安培级电流表或选用数字电流表。
User may select a range of ammeter and another such as wideangle meter, ammeter with overload, digital display meter, voltmeter and tachometer.
电流表量程由用户指定，可选广角度表、过载电流表、数显表、电压表、转速表等。

The diffusion current is measured using transistor and digital ammeter instead of operational amplifiers, and the Boltzmann constant is obtained accurately.
在不使用运算放大器的情况下，直接利用晶体三极管与数字式电流表测出扩散电流，可以得到较为准确的玻尔兹曼常量。
