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.
電流表A1應選用量程爲毫安級電流表或選用數字電流表；電流表A2應選用量程爲50 A以下的安培級電流表或選用數字電流表。
User may select a range of ammeter and another such as wideangle meter, ammeter with overload, digital display meter, voltmeter and tachometer.
電流表量程由用戶指定，可選廣角度表、過載電流表、數顯表、電壓表、轉速表等。

The diffusion current is measured using transistor and digital ammeter instead of operational amplifiers, and the Boltzmann constant is obtained accurately.
在不使用運算放大器的情況下，直接利用晶躰三極琯與數字式電流表測出擴散電流，可以得到較爲準確的玻爾玆曼常量。
