求翻译：　　表示器件在给定电源电压下所消耗的静态功率，Pd通常定义在空载情况下。是什么意思？

Said device at a given supply voltage static power consumption, Pd is usually defined with no load.

expressed in a given power supply voltage devices under the static power consumption, Pd are usually defined in empty cases.

　　Results in the use process in the instrument measuring appliance to be able to involve to the measuring range results in the question. In order to obtain the fixed voltage to result in the output, must change the operational amplifier to result in the enlargement factor. For example: When some ope
