整机的量程调节和零点调节在D/A转换电路中实现。
The range adjustment and zero-point adjustment of the metre are both realized in D/A conversion circuitry.
这种功能能够快速地检查和调节放大器的零点。
This feature allows fast checking and adjustment of the amplifier zero.
表指示器应当是平衡式的并有微调，这样零点漂移可以不用调节可动元件来修正。
Gauge Pointers shall be balanced and provided with a micrometer adjustment so that zero shift may be corrected without adjusting the movement.
准椭圆函数滤波器的传输零点，可以位于阻带内的任意位置处，这能更加灵活地对滤波器的带外抑制度进行调节，其矩形系数可以做得很高。
The transmission zeros(TZ) of Quasi-elliptic function filter could be placed in any position, so the attenuation out of band is controllable, then a high selection performance could get.
