任何仪表装备的最后一级都是用简单而又易懂的方法提出测量数据。如果立即需要信息,则可在视觉上提供给操作者,偶尔,为了更方便,也可把它表达成可以听见的信号,可见信号的选择范围很广,从表中指针的机械位移,阴极射线示波管中光点的电位移,到数码管和电传打字等等。可以听见的信号包括开—关音讯号,数据的喇叭或耳机表达法等。被测数据的直接显示仪表,通常认为属于指示器的范畴,在一些场合下,需要存储被测
The last level of any instrumentation is to present measurement data in a simple and understandable way. If information is needed immediately, it can be visually provided to the operator, and occasionally it can be expressed as an audible signal for convenience, with a wide range of signal options, from the mechanical displacement of the hands of the watch to the cathode ray Oscilloscope light spot in the electrical displacement to the digital tube and teletype and so on. The audible signals include on-off tone signals, data on the speaker or headphone representation, and more. Direct display of the measured data instrument, usually considered part of the scope of the indicator, in some cases, the need to store the measured
