我们的日常工作经常要从显示屏幕上读取测量数据，如汽车仪表盘上用数字表示的速度、实验室温度，或者是示波器上所显示的读数。尽管我们很相信这些测量数据，但它们不是百分之百准确的，汽车速度计上所显示的速度很容易出现几公里/小时的误差，温度测试也可能会相差好几度。速度计上的小小误差还不是什么大问题，但当我们建立一个*的测量和数据采集系统时，认识可能存在的误差是非常重要的。任何数字测量系统都存在一个局限，即代表实际测量值的数字是有限的，其数量由所使用的位数决定。

分体式空调器使用的遥控器上一般设有高、中和低三档风速供选择。可依室内的温度要求，通过调节空调器的风速档来达到调节制冷或制热的目的。空调停机原因：空调器无论由于何种原因而停机(如突然断电、人为停机等)，由于一般空调器均设有停机的时间延迟器(延迟时间约3min)，这时这类空调器停机后虽可马上开机，但需过3min后才能运转。但对无时间延迟器的空调器，停机后不能立即开机，务约3min，才能重新开启空调器，否则可能造成启动电流过大，烧毁熔丝，甚至烧毁压缩机电机的后果。
