一、测温显示仪表回程误差的种类回程误差是一种系统误差。在测温显示仪表中,可分为示值回程误差和控制回程误差两种。 (一)示值回程误差就温度仪表来说,产生示值回程误差的因素是滑动摩擦和系统惯性。通常影响示值回程误差的因素往往以其中的某个为主,其他因素为辅甚至可忽略不计。 First, the temperature shows the type of instrument backhaul error Backhaul error is a systematic error. In the temperature display instrument, can be divided into two kinds of indication return error and control return error. (A) Indication return error On the temperature meter, the factors that produce backlash error are sliding friction and system inertia. Often the factors that affect the return error of indication are often dominated by one of them, and other factors are even negligible.
