在另一些情况下，则可以使用REL(零点)功能将其从读数中减去，或者简单地使用内置的零点抑制功能(如果仪器具有此功能的话)将其消除。
In other cases, it can either be subtracted from the reading by using the REL (zero) feature or simply canceled out by using built-in zero suppression if the instrument has this feature.
然而，用这种方法得到的零点只能用于校验的目的，而不适合用在仪器的最终应用中。
However, the zero established in this manner is useful only for verification purposes and is of no value in the end application of the instrument.
星载遥感仪器扫描部件具有“极小子样、零失效”的特点，其可靠性分析与评估一直是工程实践中的技术难题之一。
The reliability and evaluation of Scanning Components for Satellite-borne Instrument is difficult in engineering because of extremely small sized and zero-failure.
