摘要
本文介绍一种扫描开关,在保证低热电势的前提下,方便增加通道数量,同时可以通过扫描开关的硬件和软件实现热电偶双极法和同名极法检定的转换,无需用户重新连接,方便灵活。
The paper describes a scanning switch.It is easy to increase the number of channels on condition that ensuring low thermal EMF.At the same time by setting hardware and software of the scanning switch it is also easy to switch between the bipolar method and the same-polarity method for thermocouple calibration,without requiring the user to reconnect.
