　　4、按‘As Found’功能键，用‘↓’键把光标移动到‘ 1Pt. Switch Test’，按回车键，此时你应看见福禄克压力校验仪开关测试设置屏幕。
　　5、按回车，福禄克压力校验仪输入设置点值‘20’，按回车，此时设置点 类型为Low,缺省设置状态为短路，正好适合本测试(如设置有出入，可以在这里更改)。这些设置条件描述了一 个这样的限位开关：设置点为20°C并且当输入到开关的 温度值低于20°C时，一对触点将会闭合。设置完后，按 ‘Done‘键。
　　6、把光标移动到Tolerance (允许误差)，并输入1°C作为设置点允许误差(SetPoint tolerance);光标移动到 DeadbanF700in (最小死区)，输入1°C作为最小死区值 (minimum deadband);光标移动到DeadbanF700ax (最大 死区)，输入3°C作为最大死区值(maximum deadband)。 现在的福禄克压力校验仪测试设置屏幕应如图4所示。按‘Done’键。
