下拉application菜单选measurement后“spectra measurement is running ”, 此时开始出现spectra measurement窗口“No accessory”以上正常 关键地方马上到了: 下拉measure菜单选background后报错: “waited for 10.0 sec,but the process has troubled。 Suspected points are: 1 moving mirror is stopped。 2 moving mirror is not released 3 unequipped attachment is demanded。 (error code A028)”
