各位使用者您好：

6/19 (四) 發生有使用者於 B662 NMR 進行高溫變溫實驗後，未依規定將溫度調回常溫，致使儀器目標溫度長時間維持在 313 K（40 °C）。
此情形已於當日晚間 21:20 由同學發現並協助將溫度調回常溫設定。

提醒各位使用者：

• 6/19 (四) 13:00–21:20 期間於 B662 NMR 所收集之光譜皆屬非常溫條件，若對數據有疑慮，請自行評估是否需要重測。
• 為避免類似情形再次發生，已於電腦下方加貼溫度提醒標示，請各位操作前後務必確認儀器溫度已恢復至常溫。

請各位使用者共同遵守操作規範，維護儀器正常運作。
如有任何疑問，請隨時與管理人員聯繫。

Dear Users,

On June 19 (Thursday), a user conducted a high-temperature variable-temperature experiment on the B662 NMR but did not follow the required procedure to reset the temperature to ambient afterward. As a result, the instrument’s target temperature remained at 313 K (40 °C) for an extended period.
This situation was discovered by another user at 21:20 that evening, who assisted in restoring the temperature to ambient.

Please be reminded:

• Spectra collected on the B662 NMR during 13:00–21:20 on June 19 (Thursday) were acquired under non-ambient temperature conditions. If you have any concerns about the data quality, please evaluate whether remeasurement is necessary.
• To prevent similar situations from happening again, a temperature reminder label has been posted below the computer. Please always ensure that the instrument temperature has returned to ambient before and after your measurements.

We appreciate your cooperation in following operating procedures to maintain the instrument in proper working condition.

If you have any questions, please feel free to contact the staff.
