發動機內部出現損傷需要內窺鏡來幫忙，它是維護的一個重要組成部分，能及時掌握情況，讓管理人員提前做好換發動機的準備。經過統計發現，很多維護都是根據內窺鏡的檢查結果決定是否更換發動機。

The damage inside the engine needs the help of endoscope. It is an important part of maintenance. It can grasp the situation in time and let the managers prepare for replacing the engine in advance. After statistics, it is found that many maintenance are based on the inspection results of the endoscope to decide whether to replace the engine.

采用的微凸鏡制造工藝，大大提高了感光性和分辨率，圖像的清晰度大大提高了，無法看到的黑暗的地方也能看清楚圖像。存儲卡替代了以前使用傳統硬盤記錄的方法，集拍照，錄像功能為一體，檢測起來更加方便，存儲的能力也有所提升。

The micro convex mirror manufacturing process greatly improves the sensitivity and resolution, greatly improves the definition of the image, and can see the image clearly in the dark places that can not be seen. The memory card replaces the traditional hard disk recording method, integrates the functions of photographing and video recording, makes detection more convenient, and improves the storage ability.

在使用時要嚴格遵守設備保管制度，沒有經過同意，不允許擅自使用，避免設備出現損壞或者鏡頭點入機內；工作前、工作場地轉移、工作后都要清點設備，防止工作丟失或者掉入發動機內；設備在使用時必須接地，防止靜電損壞設備。當器件內部溫度高于規定的溫度時，需要等待冷卻到規定的溫度之后才開始工作。設備使用完后在關機前要將光亮度調到小,讓設備有足夠的冷卻時間。
