The industrial endoscope must be checked and calibrated before use, so as to improve the accuracy of future inspection. If they are used rashly, it may bring unpredictable losses. Talking about the inspection before the calibration of endoscope.

1.在足夠的照明下觀察內(nèi)窺鏡的外表面。電鍍零件的表面應(yīng)光滑，無刮擦。表面應(yīng)均勻且顏色一致。不應(yīng)有明顯的劃痕，燒傷和明顯的裂縫。噴塑部件的表面應(yīng)平整光滑，顏色應(yīng)均勻，底部不應(yīng)有起泡，剝離和開裂。

1. Observe the external surface of the endoscope under sufficient illumination. The surface of electroplated parts shall be smooth without scratch. The surface shall be uniform and uniform in color. There should be no obvious scratches, burns and obvious cracks. The surface of spray parts shall be smooth and even in color, and the bottom shall be free from blistering, peeling and cracking.

2.照明點處于正常工作距離。將白板放在被測端，用浸入的透射光或內(nèi)窺鏡自身的光源照亮。從目鏡或肉眼觀察。照明點應(yīng)填充視野，而沒有明顯的明暗區(qū)域。

2. The lighting point is in the normal working distance. The white board is placed on the end to be measured and illuminated by the immersed transmission light or the light source of the endoscope itself. Observe from eyepiece or naked eye. Lighting points should fill the field of vision without obvious light and dark areas.
                

3.在正常工作距離下，視場燈條（適用于光纖內(nèi)窺鏡）的方向標(biāo)記，將白板放在被測端，用浸入的透射光或內(nèi)窺鏡自身的光源照亮，并從目鏡，視場亮條箭頭指示，方向標(biāo)記的方向應(yīng)在上方。

3. Under the normal working distance, the direction mark of the field of view light bar (applicable to the optical fiber endoscope) shall be placed on the measured end, illuminated by the immersed transmitted light or the light source of the endoscope itself, and indicated by the eyepiece and the arrow of the field of view light bar. The direction of the direction mark shall be above.

4.在正常工作距離，脫膠或發(fā)霉的地方，將白板放在被測端上，將光源浸入透射光或內(nèi)窺鏡中進行照明，并從目鏡或監(jiān)視器上用裸眼觀察，無明顯脫膠或發(fā)霉現(xiàn)象。

4. Place the white board on the tested end at the normal working distance, where degumming or mildew occurs, immerse the light source in the transmitted light or endoscope for illumination, and observe with naked eyes from the eyepiece or monitor, without obvious degumming or mildew.

在檢查這些設(shè)備之前必須完成！正確的使用好內(nèi)窺鏡是我們檢測工作效率的保證！

This must be done before checking these devices! Correct use of endoscope is the guarantee of our detection efficiency!
