Lighting

没有你这个标准吖，你百度下“工标网”到那找下有没有地吧！我现在只有这个标准编号:JB/T 7903-1999标准名称:工业射线照相底片观片灯标准状态:现行英文标题:Industrial radiographic illuminators替代情况:JB/T 7903-1995实施日期:2000-01-01颁布部门:全国无损检测标准化技术委员会内容简介:JB/T 7903-1999 本标准等效采用 ISO 5580：1985《无损检测 工业射线照相底片观片灯 最低要求》。 本标准是对 JB/T 7903-95《工业射线照相底片观片灯》的修订。 本标准规定了工业射线照相底片观片灯的技术要求，试验方法，包装、贮存、运输等最低要求。 本标准适用于观察工业射线照相底片的观片灯。 本标准于 1989 年以 GB 11226-89 首次发布，于 1996 年 4 月 14 日调整为 JB/T 7903-95。

The program controller with memory functionNote: because of dentistry chairs can be machine moving parts, and surgical and connect in moving parts, with the movement of dentistry chairs in the operation process, must ensure the equipment within the scope of the exercise, do not have can contact item exists, lest produce an accident.1 dentistry chairs backDirect control of the rotation Angle of dental chair back, its operation methods and processes and direct control of the same rise dentistry chairs, but should be located in the operation control key symbol of dentistry chairs around two direction arrow keys, to control the direction of the arrow to the left for any fadeaway keys. Dental chair back rotation Angle limit position also has the limit.Note: movement of dentistry chairs back due to a larger extent, thus in the operating process, must ensure in movement, within the scope of the goods is not exist, lest produce an accident.Note, 1. Technically speaking, the instrument on the pressure gauge instructions and turbine mobile working pressure with certain difference, its value is just to prolong the working pressure of mobile phone service life greatly.2 the method of setting a limit chair:Press SET key, the flashing lights to SET up a chair, chair, according to former QingChengQingGuo suitable location, click SET key, SET up according to the chair, flashing light supine position, depend on the position behind and press SET key, light, setting out, after setting.2 a S1, S2, memories of setting method: S3Press SET key, SET according to let go, when the indicator light on a chair rises or falls behind, depend on the front or upward to the right place, click the S1, click on the SET key, light setting, S1 Settings. S2 and methods and S1 S3.The program controller with memory functionfunctionalType IV remarkYang, leaning, press the "rise", ""," Yang ", "the key, prone to rise, dental chair, Yang, action, loosen the keys, action to stop. Always press "rise" button, dentistry chairs to limit automatically stop. Master, vice control switch, rise, feet, drop, each key, can achieveThree memory location has three can set the memory location, press any key a memory location button, dental chair automatic operation to prevent preset. Automatic operation process, press any key chair bit motion stops.Press the reset button to reset function, dental chair automatic reset to reset operation process in any position, a chair motion stops.A functional press phlegm sputum (a bit), back light buzzer hint at limit position, has reached to limit position before, if press the stop button, sputum bits in the sputum (movement) a state. If you press the button, the movement of other chair a bit from sputum stop. A process by any sputum, chair bit motion stopsMouthwash press mouthwash, according to the set time, time to stop adding water, water process according to stop water, mouthwash.According to blunt blunt dishes, according to the set time LAN key to time, water rushed dishes. According to blunt blunt dishes process, stop water rushed LAN LAN.Heating and hot pressing, heating, heating process, heating, not the temperature indicator, ChangLiang indicator. Click add hotkeys, exit heating condition, lights out.Film lamp click view pieces lamp lights, film. Then press the button lamp film, film lights.Dental lamp press dental lamp button, oral lamp. Then press the dental lamp, oral lights.
