MA4210型尿液分析仪是一种半自动分析仪器。它具有故障自检功能,出现故障时能自动打印故障代码。在日常使用时经常出现trouble-4(光度不足)。其常见原因: (1)钨灯烧坏 仪器的光源是一只直流12V、10W的钨灯,电流过大冲击或其它因素可造成钨灯灯丝烧断,更换一只新的灯泡即可。安装时应注意戴上手套或在灯泡上垫上干净的软纸,保证灯泡表面的光洁。 (2)钨灯低效 测量灯泡两端12V电压正常,观察灯泡发光较暗。清除灯泡表面灰尘和污物,安上灯泡后故障依旧。便可判定灯泡老化、低效,不能继续使用,更换一只新的即可。 (3)透光孔污染 仔细擦拭灯泡、反射罩、测量灯泡和直流12V电源均正常时,查透光孔、
MA4210 type urine analyzer is a semi-automatic analyzer. It has a fault self-test function, fault code can be automatically printed when a fault occurs. Trouble-4 often occurs in everyday use (low light). The common reasons: (1) burn tungsten lamp light source is a DC 12V, 10W tungsten lamp, the current is too large impact or other factors can cause the tungsten lamp filament blow, you can replace a new light bulb. Attention should be paid when installing gloves or light bulbs on a clean soft paper pad to ensure that the light bulb surface smooth. (2) inefficient measurement of tungsten lamp 12V voltage at both ends of the bulb is normal, observe the dark light bulb. Clear the surface of the lamp dust and dirt, after the light bulb failure still. Can determine the lamp aging, inefficient, can not continue to use, you can replace a new one. (3) light hole pollution carefully wipe the bulb, reflector, measuring light bulb and DC 12V power supply are normal, check through the light hole,
