如今的日常生活,电子计算器已经不再是主流的使用物品。但是,仍有不少地区和场合需要使用电子计算器,下面说说电子计算器的保养窍门。

步骤/方法 及时更换电池:在发现所显示的读数暗淡时,表示电池已耗尽,应及时更换。如长时间不使用,应将机内电池取出,以防止电池漏液腐蚀损坏计算器。

防止挤压:敲击或掉落在地上:无论是荧光数码管显示的计算器或是液晶显示的计算器,其显示器件均匀易破碎的玻璃器件,应严妨挤压敲击或掉落,以免损坏。

留意使用环境:液晶显示的计算器只能在0-40摄氏度的气温范围内使用,并且不宜在强光下使用,由于阳光中的紫外线会加速液晶屏的老化。也不宜在湿润和有腐蚀气体的环境中使用和存放,以免损坏机件。

留意防尘:用毕后要装入皮套或塑料套内,以防止灰尘侵入。如面板上有灰尘,可用软布轻轻擦拭,切不可用汽油、乙醇、香蕉水等化学试齐擦拭。
