袖珍式液晶显示电子计算器具有计算迅速、准确,操作简便、容易掌握、轻便、耗电省等优点,因此,越来越受到人们的欢迎和使用。但很多人对如何选购和正确使用不甚了解,现作一简要介绍。 一、选购 1.根据使用环境进行选择 液晶显示的计算器的工作温度在0℃~40℃范围内。如果低于此温度情况下使用,不但运算速度明显缓慢,甚至还将产生显示模糊、缺划等不正常现象。在寒冷的北方宜选用发光二极管显示或荧光数码管显示的计算器。
Pocket LCD electronic calculators with the calculation of rapid, accurate, easy to operate, easy to grasp, lightweight, power consumption and other advantages, therefore, more and more people are welcome and use. However, many people do not understand how to purchase and use it properly. A brief introduction is now made. First, the purchase 1 according to the use of the environment to select the liquid crystal display calculator operating temperature 0 ℃ ~ 40 ℃ range. If the temperature is lower than the use of the case, not only significantly slower computing speed, and even will have a display fuzzy, lack of planning and other irregularities. In the cold north should use LED display or fluorescent digital tube display calculator.
