二、基本功能定义
1、按键操作
ON/OFF/前进按钮 | 开关机 |
前进按钮 | |
设定/确认/后退按钮 | 确认 |
后退按钮 |
2、系统功能
1) E2PROM(24LC02)侦测：若无此参数将显示E2PROM出错画面“ErrE”；
2) 校正检测：检测是否进入校正模式,通常在出厂前使用；
3) 报警提示：高压警示；操作错误报警；当工作电压小于4.2±0.2V时，显示“Lo”低压报警2s后自动关机；
4) 处于待机状态1min后,将自动关机；
5) 支持USB功能，通过USB接口支持PC端健康管理软件。
3、技术参数
1) 测量范围：1.1~33.3mmol/L（20~600mg/dL），允许误差:20% ；
2) 测试环温：5℃—40℃
3) 需血量：3uL
三、test method
1. Before measuring blood glucose, prepare the following items, blood glucose meter, blood glucose test paper, disinfection cotton ball, blood collection pen and blood collection needle.
2. Take out the test paper and insert it into the blood glucose meter, and insert the end with magnetic strip into the blood glucose meter. Insert the blood glucose meter display screen to display all call signs. After about 1 second, the last measurement result will be displayed, and then the previous test paper code will be displayed. Confirm whether the test paper code is consistent with the code shown on the test paper bottle body. The blood drop symbol will appear after confirmation. (when inserting the test paper, please do not touch the blood suction port of the test paper with your fingers, so as not to pollute the blood suction port of the test paper and cause inaccurate measurement results)
3. For blood collection, please carefully check whether the protective cover of the blood collection needle is intact before use. If the protective cover falls off or is loose, please replace a new blood collection needle. Then "load" the blood sampling needle and clean the finger pulp. (before cleaning the finger, massage the blood collection part of the finger to facilitate blood collection.)
4. Put the blood drop on the finger close to the blood collection port of the test paper (please be careful not to touch the blood collection port of the test paper with the finger skin, so as not to affect the accuracy of measurement). After confirming that the blood drop symbol appears on the display screen, gently touch the blood collection port of the test paper. After the blood collection window is full, the blood glucose meter starts to measure, and the measured value will be displayed after 5 seconds. (pull the test paper out of the blood glucose meter, and the blood glucose meter will shut down automatically. Please discard the used test paper properly.
