目前我国各部门检验行业所用的各种分析仪器,大都仍采用表头指示与传统的检测操作方法。在实际使用中,需靠人工测试结果进行量化、计算、处理,操作烦琐,可靠性差。往往因操作水平,视觉误差及一次仪表漂移等综合误差影响分析测试精度,为此,我们设计了一种以提高改善老设备性能为目 At present, all kinds of analytical instruments used by various departments in the inspection industry in our country still use the instruction of the meter and the traditional method of testing and operation. In actual use, manual test results need to be quantified, calculated, processed, cumbersome operation, poor reliability. Often due to operational level, visual error and a meter drift and other comprehensive analysis of the impact of error test accuracy, therefore, we have designed a to improve the performance of the old device to improve the
