用电子天平检定/校准M1级砝码时发现的问题

Problem of Appraising and Calibrating M1 Grade Poise by Electronic Balance

携电子天平去企业检定/校准M1级砝码,在某些企业,电子天平无法正常工作,受干扰大,读数很不稳定,影响检定工作。文章分析了影响电子天平正常工作的干扰因素,认为主要影响来自企业大型设备频繁启动,造成电磁干扰。通过采取抗干扰措施,使检测工作能准确、顺利地进行。

Electronic balance cannot work normally in some corporations when appraising and calibrating M1 grade poise due to big interference and unstable reading. The interference factors were analyzed. The result shows that the main effect is the electromagnetic interference coming from frequent startup of large equipment. Therefore, appraising operation can be performed accurately and smoothly by adopting anti-interference measures.
