摘要

由于缺乏相应的可编程接口，手持式数字万用表的自动检测一直是电气计量领域的难题。本文研制了一种多通道数字万用表自动检测装置，可同时对7种不同型号的数字万用表进行校验。以直流电压为例，将采用前一种校准方法的校准结果与使用该装置后的校准结果进行了比较。结果表明，所研制的装置能够满足手持式数字万用表的日常校准，保证了校准的准确性。在保证精度的前提下，效率提高70%。

Development of multi-channel automatic digital multimeter calibration device

The automatic detection of hand-held digital multimeter has always been a difficult problem in the field of electrical metrology due to the lack of corresponding programmable interface. In this paper, a multi-channel automatic detection device for digital multimeter is developed, which can simultaneously calibrate seven different types of digital multimeter. Taking DC voltage as an example, the results of calibration using the former calibration method are compared with those after using the device. The results show that the developed device can meet the daily calibration of hand-held digital multimeter and ensure the calibration. On the premise of accuracy, the efficiency is increased by 70%.
