动圈式万用表是一种多量程、多功能的电气测量仪表。但是,由于动圈万用表交直流电压的灵敏度都较低,因此测量中误差较大,读数远远落后于实际值,尤其在电子线路中测量电压。为此本文介绍一简单方法,即用两只不同输入阻抗的动圈式万用表,分别对被测量进行测量,然后将测量结果加以整理计算,便可得到比较准确的测量结果。 Dynamic multimeter is a multi-range, multi-function electrical measuring instruments. However, due to the low AC and DC sensitivity of the moving coil multimeter, the measurement error is large and the reading lags far behind the actual value, especially in electronic circuits. To this end, this article describes a simple method, that is, with two different input impedance of the moving multimeter, were measured on the measured, and then the measurement results are calculated, you can get more accurate measurement results.
