When making a choice about the optimum digital multimeter to purchase or to use for a given application, there are a number of parameters and specifications that need to be assessed.
DMM specifications: There are many specifications used to define the performance of a digital multimeter. These include the measurements that can be made, the ranges, number of digits in the display as well as the mechanical details including size, etc. digital multimeter specifications.
DMM accuracy: One of the key specifications for a digital multimeter is the accuracy. This has several elements to it and requires careful consideration in some applications. <
Digital multimeters are widely used and very useful items of test equipment. They enable measurements of quantities such as current, voltage and resistance to be made very quickly and easily. In addition to this, many DMMs are able to measure other useful parameters, making these items even more useful. While they do not allow more complicated measurements to be made, if many engineers were allowed only one item of test equipment, it would probably be the digital multimeter.
