Fluke offers a series of application notes to help electricians and electronics professionals perform advanced electrical testing with their Fluke digital multimeters (DMMs). Advanced DMMs, such as the Fluke 289 industrial trending digital multimeter and Fluke 287 electronics multimeter, incorporate a variety of s­ophisticated test and measurement capabilities. However, some users may be unsure how those capabilities are used or why the tools are designed as they are. Written and illustrated to help users solve problems and get the most from Fluke test tools, Fluke Application Notes are available through the Fluke website. Dual-impedance capability is one new feature built into the Fluke 289 DMM. Most DMMs sold today for testing industrial, electrical, and electronic systems have high impedance input circuits greater than 1 megohm, having little impact on circuit performance. This is the desired effect for most voltage measurement applications.
