Based on the same high speed, low noise A/D converter technology as the Models 2000, 2001, and 2002, the 2010 is the latest addition to Keithley's Series 2000 line of high performance digital multimeters. The 2010 has 15 built-in measurement functions, including DCV, ACV, DCI, ACI, 2WΩ, 4WΩ, dry circuit resistance, temperature (with either thermocouples or RTDs), frequency, period, ratio, continuity measurement, and diode testing. This multi-functional design minimizes added equipment costs. Creating a self-contained multipoint measurement solution is as simple as plugging a 2000-SCAN or 2001-TCSCAN scanner card into the option slot in the 2010’s back panel. This “plug-in” approach eliminates the need for a separate scanner and significantly reduces programming and setup time in applications involving a limited number of test points. For larger applications, the 2010 is compatible with Keithley’s Series 7000 switch matrices and cards.
