The Keithley 2001 Series is a 7.5-digit multimeter engineered for precision measurement and automated data acquisition in laboratory, engineering, and system integration environments. Built on a 28-bit A/D converter, it delivers true 7.5-digit resolution across DC voltage, AC voltage, current, resistance, frequency, and temperature measurements. The instrument supports single-range DC voltage measurement from 1 µV to 20 V, eliminating range-shift errors and delays. Optional scanning capabilities enable multi-point automated testing with up to ten measurement points, reducing test cycle time and operator intervention.
