The Model 2000 is a 6 ½-digit high-performance digital multimeter. It has 0.002% 90-day basic DC voltage accuracy and 0.008% 90-day basic resistance accuracy. At 6½ digits, the multimeter delivers 50 triggered readings/sec over the IEEE-488 bus. At 4½ digits, it can read up to 2000 readings/sec into its internal buffer. The Model 2000 has broad measurement ranges: • DC voltage from 0.1µV to 1000V. • AC (RMS) voltage from 0.1µV to 750V, 1000V peak. • DC current from 10nA to 3A. • AC (RMS) current from 1µA to 3A. • Two and four-wire resistance from 100μΩ to 120MΩ. • Frequency from 3Hz to 500kHz. • Thermocouple temperature from -200°C to +1372°C. Some additional capabilities of the Model 2000 include: • Full range of functions — In addition to those listed above, the Model 2000 functions include period, dB, dBm, continuity, diode testing, mX+b, and percent. • Optional scanning — For internal scanning, options include the Model 2000-SCAN, a 10-channel, general-purpose card, and the Model 2001-TCSCAN, a 9-channel, thermocouple card with a built-in cold junction. For external scanning, the Model 2000 is compatible with Keithley's Model 7001 and 7002 switch matrices and cards. • Programming languages and remote interfaces — The Model 2000 offers three programming language choices (SCPI, Keithley Models 196/199, and Fluke 8840A/8842A) and two remote interface ports (IEEE-488/GPIB and RS-232C). • Reading and setup storage — Up to 1024 readings and two setups (user and factory defaults) can be stored and recalled. • Closed-cover calibration — The instrument can be calibrated either from the front panel or remote interface.
