Feature overview
The Model 2000 is a 6½-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 measure
-
ment 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 pro-
gramming 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.
