The informa- tion is organized as follows: • Feature overview • Manual addenda • Safety symbols and terms • Specifications • Inspection • Options and accessories If you have any questions after reviewing this information, please contact your local Keithley representative or call one of our Applications Engineers at 1-800-348-3735 (U.S. and Canada only). Worldwide phone numbers are listed at the front of this manual. 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. 2000-900 (J - Aug 2010) BOOK.fm Page 3 Wednesday, October 12, 2011 12:29 PM 1-3 Manual addenda Any improvements or changes concerning the instrument or manual will be explained in an addendum included with the manual. Be sure to note these changes and incorporate them into the manual. Safety symbols and terms The following symbols and terms may be found on the instrument or used in this manual. The ! symbol on the instrument indicates that the user should refer to the operating instructions located in the manual. The symbol on the instrument shows that high voltage may be present on the termi- nal(s). Use standard safety precautions to avoid personal contact with these voltages. The WARNING heading used in this manual explains dangers that might result in per- sonal injury or death. Always read the associated information very carefully before perform- ing the indicated procedure. The CAUTION heading used in this manual explains hazards that could damage the in- strument. Such damage may invalidate the warranty. 2000-900
