Safety Precautions The following safety precautions should be observed before using this product and any associated instrumentation. Although some instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous conditions may be present. This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury.
states that a shock hazard exists when voltage levels greater than 30V RMS, 42.4V peak, or 60VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring. Users of this product must be protected from electric shock at all times. The responsible body must ensure that users are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact.
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured. The instrument and accessories must be used in accordance with its specifications and operating instructions or the safety of the equipment may be impaired.
The CAUTION heading in a manual explains hazards that could damage the instrument. Such damage may invalidate the warranty. Instrumentation and accessories shall not be connected to humans. Before performing any maintenance, disconnect the line cord and all test cables. To maintain protection from electric shock and fire, replacement components in mains circuits, including the power transformer, test leads, and input jacks, must be purchased from Keithley Instruments.
Introduction This quick reference guide includes summary information on front panel and IEEE-488 operation for the Model 2001 Multimeter. For detailed information, consult the Model 2001 Operator’s Manual, the Model 2001 Calibration Manual, and the Model 2001-SCAN Scanner Card Instruction Manual. All Keithley product names are trademarks or registered trademarks of Keithley Instruments, Inc. Other brand and product names are trademarks or registered trademarks of their respective holders.
Operation Summary Default Configuration The Model 2001 can save from one to ten user setups in memory, depending on the installed memory option. You can select one of the user setups as the power-on default, or have the instrument power up to either of the two factory defaults (optimized for “BENCH” or “GPIB” operation). Reset the instrument to “BENCH” defaults from the front panel by performing the following steps: 1.
Assuming the Model 2001 is set to primary address 16, the instrument can be reset and the reading displayed on the computer CRT from the IEEE-488 bus with the following code fragment: 100 OUTPUT 716;“:syst:pres” 110 OUTPUT 716;“:fetc?” 120 ENTER 716;A$ 130 PRINT A$ Instrument Connections Each measurement function has an appropriate connection scheme. Connections for all functions can be found in Section 3 of the Model 2001 Operator’s Manual.

Multiple Displays Each measurement function has its own set of “multiple displays” shown on the bottom line of the front panel display. To scroll through the multiple displays available for the present function, repeatedly press and release the NEXT DISPLAY key. The same action with the PREVious DISPLAY key does a reverse scroll through the displays. To return to the default reading display, just press and hold either key. Table 1.
