  • Page 5: Safety Precautions

    SAFETY PRECAUTIONS The following safety precautions should be observed before using this product and any associated instru- mentation. Although some instruments and accesso- ries would normally be used with non-hazardous volt- ages, there are situations where hazardous conditions may be present. This product is intended for use by qualified person- nel who recognize shock hazards and are familiar with the safety precautions required to avoid possible in-...
  • Page 6 Only properly trained service personnel may perform installation and service procedures. Keithley products are designed for use with electrical signals that are rated Installation Category I and In- stallation Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664.
  • Page 7 Do not connect switching cards directly to unlimited power circuits. They are intended to be used with im- pedance limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit fault current and voltage to the card.
  • Page 8 Do not exceed the maximum signal levels of the in- struments and accessories, as defined in the specifi- cations and operating information, and as shown on the instrument or test fixture panels, or switching card. When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.
  • Page 9 Keithley Instruments to maintain accuracy and functionality of the product.) If you are unsure about the applicability of a replace- ment component, call a Keithley Instruments office for information. To clean an instrument, use a damp cloth or mild, water based cleaner.
  • Page 10: Control Summary

    CONTROL SUMMARY RANGE Use UP and DOWN to manually select desired mea- surement range; 3mV, 30mV, 300mV, 3V, or 30V. Present range is displayed on status line. Press AUTO to turn auto-range on or off. Unit upranges at overflow point (±3,029,999 counts) and downranges at 9.33% of full range when AUTO is enabled.
  • Page 11 to scroll through selections, ENTER to select, or ESC to cancel selection. TRIGGER MODE: select multiple (continu- ous with one trigger) or one-shot (one read- ing per trigger). TRIGGER SOURCE: select external, manual, disabled, or IEEE-488 X, GET or talk triggers. TRIGGER DELAY: program desired trig- ger delay (time between trigger and read- ing in one-shot trigger mode): 0sec-...
