  • Page 6: Safety Precautions

    Keithley Instruments products are designed for use with electrical signals that are rated Measurement Category I and Measurement Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and data I/O signals are Measurement Category I and must not be directly connected to mains voltage or to voltage sources with high transient over-voltages.
  • Page 7 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. Standard fuses with applicable national safety approvals may be used if the rating and type are the same.

  • Page 70: Common Commands

    SCPI commands In the Model 6517B, you are given access to control settings that are hidden on other instruments. Because the instrument has more control points available, it requires more commands than its counterparts to perform comparable tasks.

  • Page 71: Scpi Command Syntax

    However, you do not have to use the mixed capitalization. The Model 6517B accepts commands in any combination of upper and lower case. For example, all of the following are valid forms of the SENSe1:VOLTage[:DC]:REFerence command:...
  • Page 72 A leading colon instructs the Model 6517B to interpret the command starting at the root (highest level) of the command tree. Since the Model 6517B also starts at the root each time you send it a new command, the leading colon is not needed (although the instrument will accept it if you send it).

  • Page 73: Scpi Signal-Oriented Commands

    This query command is used to request the latest post-processed reading. After sending this command and addressing the Model 6517B to talk, the reading will be sent to the computer. This command does not trigger a measurement, it simply requests the last available reading.
