  • Page 7: 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 8 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.

The first two commands set the output pulse width on line 1 and program line 2 for falling edge input triggers. The second two commands assert and then wait for a trigger on lines 1 and 2 respectively.

  • Page 101: How Do I Store Measurements In Non-Volatile Memory

    ® Series 2600 System SourceMeter Instruments User’s Manual Appendix B: Frequently Asked Questions How do I store measurements in non-volatile memory? A Series 2600 SourceMeter has two non-volatile buffers for measured readings, source values, and timestamps: NV Buffer 1 ( nvbuffer1 ) and NV Buffer 2 ( nvbuffer2 ). Data stored in these buffers will not be lost when the Series 2600 is turned off.

  • Page 102: How Do I Stack Channels To Output Higher Voltage

    How do I stack channels to output higher voltage? The maximum output voltage of a Model 2601 or Model 2602 channel is 40.4, and the maximum output voltage of a Model 2611/2612 or 2635/2636 channel is 202V. Higher voltage can be output by stacking (connecting in series) channels.
  • Page 103 ® Series 2600 System SourceMeter Instruments User’s Manual Appendix B: Frequently Asked Questions Figure B-3 Stacking channels for higher voltage NOTE Each stacked channel adds approximately 100μA of common mode current that is seen by the channels below it. Therefore, in the example above, Model 2602-1 Chan A will measure approximately 100μA x 3 = 300μA higher than Model 2602-2 Chan B.

    1. All Model 2611/2612s manufactured by Keithley Instruments support the contact check function. Only Model 2601/2602s with firmware revision 1.1.0 or later and SMU hardware revision E or later support the contact check function. To determine the firmware and SMU hardware revisions, inspect the data returned by the print(localnode.info()) command.

    ® Appendix B: Frequently Asked Questions Series 2600 System SourceMeter Instruments User’s Manual How do I make low-current measurements? Reference See Section 3 for more connection information, and Section 12 of the Series 2600 Reference Manual for command details. Low-current connections Low-current measurements (<1μA) are subject to errors caused by leakage currents and leakage resistances in the signal path For that reason, Model 2635 and 2636 SourceMeters are equipped with triax connectors to minimize these problems.
