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.

Page 173: Remote Triggering Overview
Series 2600A System SourceMeter® Instruments Reference Manual Section 10: Triggering Remote triggering overview There are two programming methods for triggering: • Using the trigger model. • Interactive triggering. Using the trigger model to control the actions of the SMU allows the user to obtain very precise timing and synchronization between SMUs of a single instrument or between channels of multiple instruments.
Page 174: Using The Remote Trigger Model
Section 10: Triggering Series 2600A System SourceMeter® Instruments Reference Manual Trigger events are identified by means of an event ID. Table 10-1 describes the trigger event IDs. Table 10-1 Event IDs Event ID Event description Occurs when the SMU transitions from idle state to smuX.trigger.SWEEPING_EVENT_ID arm layer of trigger mode.

Series 2600A System SourceMeter® Instruments Reference Manual Section 14: System Expansion (TSP-Link) Initialization Before a TSP-Link system can be used, it must be initialized. For initialization to succeed, each instrument in a TSP-Link system must be assigned a different node number. Assigning node numbers At the factory, each Series 2600A instrument is assigned as Node 1.

Series 2600A System SourceMeter® Instruments Reference Manual Section 14: System Expansion (TSP-Link) System behavior Using the reset () command While most TSP-Link operations target a single node in the system, the reset() command affects the system as a whole. The reset() command, by definition, resets all nodes to their default settings: -- Resets all nodes in a TSP-Link system.
