WARNING
When connecting to the model 2611A, 2612A, 2635A, and 2636A
SMU outputs, with cables not rated for voltages above 42V, such as
the 2600A-ALG-2, you must disable the high voltage output by
using the INTERLOCK function as defined in
of this
manual. Leaving the high voltage enabled while not properly
insulating the external connections to the unit poses a shock
hazard which could cause serious injury to the user. It is also
recommended that the LO connection terminal not be allowed to
float by connecting it to signal ground or another known signal
reference.
Sensing methods
Source-measure operations are performed using either 2-wire local sense connections or 4-wire
remote sense connections.
NOTE The default sense setting is 2-wire local. See
later in this section to check and or change the sense mode.
2-wire local sensing
Two-wire local sensing (as shown in
) can be used for the following source-measure
conditions:
•
Sourcing and measuring current.
•
Sourcing and/or measuring voltage in high impedance (>1k
Ω
) test circuits.
