Compliance limit
When sourcing voltage, the Keithley Instruments Series 2600A System SourceMeter
®
instrument
can be set to limit current. Conversely, when sourcing current, the SourceMeter instrument can be
set to limit voltage. The Series 2600A output does not exceed the compliance limit, except for the
compliance limit conditions described in
.
Maximum compliance
The maximum compliance values for the source ranges are summarized in
.
Compliance principles
Compliance acts as a clamp. If the output reaches the compliance value, the SourceMeter
instrument attempts to prevent the output from exceeding that value. This action implies that the
