Compliance limit

When sourcing voltage, the SourceMeter can be set to limit current. Conversely, when sourcing
current, the SourceMeter can be set to limit voltage. The SourceMeter output will not exceed the
compliance limit. The maximum compliance limit is the same as the maximum values listed in
Table 4-2. Note that the compliance value will take the same sign as the source value, and the
maximum compliance limits are based on source range. See
more information.
NOTE The only exception to the compliance limit not being exceeded is the

VLIMIT when operating as an ISOURCE. To avoid excessive (and
potentially destructive) currents from flowing, the VLIMIT will source
or sink up to 102mA for ISOURCE ranges on or below 100mA. For
the ranges 1A and above, the maximum current allowed is the
current source setting.
