Compliance considerations
Compliance limits
When sourcing voltage, you can set the SourceMeter to limit current from 10nA to 3.15A.
Conversely, when sourcing current, you can set the SourceMeter to limit voltage from 0.2mV
to 105V. The SourceMeter output will not exceed the programmed compliance limit.
Types of compliance
There are two types of compliance that can occur: “real” and “range.” Depending on which
value is lower, the output will clamp at either the displayed compliance setting (“real”) or at the
maximum measurement range reading (“range”).
The “real” compliance condition can occur when the compliance setting is less than the high-
est possible reading of the measurement range. When in compliance, the source output clamps
at the displayed compliance value. For example, if the compliance voltage is set to 1V and the
measurement range is 2V, the output voltage will clamp (limit) at 1V.
“Range” compliance can occur when the compliance setting is higher than the possible read-
ing of the selected measurement range. When in compliance, the source output clamps at the
maximum measurement range reading (not the compliance value). For example, if the compli-
ance voltage is set to 1V and the measurement range is 200mV, the output voltage will clamp
(limit) at 210mV.
Maximum compliance values
The maximum compliance values for the measurement ranges are summarized in Table 1-2.
