Series 2600A System SourceMeter® Instruments Reference Manual
Section 3: Basic Operation
A returned value of 1 indicates that the voltage limit has been reached if the unit is configured as a
current source, or that the current limit has been reached if the unit is configured as a voltage
source.
Basic circuit configurations
The fundamental source-measure configurations for the Series 2600A are shown in
.
When sourcing voltage, you can measure current or voltage (configuration A). When sourcing
current, you can measure voltage or current (configuration B). See
for more detailed information on these circuit configurations.

Operation considerations
The following paragraphs discuss the warm-up period and auto zero.
Warm-up
The Series 2600A must be turned on and allowed to warm up for at least two hours to achieve
rated accuracies.

Description
smuX.source.limiti = limit
smuX.source.limitv = limit
compliance = smuX.source.compliance
Set current compliance limit.
Set voltage compliance limit.
Test if in compliance (1 = in compliance;
0 = not in compliance).
*smuX = smua for the Model 2601A/2611A/2635A; smuX = smua (Channel A) or smub (Channel B) for the
Model 2602A/2612A/2636A.
