SPECIFICATION CONDITIONS
This document contains specifications and supplemental information for the Models 2601 and 2602.
Specifications are the standards against which the Models 2601 and 2602 are tested. Upon leaving the
factory the 2601 and 2602 meet these specifications. Supplemental and typical values are non-
warranted, apply at 23°C, and are provided solely as useful information.
The source and measurement accuracies are specified at the SourceMeter CHANNEL A (2601 and
2602) or SourceMeter CHANNEL B (2602) terminals under the following conditions:
1. 23°C ± 5°C, <70% relative humidity.
2. After 2 hour warm-up.
3. Speed normal (1 NPLC).
4. A/D auto-zero enabled.
5. Remote sense operation or properly zeroed local operation.
6. Calibration period = 1 year.

NOTES
1. Add 50µV to source accuracy specifications per volt of HI lead drop.
2. Full power source operation regardless of load to 30°C ambient. Above 30°C and/or power sink operation, refer to
Section 8 – Operating Boundaries in the Series 2600 Reference Manual for additional power derating information.
3. For sink mode operation (quadrants II and IV), add 12% of limit range and ±0.02% of limit setting to corresponding
current limit accuracy specifications. For 1A range add an additional 40mA of uncertainty.
4. For sink mode operation (quadrants II and IV), add 10% of compliance range and ±0.02% of limit setting to corre-
sponding voltage source specification. For 100mV range add an additional 60mV of uncertainty.
5. Add 150µs when measuring on the 1A range.
