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
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
5
For sink mode operation (quadrants II and IV), add 10% of compliance range and ±0.02% of limit setting to corresponding voltage source
specification. For 200mV range add an additional 120mV of uncertainty.
Specifications are subject to change without notice.
