1. SPECIFICATION CONDITIONS
This document contains specifications and supplemental information for the Keithley Instruments Models 2611 and
2612 System SourceMeters
Upon leaving the factory, the Models 2611 and 2612 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 (Models 2611 and 2612)
or SourceMeter CHANNEL B (Model 2612) terminals under the following conditions:
1. 23°C ± 5°C, <70% relative humidity.
2. After two-hour warm-up.
3. Speed normal (1 NPLC).
4. A/D auto-zero enabled.
5. Remote sense operation or properly zeroed local sense operation.
6. Calibration period: one year.

Temperature coefficient (0°C–18°C and 28°C–50°C): ±(0.15 × accuracy specification)/°C.
Maximum output power and source/sink limits:
±101mA, four quadrant source or sink operation.
Voltage regulation: Line: 0.01% of range. Load: ±(0.01% of range + 100 V).
Noise 10Hz–20MHz: <5mV RMS typical, 20V range, 1A limit.
Current limit/compliance:
Accuracy same as current source.
Overshoot: <±(0.1% + 10mV) typical (step size = 10% to 90% of range, resistive load, maximum current
limit/compliance).
Guard offset voltage: <4mV (current 10mA).
1 Add 50 V 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.
Specifications are subject to change without notice.
