This document contains specifications and supplemental information for the Models 2601B, 2602B and

2604B System SourceMeter®instrument. Specifications are the standards against which the Models

2601B, 2602B and 2604B are tested. Upon leaving the factory, the Models 2601B, 2602B and 2604B meet

these specifications. Supplemental and typical values are nonwarranted, apply at 23 °C, and are provided

solely as useful information.

Source and measurement accuracies are specified at the Models 2601B, 2602B and 2604B terminals

under these conditions:

1. 23 °C ± 5 °C, < 70 percent relative humidity

2. After a two-hour warm-up period

3. Speed normal (1 NPLC)

4. A/D autozero enabled

5. Remote sense operation or properly zeroed local operation

6. Calibration period: One year
