1. SPECIFICATION CONDITIONS
This document contains specifications and supplemental information for the Models 2635 and 2636 System
®
SourceMeters . Specifications are the standards against which the Models 2635 and 2636 are tested. Upon
leaving the factory the 2635 and 2636 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 SourceMeters
®
SourceMeters B (2636) 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 operation.
6. Calibration period: one year.
