1. 90-day specifications show full-range accuracy of recommended model used for specified
measurement point.
2. Resistor used to test Model 2601/2602 3A range and Model 2611/2612 1.5A range only should be
characterized to uncertainty shown using resistance function of digital multimeter before use.

Verification limits
The verification limits stated in this section have been calculated using only the
Series 2600 one-year accuracy specifications, and they do not include test
equipment uncertainty. If a particular measurement falls outside the allowable
range, recalculate new limits based both on the Series 2600 specifications and
corresponding test equipment specifications.
