can use alternate equipment as long as that equipment has specifications equal to
or greater than those listed in the table. When possible, test equipment
specifications should be at least four times better than corresponding Series 2600
specifications.

1. 90-day specifications show full-range accuracy of recommended model used for specified
calibration point.
2. Resistor used to calibrate Model 2601/2602 3A and 10A ranges and Model 2611/2612 1.5A and
10A ranges should be characterized to uncertainty shown using resistance function of a digital
multimeter before use.
3. Used for contact check calibration. Characterize resistors using ohms function of digital
multimeter before use.
