Performing accuracy verification
After calibration is completed, the Model 2110 should be verified to ensure that its performance is
within the manufacturer’s specifications.
Perform accuracy verifications using the Fluke 5700A/5725A and 5520A/5522A standards. Refer to
the following tables for accuracy limits for the specified ranges.
