Performance Verification Tests
Fluke recommends re-certification each year. To re-certify, do the verification procedure.
If test points are out of tolerance, calibrate the Product and then re-verify. Two-year
specifications are included if the highest accuracy is not necessary.
Use the subsequent tests to make sure that the Product is inside its specification limits.
Verification Equipment
The equipment necessary for verification of the Product is shown in Table 2. If these
instruments are not available, you can replace them with other source and measure
instruments that have the same the minimum specification requirements.
