Performance Verification Tests
Use the following performance verification tests to verify the measurement
performance of the U1211A, U1212A, and U1213A clamp meter. These
performance verification tests are based on the specifications listed in the
instrument data sheet.
These performance verification tests are recommended as acceptance tests
when you first receive the instrument. After acceptance, you should repeat
the performance verification tests at every calibration interval (to be
performed before calibration to identify which measurement functions and
ranges require calibration).
If any or all of the parameters fail the performance verification, then
adjustment or repair is required.
Carry out the performance verification tests according to
page 91 and

and range does not require adjustment (calibration). Otherwise,
adjustment is necessary.
When performing verification tests on current function, use Fluke
5500A/COIL with Fluke 5520A. Refer to
recommended test equipment information.
