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
“Functional tests (only for U1212A and U1213A)”
listed step:
1
Connect the calibration standard terminals to the input terminals on the clamp
meter.
2
Set up the calibration standard with the signals specified in the “Reference
signals/values” column (one setting at a time, if more than one setting is
listed).
3
Turn the rotary switch of the clamp meter to the function being test, and
choose the correct range, as speficied in the table.
4
Check whether the measured reading falls within the specified error limits from
the reference value. If it does, then this particular function and range does not
require adjustment (calibration). Otherwise, adjustment is necessary.
NOTE
When performing verification tests on current function, use Fluke 5500A/COIL
with Fluke 5520A. Refer to
86 for recommended test
equipment information.
