2.6

Calibration

Although somewhat contingent on the usage environment and how often the FRA5097 is used,
conduct the performance tests of Section 8.5 at least once a year. The performance tests are also
recommended immediately before using the equipment for important measurements or testing.
Refer the performance tests to technicians possessing experience in operating measuring
equipment and have a good general knowledge of instrumentation.
