Performance Verification Test
The performance verification tests are recommended as acceptance tests
when you first receive the instrument. The acceptance test results should be
compared against the specifications given in chapter 1. After acceptance, you
should repeat the performance verification tests at every calibration interval.
If the instrument fails performance verification, adjustment or repair is required.
Adjustment is recommended at every calibration interval. If adjustment is not
made, you must guard band, using no more than 80% of the specifications
listed in chapter 1, as the verification limits.
