Performance Verification Tests

The performance verification test is recommended as acceptance tests

when you first received the instrument. The acceptance test results should

be compared against the one- year test limits. After acceptance, you should

repeat the performance verification tests at every calibration interval.

If the instrument fails performance verification, adjustment or repair is

required. Contact your local Agilent Service Center for details.

This test checks the full- scale reading accuracy of the instrument.
