Quick Performance Check
The quick performance check is a combination of internal self-test and an
abbreviated performance test (specified by the letter Q in the performance
verification tests). This test provides a simple method to achieve high confidence
in the instrument's ability to functionally operate and meet specifications. These
tests represent the absolute minimum set of performance checks recommended
following any service activity. Auditing the instrument’s performance for the quick
check points (designated by a Q) verifies performance for normal accuracy drift
mechanisms. This test does not check for abnormal component failures.
To perform the quick performance check, do the following:
1 Perform a complete self-test. A procedure is given on page 64.
2 Perform only the performance verification tests indicated with the
letter Q.
3 If the instrument fails the quick performance check, adjustment or repair is
required.
Performance Verification Tests
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.
Special Note:
Amplitude and Flatness Verification Procedures
Measurements made during the "AC Amplitude (high-impedance) Verification"
procedure (see page 69) are used as reference measurements in the flatness
verification procedures (beginning on page 71). Additional reference
measurements and calculated references are used in the flatness verification
procedures. Photo-copy and use the table on page 67 to record these reference
measurements and perform the calculations.
