- Modes of operation
- Operator mode: This mode is used by an operator performing routine
automated testing. Options available in Operator mode are limited to those
designed into the test by the engineer.
- Engineer mode: This mode is used by quality assurance and engineering
personnel who design and supervise the individual measurements and tests
that make up overall product testing.
Pass/Fail limits
Pass/Fail limits can be created in various ways:
- Setting an envelope in a specified range above and below a referenced
loudspeaker
- Statistical analysis of the measurements of a batch of loudspeakers
- Using the cursor to draw any arbitrary limits
Once a pass/fail limit is created, it can be modified manually by the
use of a cursor. |
