Primary features: |
- Operator or
engineer mode |
- View detail of
each measurement |
- Smoothing of data
and pass/fail limits |
- Tracking by
serial number information |
- Output can be
ported to screen, disk or printer |
- Statistical
information on each model or batch |
- Password
protection for Engineer mode |
- Multiple methods
of establishing pass/fail limits |
|
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
microphone |
- Statistical
analysis of the measurements of a batch of microphones |
- 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. |
