The Quality Control software extension for CLIO is a powerful suite for executing state of the art production line testing.
CLIO QC implements all the measurement techniques found in the CLIO standard software adding a versatile script processor that handles the test sequence most appropriate for your needs.
CLIO QC is able to test the production of loudspeakers, drivers, microphones, amplifiers and any other electroacoustic device.
CLIO QC can interact with external hardware or production line controllers in addition to PC peripherals, computer networks or with custom written software to implement a fully automatic test line.
CLIO QC can be configured to act as a measurement server. It is possible to easily integrate the sophisticated QC measurement techniques of CLIO inside custom written applications. Interaction takes place with TCP/IP trasfer protocol giving the possibility of remote control over a network.

FEATURES OF CLIO QC

CLIO QC is exceptionally powerful as it relies on the power of CLIO.
Here is a list of the parameters that can be calculated within each measurement:

Sinusoidal

- Frequency response and impedance reponse (mono or stereo tests)
- Average (or single frequency) level
- Sensitivity (average or up to eight frequencies)
- Polarity
- Total harmonic distortion response
- Single harmonic response (from 2nd to 10th)
- Fast-Track Rub&Buzz response
- T&S parameters (Fs,Qt,Qe,Qm,Cms,Mms,Mmd,Vas,Bl,dBSPL,ZMin)
- Loudness Rating (RLR, SLR, STMR)

MLS&CHIRP

- Frequency response or impedance response (mono tests)
- Average (or single frequency) level
- Sensitivity (average or up to eight frequencies)
- Polarity
- T&S parameters (Fs,Qt,Qe,Qm,Cms,Mms,Mmd,Vas,Bl,dBSPL,ZMin)
- Loudness Rating (RLR, SLR, STMR)

FFT

- Frequency response with definable stimulus (mono tests, also interactive)
- Average (or single frequency) level
- Sensitivity (average or up to eight frequencies)

METER
- SPL, Volts, THD, IMD single parameter (mono tests, also interactive)

The QC processor is able of handling a virtually unlimited sequence of tests to accomplish even the most complex tasks; on the other hand a single ultra-fast sinusoidal test (read about it in 20.1) may ensure you production cycle times of less than 1 second with total integration with the line controller.

Some of the QC management features are better explained starting from the various people taking part in this complex operation and their points of view:
- The operator working on the line
- The quality control engineer responsible for production line operation
- The company and its managers controlling the overall process

All QC operations can be password protected; file operation can be restricted by their digital signature.

THE OPERATOR'S POINT OF VIEW
A quality control test can be controlled by simple Go-NoGo masks letting even the least experienced operator work without problems and with no learning curve.

A more complex operation foresees the continuous display of the measurements executed until the reaching of the final result.

A third possibility is to view and interact with the test sequence during its execution.

Completed test information and reports are always presented to the user.

THE ENGINEER'S POINT OF VIEW
As the QC is integrated inside the CLIO software no new user interface has to be learned by the engineer who has experience of CLIO inside her or his research laboratory. A quality control test relies on real measurements saved on disk and on a simple text script.

Defining a QC script is easy as it requires the writing only a few descriptive lines of text, no programming languages or complex instructions are involved.

It is possible to capture the active measurement; the check masks can also be input in a visual manner drawing limits over the measurement; debugging is helped by an internal corrector.

THE COMPANY'S POINT OF VIEW
CLIO when used for quality control executes line testing in a fast, accurate and reliable manner. Its flexibility permits easy handling of trade-offs between parameters like speed and accuracy always matching the companys’ needs. The autosaving and exporting capabilities together the complete result reporting gives instant access to the production parameters and statistics even during its operation. The production batch is fully managed while preserving serial number coherence.
