The SigMETER signature analysis capability delivers high performance and versatility for the most complex manufacturing test applications.  You will find powerful features and functions usually found only in specialized or larger, more expensive instruments. The technique of "signaturing" is to collect and analyze the entire test data waveform.   Mathematical features are extracted from the data and compared to "good" data which results in a pass/fail decision. This powerful SigMETER feature offers a whole new scope of test flexibility.  The benefits are numerous, including:
- Enhanced product quality through improved t4esting
- Root cause defect determination
- ZERO-DEFECT goal.

Leak Testing

With it's high precision internal clock, multiple analog inputs, and high output relays, the SigMETER is ideally suited for almost any leak testing application.  Added features like signature analysis and 16-bit A/D converter mean faster, more accurate leak rate determination.   Other SigMETER leak testing benefits are:

- temperature compensation (automatically compensates for any temperature change)

- multiple recipe/volume support for different product types

- calculates actual leak rate in true engineering units (e.g. cc/min)

- output relays of SigMETER can switch most solenoid valves, eliminating the need for external relays or logic controllers

-  ultra-precision internal timers can measure decay time with millisecond resolution

- "smart" functions like standard deviation and best-fit slope can reduce test times by making decisions sooner than standard mathematical functions

Press Fit Assembly

On-line testing of press fit operations is simple with the SigMETER.  It's high speed data collection (with customized triggering), and specialized press-specific signature analysis routines mean most of the work is already done for you.  Some more Specific benefits of the SigMETER in these applications are:

-  full force waveform collection and analysis

-  built-in signature routines like "cusp point" (bottom-out force) and "area" (work performed) automatically determine critical press information

-  high speed data collection (up to 10 kHz) will satisfy even the most demanding pressing or stamping operations

-  supports both time-based or distanced-based data collection

Torque-to-Turn

The SigMETER's integrated encoder support is a key element in providing an accurate torque-to-turn test system.  The ability to precisely pinpoint the value and location of anomalies in a torque waveform provide a source of invaluable data in both past-assembly and on-line testing.  Other benefits include:

-  high speed torque sampling based on time or encoder, combined with deterministic response to process events, make time-critical operations like fastening possible

-  signature analysis provides much more than standard peak detection (slopes, peak-to-peak, location of peaks, etc.)

-  can compare successive waveform signature results to aid in defect identification (e.g. repeatable peak and location indicates Defect A)

Gaging

With its ability to support several testing sequences in one unit, the SigMETER can be used to consolidate measurements, calculations and calibrations in almost any gaging application.  The SigMETER also supports:

-  full floating point math for highly accurate calculations

-  built-in support for "live" messaging, operator feedback, and sensor calibrations, making automated part "mastering" and/or calibrations simple

-  e.extensive mathematical and logical calculations, including full trigonometric support (SIN, COS,TAN, etc.)

Inspexion
Real Time Power for Test and Analysis

InspeXion provides real time signature analysis that takes advantage of continually increasing processor speeds to provide immediate results. A unique architecture runs data collection and analysis separately from the graphical interface for enhanced performance and security and can take advantage of dual processors for optimum performance. Interrupt driven events provide predictable timing for deterministic response InspeXion consists of three main parts: The Integrated Development Environment (IDE) for graphical application development; the Operator Interface for displaying information and providing user control; and the InspeXion Engine which manages the actual testing and signature analysis.

 

The InspeXion Engine works behind the scenes to provide core test functionality through a deterministic real-time kernel to handle inputs, outputs, events, and sequences as configured by EnspeXion IDE. With InspeXion MP (Multi Processer) software the Engine communicates with the Operator Interface, but can run independently on a separate processor under the Windows NT environment to provide optimal performance and security when needed. InspeXion IDE uses a graphical approach to make system configuration simple. Inputs and outputs are defined here as well as test sequences and events. Integrated data review and hardware diagnostics ensure that everything is setup correctly. InspeXion IDE can run independently of the test hardware so you can configure the system "off line" in the quiet of your office if desired. InspeXion Operator Interface provides graphical run time user interface and data management with displays and menus that you configure to your needs. Display objects are updated frequently and events can be controlled with menu buttons. Multi-level passwords are supported to provide the right level of access for different types of users.
