STANDARD FEATURES

Case
SKP 4000 case has a handle for convenient movement and a compartment for safe transportation of the optical lens. It was designed for being frequently moved, e.g. between rooms or to the premises of the third part. The firm metal lids are quickly opened using clamp fasteners.
SKB 4000 is a benchtop version more adapted for work within one place. It has a protective cover which could be closed and locked at the end of work to keep the device safe from environmental impact.

Cutting & grinding module
This module consists of a cutting wheel, grinding wheel and a transport carriage.
To start the process operator places a sample into a sample holder and a sample holder into the carriage. As soon as a protective cover is closed, the discs could be launched. Carriage is moved between the discs with a lever and its proximity to the disk is adjusted with a feed screw.
The cutting and grinding module rotational speed can be separately regulated from 5 000 to 20 000 rpm.

Innovative sample holder
Brand new holder by SM Contact has interchangeable jaws adapted to corresponding connection.
Its shape precisely follows the shape of a sample, while special stop block fixes the sample at the same horizontal axial position. As a result perpendicular sample position and proper cut guarantee valid measurement results.

Etching module
Etching is necessary to make relevant details of a cross-section more visible. The current is applied to the sample holder and a felt pen dipped in electrolyte is used as a cathode.
Stable position of a sample holder is assured by the special receptacle and the etching time is limited with an adjustable timer for reasons of energy saving and safety.

Imaging
Prepared sample is located under the microscope to capture the image to be measured. Zoom lens with USB camera transfers the image to the standalone PC (SKP 4000) or to the built-in tablet (SKB 4000). Adjustable ring LED light provides good visibility.

Viso 6.00 measurement software
Captured image is measured with a help of special software – Viso 6.00. Operator chooses the parameters to measure, its reference values and performs the measurement on a cross-section image: measurements with appropriate presets or comparison to the Control list.
It also provides dimensions detection and data export to PDF format.

Supply kit
All the necessary spare parts and consumables are included into supply kit: abrasive papers, cutting disks, etching pen inserts, electrolyte, crossline reticle, etc. It is also available on stock on tooling.smcontact.eu

STANDARD FEATURES

Extra-long displacement path
Thanks to well-thought-out system (motor, guides, etc.) EPT 1000 allows displacement up to 157 mm. It makes the device applicable to large connections.

Changeable force sensor
Pull-force sensor is selected according to customers demand. Thus measurement range and accuracy can vary.

Ergonomic clamp arrangement
As a sample holder, a clamp or adapter with 12 slots of various widths are installed for wires of appropriate diameter. Therefore, the device can be used for almost all required cable processing tests (IEC 60352-2).
Sample positioning is as easy as ABC: operator pushes the lever and place the sample, as soon as the lever is released the spring system automatically pulls the clamp back. No need for a wrench or other special tools.

Measurement
Measurement is done automatically in the selected mode. It is also possible to move the carriage manually if necessary. Results are visualized in real time in the form of force-time curve graphics. Measurement modes:

  • Break (destructive) – the sample is pulled to break. The break point is determined by 25% of the applied maximum force.
  • Hold – the sample is not destroyed during this test. It is subjected to a defined force Fh. The applied force is held for a defined time Th.
  • Hold & Break – two previous modes are combined (hold and pull off). First, the hold mode is applied. Its duration is equal to time Th. Then the wire is subjected to a breaking pull force.

Measurement archive
All measurements results are saved even if the test is aborted: selected mode, force-time curve graphics, crimp width and height, maximum force, and hold duration of maximum pull-force (in Hold and Hold & Break modes).

User-friendly touch screen interface
65536-colour touch screen displays current measurement features, its settings and measurement archive. Settings menu allows to choose a mode, its parameters and carriage options, to select speed, interface language and measurement unit, as well as to start calibration of the device.
Intuitive navigation simplifies operation and enables reproducible test results.

Viso 6.00 is PC measurement software that helps to evaluate splice quality control by means of micro-section analysis and to maintain timely direct interaction with SM Contact engineering staff.
All the measurements are taken according to predetermined industry (VW, PSA, etc.) or customized reference values. Interaction between user and supporting engineers is performed through SM Cloud data storage and is an essential part of Full Process Control (FPC) Solution system.
If connected to the Internet, Viso 6.00 is updated automatically as soon as new updated appears.

This intuitive software guides the operator during the following operations:

  1. Operator prepares the sample with a help of laboratory equipment, capture its image and transfer it to Viso.
  2. Opening the operating panel of a software, operator chooses the mode: free measurement or Control list correlation.
  3. Selecting the free mode, operator chooses the parametres to measure. In the Control list mode the parametres and its reference values are predetermined.
  4. Operator measures the parameters by setting the start and end points of each measurement in the working area.
  5. Viso 6.00 generates a report (free measurement) or a comparison report (Control list mode).

STANDARD FEATURES

Control list with reference values
Optimal dimensions and its’ tolerances found in Control lists are determined by SM Contact for the corresponding connection on the step of qualification laboratory tests and FEA simulation (cross-view, pull-force, electrical resistance, galvanic corrosion, CPK match, etc.).
If connected to the Internet, Viso 6.00 automatically downloads all the new Control lists corresponding to the certain customer. Relevant documents are identified by the unique license number that is given to each user.

Conformity to individual and industrial standards
Viso 6.00 has 5 pre-stored sets of parameters (presets) which are to be examined during free measurement. There is one preset provided for all the possible parameters measurement and several more corresponding to the most useful industry standards (VW 60330, USCAR 21, TYCO114-18022-10, PSA 9634115099, Renault 36-05-019, SM Contact Norm).

Automatic measurement of splice dimensions and cross section area
It is possible to launch automatic size recognition of the following 5 parameters: crimp height; crimp width; support angle; inner terminal surface; final cross sectional area.

Simple-to-use program with guided procedure

Options

Full Process Control (FPC) Solution
If user’s service agreement includes FPC Solution the following quality monitoring and maintenance options are provided along with Viso 6.00 software:

  • Initial connection qualification and tooling definition (Control list forming);
  • SM Cloud data storage with private customers’ access keeping all connections’ information and its update (including Control lists, manuals and CPK reports);
  • Automatic notification of the supporting engineers in case of values deviation;
  • Annual re-validation of customer’s connections with updating of the Control list and drawing up recommendations for meeting the quality requirements.

CrimpiX achieves measurement accuracy thanks to quick-change clincher which follows the shape of a sample.
Operator lifts spring-loaded pin by pushing the lever. Then pin goes down to the sample and measurement is performed. Measurement results are saved on SD card or can be transferred to PC by Bluetooth.
Spring-loaded pin provides sufficient pressure to measure the sample, but doesn‘t deform it, unlike calipers or some micrometers. Enlarged view of work area is displayed on the screen for visuar control of measurement.

Technical characteristics

Measuring range: 0 – 12.7 mm
Accuracy: 0.005 mm (0.001 mm upon demand)
Power supply: 5 W max
Data transmission: Bluetooth, SD-card
Screen size: 320 x 240 px/3,5″
Image resolution: 640 x 480 px
Weight: 2.5 kg
Dimensions (W x D x H): 250 x 275 x 275 mm

ADVANTAGES

CrimpiX vs caliper
The jaws of a caliper doesn‘t fit the shape of a crimp. As a result it cannot always get to the bottom of a crimp or the sample can turn. In both cases obtained height values will be wrong. Another reason of improper measurement results is overcompression of the sample.

CrimpiX
CrimpiX guarantees proper positioning and correct measurement values thanks to a customized design of a clincher – it follows the shape of a crimp. Overcompression is impossible due to spring-loaded pin – it brings pressure sufficient for measurement, but without a risk of sample deformation.

CrimpiX vs micrometer
Due to the shapes mismatch within micrometer measurement crimp may be positioned between the anvil and the pin randomly, both in the longitudinal and in transverse planes. Thus, the accuracy of measurement depends on the skills of operator.

CrimpiX for standard crimp

For standard crimp height measurement CrimpiX is used with flat plateau clincher. Accuracy is provided by built-in camera: it fixes sample positioning, simplifying detection of the operator’s error.

STANDARD FEATURES

Clincher
Clincher follows the shape of a sample, which excludes the risk of improper positioning of a sample and false results. Сlincher is quick-changeable and it allows to measure different connections with one device.

Camera
Built-in camera displays enlarged view of the work area facilitating the operator‘s work. Captured images and measurements are saved on SD card or can be transferred to PC by Bluetooth.

Spring-loaded measuring pin
Spring-loaded measuring pin provides sufficient pressure to measure the sample, but doesn‘t deform it.

Extensive assessment of the quality
CrimpiX can be synchronized with Viso software: measurement results will be automatically added to Viso report on connection comprehensive quality check.
