Variable Data Collect (VDC) allows operators to record Critical To Quality characteristics such as lengths, diameters, temperatures, voltage and weight.
You can set control limits to alert operators as soon as they enter measurements that show the system is out of control, allowing them to take the appropriate countermeasures. Inspect uses Nelson rules to decide whether a system is in control or not.
Data can then be viewed in statistical process control charts for real-time analysis.
VDC uses touch-screen technology to input data. On a handheld device the operator can touch the screen to enter data. If using a stationary PC with touch screen capability, the operator can either touch the screen or use a mouse to enter data.
In order to correctly use VDC there are a few steps that must be carried out in other programs before and after:
1. Form Composer: Create the required forms that will be presented to the operator (see here).
2. Cockpit: Setup a station to work with Variable Data Collect (see here).
Variable Data Collect can then be used as follows:
3. Login to your VDC station.
4. Select the data you wish to record.
5. Enter the observed values.
Once the VDC actions have been performed the results can be reviewed:
6. Advanced Reporting: Generate reports for review.
