# The Charts Tab (Measurement)

To view this tab, you must select at least one parameter by checking in the Chart field on the Readings tab. The number of charts displayed will be as per the number of parameters selected.

Online XbarR charts of the selected parameters are displayed. Details like part code, parameter code, Cpk value and Ppk value are shown. Readings are plotted along with date and time of readings. You can scroll through the charts.

The number of points displayed in the online chart depends on the value entered for display of online points in the Company Settings screen. For example, if the value entered is 20, the chart plots only the last 20 samples. If no value is entered, all samples are plotted.

The last customized trend message along with date and time for that parameter is displayed in a scrollable log window. You can scroll through the history of trends raised for that parameter.

For all Line Charts: To view details of all actual readings for the samples, use the mouse to move the cursor to the points plotted on the chart.

Double-Click on the chart to see the list of available charts for the parameter. Select the required chart you wish to view.

By default online chart for 100% inspection parameters will X-MR and for sampling parameters default chart displayed will be X Bar R chart. Facility to change online chart for a parameter will activated at right click on chart.

Pre Control Chart –

For parameter having pre control chart, Reading, Chart Tab will get enabled & Control Chart will get disable if all parameter having pre control chart then Cp/Cpk Tab will also get disable.

# Manual Mode –

Parameter having pre control chart display picture along with message during dumping a data.

Picture along with message will display only when after reading will get approved & there after i.e after 5 reading onwards. Picture along with message is depend upon the rule set for pre control chart.

# Automatic Mode –

Parameter having pre control chart display signal on acknowledge unit during dumping a data.

Signal will display only when after reading will get approved & there after i.e after 5 reading onwards. Signal (red/green) is depend upon the rule set for pre control chart

Display signal or picture for 1st 5 reading –

If all reading is within green zone then green picture along ‘Setting Approved’ message in case of manual mode & Green signal in case of automatic mode will get display.

One of the readings goes in Red zone then red picture along ‘Stop’ message in case of manual mode & Red signal in case of automatic mode will get display.

Only one of the readings goes in yellow zone then red picture along ‘Repeat Setting’ message in case of manual mode & Red signal in case of automatic mode will get display.

More than one readings goes in yellow zone then red picture along ‘Adjust’ message in case of manual mode & Red signal in case of automatic mode will get display

5th reading onwards –

In case of manual & automatic mode 2 consecutive reading to display signal or picture.

If one of reading is within the green zone then in case of Manual mode green picture along with the ‘Continue’ message will get display & in case of Automatic mode green signal will get display.

If one of reading is within the red zone then in case of Manual mode red picture along with the ‘Stop’ message will get display & in case of Automatic mode red signal will get display.

If both reading is within the yellow zone then in case of Manual mode red picture along with the ‘Adjust the process’ message will get display & in case of Automatic mode red signal will get display.

For a pre control chart parameter reading is approved. Reading Tab is active.In company setting, ‘No of point to display on online chart’ is 20 & user had 50 reading for pre control chart parameter. Pre Control chart will get refresh & redraw the chart i.e Last 20 readings i.e. 31 to 50 and additional 5 readings which nothing but approved setting reading. So the total reading on the chart is 25

# Sample Frequency –

# Screen should check that readings for parameter are taken as frequently as defined in Sample Frequency in Standard QAP. If readings are not taken within time and in company setting user checked Display/Capture Time to Take Reading then screen should notify that readings are not taken and its time to take reading. Notification will be different in manned and unmanned station. In case of manned station message will be displayed on screen. And in case of unmanned station message will be inserted in message table for all supervisor users. Supervisor user is one whose role is defined as "SUPER ". Sample frequency is made available for 100% inspection and sampling technique. Time to take reading message will not get display or recorded if check box of Display/Capture Time to Take Reading is not checked.

# Deletion of reading and Sample –

- While deleting the sample it will check for corrective action has been taken or not, if corrective action has been taken then it will display. "Corrective action has been taken. Do you want to delete the sample? " If the user clicks on No the sample is not deleted, if the user clicks on Yes the sample is deleted.

- While deleting the sample it will check for trends. If trend raised it will display. "Trends have been raised. Do you want to delete the sample? " If the user clicks on No the sample is not deleted, if the user clicks on Yes the sample is deleted.

In both cases i.e. in case of sample deletion or reading deletion when the reading no is zero for the parameter and the user clicks on F6 the user should not be allowed to delete a reading or a sample.

In case of Single Instrument multiple Parameter –

User selects the sample or reading and selects Delete Reading/Sample system will prompt the message "Are you sure Do you want to Delete reading only for the selected Parameter?"

With Yes or No

If user Press ‘Yes’ then record for selected parameter for selected Reading serial No. will get deleted and charts get refresh with updated Reading Serial No.

If user Press ‘No’ then system will prompt the message "Are you sure Do you want to delete reading for all parameter?" with Yes or No. If user press ‘Yes’ then record for all parameters for selected Reading Serial Number will get deleted and chart get refresh. If sample is completed then the user try to delete the reading then whole sample will get deleted. If sample is not completed then only specific reading will get deleted.

Job is of Single instrument multiple parameter having 3 parameters, Sample size is 3, First two parameter has taken 2 reading i.e. 2/3. Third Parameter has taken 1 reading i.e. 1/3. User tries to delete the reading of 3rd parameter. Message should display ‘Can not delete reading for the selected parameter as parameter is of Single Instrument and then delete operation will get cancelled.

Remarks –

If the online chart displayed is X Chart when the user right clicks on the reading no, it displays three menu options, add remark, view remark, delete reading/sample When the user clicks on add remarks, remarks for reading screen are displayed. User is allowed to enter the remarks and click on Ok, which will launch reading sample screen. If the user clicks on cancel it will still launch reading sample screen. If a remark is present then it will show the remarks for the selected reading else it will show the Reading Sample screen

Corrective Action –

When Sample has trend and user moves the mouse pointer on that sample then it should display the Corrective action as popup similar to Add Remark, view Remarks. If the User clicks on the corrective action menu it should display a separate screen showing the trends and their level and when the user clicks on the Ok button, the corrective action screen will be launched allowing the user to take corrective action. Once the user takes corrective action that samples color becomes blue and it is large and displays the vertical line.

If the color of the sample is blue then it means corrective action has been taken and if the user selects the sample the corrective action screen is displayed with the corrective action that are taken.

On-Line Chart Plotting –

Histogram will always display in decimal whether parameter UOM is angle or Not.

#### Trends

Trends are raised when sample size is greater than one and the average of the readings within the sample is out of limits. The last Customized Trend Message along with the date and time is displayed in a log window. You can scroll through this window to view the history of trends raised for the parameter.
