Check the box in the “Select” column of the multiline to select the calibration schedules for which calibration orders must be generated.
Click the “Generate CO” pushbutton to generate calibration orders for carrying out the selected calibration schedules.
The system does the following:
It generates the calibration orders for the calibration schedules.
If the “Generate Work Order?” field is set as “Yes” in the “Create Calibration Schedule” activity, the system also generates work orders based on the calibration schedule.
Refer to the following section if you wish to know the working of the system while generating calibration orders for the calibration schedules.
Assumption: The current date is 03/31/2002 and calibration orders are generated till the 04/30/2002.

Example |
Result |
|
Extended Date – Not Entered Adjust Next Due Date – Not Applicable Interval Type – Fixed |
Interval – 10 days Initial Date – 4/11/2002 Interval Type – Fixed |
Calibration Orders would be generated for 4/11/2002 and 4/21/2002. |
|
Extended Date – Not Entered Adjust Next Due Date – Not Applicable Interval Type – Actual |
Interval – 10 days Initial Date – 4/11/2002 Interval Type – Actual |
Calibration Orders would be generated for 4/11/2002. Subsequent calibration orders would be generated based on the completion of the calibration order generated on 4/11/2002. |
Note: If the last calibration order were completed on 04/13/2002, then the next calibration order would be generated for 04/23/2002 (Completion Date + Interval).
If the last calibration order is not completed even after the lapse of one interval period, the next calibration order will be generated based on the last calibration order generation date.
Note: If the Interval Type is “Actual”, the next due date is computed and updated only on the completion of the last calibration order.

Note: If the previous calibration order is completed on 04/07/2002, the next calibration order will be generated for 04/17/2002. If the next calibration order is not completed even after the lapse of one interval period, the next calibration order will be generated for 04/15/2002 (Extended Date + Interval).
Usage-based Interval Schedule
The manner in which the system calculates the calibration orders that are due on the equipment is explained below with the help of an example:
|
Daily run hours of equipment |
10 hours |
|
Hourly usage of the parameter |
50 km |
|
Daily usage is calculated as Daily run hours * Hourly usage of the parameter |
500 km per day |
|
Present value of the parameter as on 03/31/2002 |
5000 km |
|
Interval for calibration |
2000 km |
|
Parameter value at which calibration is first due |
6000 km |
The first calibration order will be raised at 6000 km and the date on which the calibration order is raised is calculated as follows:
(Next Due Value – Present Value)/ Daily Usage
Applying the example we get,
(6000 – 5000)/500 = 2 days
The first calibration order is raised on 03/31/2002 + 2 Days = 04/02/2002.
Subsequent calibration orders will be raised on the equipment based on the date of completion of the previous calibration order. Assuming that the calibration order raised on 04/02/2002 was completed on 04/04/2002 and the parameter value as on 04/04/2002 is 6200 km. The next due value at which calibration must be carried out is 6200 + 2000 = 8200 km. The date on which the next calibration order is raised is calculated as follows:
(8200 – 6200) / 500 = 4 days.
The next calibration order will be raised on 04/04/2002 + 4 Days = 04/08/2002
|
Case |
Example |
Result |
|
Extended Value – Not Entered Adjust Next Due Value – Not Applicable |
Initial Value – 1000 km Interval Value – 2000 km |
Calibration orders would be generated for 1000 km. |
|
Extended Value – Entered Adjust Next Due Value – No |
Initial Value – 1000 km Extended Value – 1200 km Interval Value – 2000 km |
Calibration order would be generated for 1200 km. |
Note: When the next calibration order generation process is run, the system checks if the previous calibration order is completed within one interval range. If it is completed at say 1600 km, the next calibration order would be generated for 3600 km (1600 km + Interval). If it is not completed, the system generates the next calibration order for 3000 km (Initial Value + Interval Value).
|
Extended Value – Entered Adjust Next Due Value – Yes |
Interval Value – 1000 km Extended Value – 1200 km Interval Value – 2000 km |
Calibration order would be generated for 1200 km. |
Note: When the next calibration order generation process is run, the system checks if the previous calibration order is completed within one interval range. If it is completed at say, 1600 km, the system generates the next calibration order for 3600 km (1600 km + Interval). If it is not completed, the system generates the next calibration order for 3200 km (Extended Value + Interval Value).
Execution option for the generation of calibration orders
The number of calibration orders that are generated for calibration depend on the option that the user has selected in the “Interval Schedules” page in the “Create Calibration Schedule” and “Edit Calibration Schedule” activities.
Calendar and Usage Schedule independently
If you have selected this option one calibration order for every schedule is generated.
Calendar or Usage Schedule whichever is earlier
If you have selected this option, only one calibration order is generated for either of the calendar-based or usage-based schedules whichever is earlier.
Calendar and whichever earlier in Usage
If you have selected this option, one calibration order for the calendar-based schedule and one calibration order for the earliest of the usage-based schedules are generated.
Calendar-based fixed schedules
In this schedule one calibration order is generated for every date that is mentioned in the fixed schedule. For example, if you have specified the dates on which calibration must be carried out as 04/01/2002, 04/13/2002, 04/22/2002 and 04/30/2002, four calibration orders will be raised for all the specified dates.
Usage-based fixed schedule
In this schedule one calibration order is generated for every parameter value that is specified. For example, if you have specified the values at which calibration must be carried out as 2000 km, 5000 km, 7000 km, three calibration orders will be raised when the parameter reaches the three values.
Off-Seasonal Calibration
Calibration orders are not generated for the period that is defined as the Off-Seasonal. A period can be a date range or a range of specific days of a month, which will be recurring in nature. For example, if off-season for a calibration schedule is defined from July 10 2001 to September 9 2001, then calibration schedule would not generate the calibration order between July 10 2001 and September 9 2001. Off-Season can be defined as from April 1 to May 31also as annual recurring, then the calibration schedule would not generate the calibration order between April 1 and May 31 every year.
Calibration Order generation option
Calibration orders are generated after taking into consideration the calibration order generation option in the “Option Settings” activity. The system considers the option only if the following condition is satisfied:
If there is more than one calibration schedule and the following are similar for all the calibration schedules:
the equipment on which calibration must be performed
the work group that is responsible for carrying out the calibration
the next due dates of all the calibration schedules
Then, the system generates calibration orders based on the following:
If you have selected the option: “Combine Similar Tasks/SPs in One CO”, the system combines all the same tasks and creates one calibration order for the same. Separate calibration orders are created for each procedure that belongs to the calibration.
If you have selected the option: “Combine All Tasks/SPs in One CO” the system combines al the tasks in all the calibration schedules and creates one calibration order for the same.
If you have selected the option: ”All Tasks/SPs in Separate COs”, the system creates calibration orders for every task and for every procedure in all the calibration schedules.
