Work order tracking in calibration

When you create a work order, you initiate the maintenance process and create a historical record of work that is being performed.

You use the Work Order Tracking application to create and manage calibration work orders.

When you create a calibration work order, you specify the work order with one of the following work types:
  • CAL
  • PMCAL
  • CMCAL
  • EMCAL

You use data sheets that are associated with a work order to calibrate an asset. A data sheet contains the specifications of an asset that is required for the calibration of the asset.

The data sheet also records uncertainty measurement data for instruments and measurement and test equipment. When a data sheet is attached to a work order, the uncertainty measurement data is imported from the Data Sheet Template application. Alternatively, uncertainty measurement data can be entered or imported directly into the work order data sheet.

On calibration work orders, you can view the calibration history of an asset and check the status of a tool associated with a work order. You can also record the result of a spot check for a tool associated with a work order and review data sheets that are attached to work orders.

Work order data sheets

You use the work order data sheet to enter data that is gathered during the calibration of an asset. Calibration assets are instruments and measuring and test equipment (M&TE).

Data sheets are created in the Data Sheet Template application and associated with assets. When a work order is created for a work asset with one or more associated data sheets, the data sheets are copied to the work order. You can also associate data sheets with job plans or attach them directly to a work order.

Only approved data sheets can be processed on work orders. During the calibration of an asset, you can enter the results of the as-found and as-left data. This data is used to analyze asset performance and calibration frequency.

As-found and as-left data

As Found and As Left are standard industry terms. The As-found and As-left data determines the calibration status of the asset.

When an asset is calibrated, the As-found data is recorded. As-found data is the calibration results before the asset is adjusted. In Maximo® Calibration, the As-found values are calculated to ensure that they are within the established range that is specified on the data sheet. If the values are outside the limit range, the asset is adjusted and the As-left results are recorded. As-left data is the calibration results after the asset is adjusted.

You must complete all As-found and As-left values before you can close a work order.
