The Calibration add-on provides functionality to perform instrument calibration, calibration of instrument loops, and calibration of measurement and test equipment (M&TE). It is included as part of the Maximo for Nuclear industry solution.

The instruments to be calibrated are defined as assets, and instrument loops are defined as locations. The measuring devices and standards used as part of calibration are defined as rotating tool items, and each device of a particular tool item is defined as a tool asset, to provide traceability of the actual measuring device or standard used in the calibration. For specialist calibration equipment you can track the qualification required to use the device to ensure that the calibration technician has the appropriate qualifications when the work is performed.

Many calibrations will be performed on a periodic basis, either time based or meter based. These are set-up as Preventive Maintenance records with the job plan used to define the tasks and resources needed to perform the calibration. Tracking the user or custodian of the asset to be calibrated is a good idea as then notifications can be sent out to inform them of when calibration will be due and when calibration will expire on the asset to be calibrated. If there are multiple similar instruments that require calibration then a Master PM record can be used to create each individual PM.

Ad-hoc calibration requests can be made through a service request. A ticket template can be set-up to define the type of calibration needed and a service level agreement applied to automatically calculate a response and resolution time for the calibration request. The service request creates a calibration work order.

The Data Sheet Template application defines the calibration process. One or more asset functions are created with their input ranges and expected output ranges with the tolerances that determine limits of adjustment or failure. An asset function can have multiple calibration points that test the output at nominal input points in the range. Locations and assets are associated with the data sheet template. A job plan is associated with locations, assets and the data sheet templates to be used with them. When a work order is created or generated from a PM and a job plan is applied then the data sheet templates are automatically derived for the location or asset referenced on the work order. 

The calibration is performed in the Work Order Tracking application on the Data Sheet tab. The calibration technician records as found and as left readings, and statuses, as they proceed to calibrate the instrument according to the defined steps from the applied data sheet templates. They also record the actual devices and standards used in the calibration. The Maximo Anywhere Work Execution mobile application is used by calibration technicians performing calibration in situ.
