Maintenance and Calibration Service
Gibitre Instruments provides maintenance and calibration service for all instruments installed. Calibration is carried out by Gibitre using reference instruments with traceability to primary standards
Characteristics of the Service
• Gibitre Instruments provides maintenance and calibration services for all the instruments produced.
• The services offered have been studied and are continuously improved to meet the highest requirements of the customers regarding the reliability of the measures and the certificate formats.
• The service is coordinated directly from the Gibitre office for most European countries or is provided by a Gibitre agency through technicians directly trained and qualified by Gibitre.
Programmed Maintenance and Calibration Service
The service is offered in the form of an annual Maintenance Contract and includes:
• the cost for the maintenance and calibration of each Gibitre instrument owned by the customer
• the cost for the transfer of the technician that is evaluated based on the distance, the number of operations scheduled in the year and the estimated work time for the provision of the service
• activation of the Remote Assistance service for the duration of the maintenance contract (for instruments controlled via PC)
• optional software update services
The number of annual maintenance / calibration for each instrument and the timing of execution of the activities are defined according to customer needs.
The underwriters of a Maintenance Contract are entitled to discounted rates for any extra-contract repair activities and for the purchase of spare parts
Repair service
The repair service has been optimized in order to minimize the time to resolve malfunctions, to minimize repair costs and to provide the customer with complete and transparent information regarding timing and costs.
Repair interventions are carried out according to the following methods:
- A diagnosis of the problem is performed using the Remote Assistance Service
- An offer is formulated in which the estimated costs for the spare parts and the hourly cost for the intervention of the technician are quantified
- Upon receipt of the order, the activity of a technician is immediately scheduled
- The final cost for the activity is calculated after intervention according to the real time needed for the activity and the spare parts actually replaced.
Calibration of the instruments
The calibration of the instruments is carried out according to the requirements of the international reference standards.
The list of calibration operations that are performed for each type of instrument are specified in the offer of the Calibration Contract and are described in detail below.
The procedure for the performance and the reference instruments for the execution of each specific calibration phase are described in the Calibration Report.
The standard calibration procedure can be modified to meet specific customer requirements. Specific needs must be agreed when issuing the Calibration Contract.
Reference instruments used for the calibrations
• Gibitre Instruments owns a complete set of Reference Instruments for each type of instrument for which it provides calibration services.
• Reference Instrumsnts are directly calibrated by accredited laboratories and are stored in Gibitre Metrological room with controlled temperature and humidity conditions.
• Every technician authorized by Gibitre to perform the calibration has at his disposal a complete set of Reference Instruments and templates that allows to perform all the calibration operations required by the Gibitre procedures.
• Each instrument used by the technicians is subjected to periodic calibration. The identification label of the instrument identifies it unambiguously and returns the calibration date.
Traceability of the Calibration Instruments
• The Calibration Reports show the complete list of primary and secondary instruments used for the calibration and include the Hyperlink for downloading the relative Calibration Certificate from Gibitre website.
• The measurement uncertainty related to each calibration made is calculated considering the uncertanty of the instrument/s used, the dispersion of the results, the resolution of the instrument under calibration.
Habilitation of Gibitre technicians
Gibitre Instruments scrupulously follows the training of the technicians who carry out the calibrations through training and coaching activities with expert technicians.
The method used for the assignment of the calibration to the technicians includes the automatic verification of the technician's qualification for the execution of a specific activity.
The link in the Calibration Report permits to download from Gibitre web site the Report with the habilitattion of the technician who performed the calibration.
