Easy to use
Functionalities and Modules
Measuring Instrument Management Keep track of your measuring instruments

Manage your measuring instruments simply and effectively…

A powerful tool for any metrologist who wants a simple instrument management system, saving time using indicators and custom alerts

  • Choose indicators on the home page for a quick and easy analysis
  • Simplify job callouts and interactions with calibration providers
  • Identify any instruments that are nonconform or out of the tolerance range for effective decision-making
  • Follow progress and detect instrument drift

… for stress-free audits

  • Quick, easy management of measuring equipment
  • Compliance with ISO 9001, 10012, IATF 16949, 9100, 13485, 17025, 15189, …
  • Creation of delivery notes, shipping notes, and labels
  • Automatic mailing of indicators (late instruments, jobs to be scheduled, monthly / annual budgets, ...)
  • Input / output management and equipment reservations
  • Ensure traceability using bar codes
  • Exchange feedback with many other calibration laboratories

Simplify your calibrations operations

Optimu meets the needs of in-house and / or accredited laboratories (Cofrac in France, SCS in Switzerland and Accredia in Italy), who have chosen Optimu to:

  • Technical library: calculation of theoretical values ​​for gauges (reference standards, manufacturer, or added customer standard requirements)
  • Calibration of all types of instruments
  • Real-time declaration of conformity during calibration using reference standards, manufacturer or customer requirements
  • Automatic editing of calibration documents (CC / VC) with or without accreditation
  • Taking account of the uncertainty in the declaration of conformity (ISO 14253-1)
  • Traceability to measurement standards and taking account of corrections to the values provided by these measurement standards
  • Offline calibrations , performing calibration campaigns at customer sites in a simple and intuitive way

Choose the most suitable optimization method for your instruments

The optimization module is natively included in the software to allow industrials to use the calibration interval optimization methods described in the FD X07-014 booklet

  • Simplified application of the OPPERET method, to take account of the various influencing factors
  • Drift method used to anticipate the wear limit cut-off date based on calibration logs
  • Periodicity ratio method used to determine the best date for the next calibration, based on how much the instrument affects the uncertainty measurement process
