Preventive maintenance and calibration of miniature spectrometers to detect and control the gradual degradation of designed performance parameters. Miniature spectrometers have a higher probability of internal damage caused by extreme mechanical shock directly related to their portability and flexibility of use. It is required to be maintained to control drift in any measuring device, and calibrated to ensure reliable, accurate, and repetitive results. Preventive maintenance and calibration practices assure that the measurements and results will be comparable to those obtained by any other person or entity using similar equipment, maintained and calibrated with the same parameters and reference. Periodic preventive maintenance and calibration are investments that will add value to research, products, or services. Preventive maintenance assures that major changes in the instrument are brought back to the original design for proper performance.
