  • Page 67: Calibration

    CALIBRATION The instrument has been calibrated for a particular flammable gas mixture. Where any doubt exists the instrument should be returned to Teledyne GMI or an authorised distributor for calibration. Four methods of calibration are possible: • Automatic Calibration. The GMI Gas Delivery Unit (GDUnet) allows full automatic calibration.

  • Page 68: Calibration Validity

    12 month period can be expected. This is no guarantee, however, as the precise application of the product is unknown to Teledyne GMI. Individual codes of practice may dictate shorter periods. Regular checking establishes a pattern of reliability and enables the calibration check period to be modified in line with operational experience.
