  • Page 35: Calibration

    Two methods of calibration are possible: • The fully automatic, PS1 Auto Bump / Calibration Station (Part No. 63450), provides controlled delivery of gas, allowing you to calibrate in a controlled manner and maintain a record of calibration results on a PC.

  • Page 36: Calibration Validity

    This is no guarantee, however, as the precise application of the product is unknown to GMI. Individual codes of practice may dictate shorter periods. Regular checking, by using bump-test procedure, establishes a pattern of reliability and enables the calibration check period to be modified in line with operational experience.
