  • Page 29: Maintenance Requirements

    SUPPORT CENTER ADVISORY G. Maintenance Requirements 1. Bump Testing • A bump test exposes the gas detector to a gas. The operator then observes the gas detector’s response to the gas and it is mainly used to see if gas detector is reacting to the gas and to determine if all the detector’s outputs are working correctly.
  • Page 30: Gas Detector Response Adjustment

    SUPPORT CENTER ADVISORY c. Expose the gas detector to gas from the cylinder. Monitor the LED display reading and check the outputs functions. 2. Gas Detector Response Adjustment • Adjusting gas detector response exposes the gas detector to a calibration gas as well but additionally sets the actual gas detector response level to ensure that the gas detector activate on the specified gas concentration.
