    • Reference Value
    • Reference Unit
    • Calibration Time
    • Minimum calibration time
      • Minimum calibration time should be set to safeguard so that the following two requirements are fulfilled:
        • 1 The hydrogen from the reference leak or gas line must reach the sensor before end of calibration time.
        • 2 The sensor must have time to reach its maximum signal before end of calibration time.
      • Setting Min Calibration Time too low will have the following effects:
      • Setting a high Min Calibration Time will have the following effects:
    • Password protected calibration
  • 8.5 Detection Mode Settings
