  • Page 94 If any sensor fails, recalibrate the Impact before using or alternatively replace the cartridge. Please refer to the Impact User Manual on general instructions on how to calibrate. Apply calibration span gas at a rate of 300ml/min for a period of 1 minute before starting the span calibration on the sensor.
  • Page 95 ISSUE 08 - 02/04 2302M5030 8. ROUTINE SERVICING The sensors fitted to Impact may give responses to gases other then the target gas. The table below gives typical sensor responses to various gases and should be used as a guide only. Note: Always use the target gas to perform sensor calibrations.
