    Red: Replace batteries immediately. *The voltage in the battery will decrease when the GasClam is sampling due to a load on the batteries, this is the voltage that should be used to assess battery condition (This is also the voltage that is logged).
  • Page 15 After starting the GasClam through the software wait until the first cycle is complete. The last readings stored will be updated and these values can be used to check that the GasClam is functioning correctly. Also this will remind the user that the GasClam has been started before leaving it for a period of unmanned data collection.
