  • GMP251 CO2 probe
  • Probe splitter M8/M12 (item code CBL211050)
  • DC power supply with micro-USB connector
  • Optional: any supported humidity or temperature probe
  • Optional: probe extension cable(s)
CAUTION

To support operation with a CO2 probe, the RFL100 data logger must have firmware version 1.4.0 or higher, and must be manufactured after July 2021. Additionally, make sure all AP10 access points at the location of use have firmware version 4.0.0.

External power supply is a requirement for operating the data logger with a CO2 probe. Batteries are used as a backup power source if the external power fails. Lithium batteries are recommended as they provide a longer backup time, but even with lithium batteries the operation time is limited in CO2 mode (typically at least 12 hours). The data logger will show the error code Err 106 if it operates in CO2 mode without a power supply.
  1. If any cable is connected to the service port of the data logger, disconnect it.
  2. Open the battery cover of the data logger.
  3. Make sure the power switch is in the Off position.
  4. Verify that the data logger has lithium batteries (type FR6) inserted. Replace the batteries if necessary.
  5. If the probe splitter M8/M12 is not yet connected to the data logger, connect it now:
    1. If a probe or cable is currently connected to the probe connector, pull it straight out without rotating it.
    2. Align the orientation mark on the probe splitter with the line above the probe connector. Push the probe splitter straight in all the way, do not rotate.
      You can also use a probe extension cable between the data logger and the probe splitter.
  6. Connect the CO2 probe to the M12 connector of the probe splitter, using a suitable extension cable if necessary.
  7. Optional: connect the temperature or humidity probe to the M8 connector of the probe splitter, using a suitable extension cable if necessary. If you do not connect a probe to the M8 connector, make sure the connector is not inserted inside an incubator, for example.
  8. Connect the micro-USB connector of the power supply to the service port of the data logger, and connect the power supply to a wall socket.
  9. Move the power switch to the On position.
  10. Look at the display and wait for the data logger to start up. The word NEW is shown for channels where a new probe has been connected. Note that the CO2 probe is always connected on channel 3.

    CO2 measurement shows dashes "- - -" while waiting for the CO2 probe to warm up. If dashes are not replaced by measurement readings within 30 seconds, check that the probe(s) and probe splitter are properly connected. It is possible to disconnect the probe splitter accidentally by pulling it with the battery cover open.

  11. Check that:

    • Battery indicator shows full batteries .

    • There are no error codes shown. If there are, see Error codes.
  12. Close the battery cover of the data logger. Push the latch down until you hear a click. If the cover does not close easily, push the probe splitter in and try again.

Once the data logger has been set up in CO2 probe mode, it requires a factory reset to allow it to be set up for non-CO2 operation. For the factory reset procedure, see RFL100 User Guide (M211861EN).
