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 CO
2
probe is always
connected on channel 3.
CO
2
measurement shows dashes "- - -" while waiting for the CO
2
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 (page 23).
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 CO
2
probe mode, it requires a factory
reset to allow it to be set up for non-CO
2
operation. For the factory reset
procedure, see RFL100 User Guide (M211861EN).
