Latch of the battery cover.
  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. If a probe is not already connected to the data logger, connect it now:
    • To connect a probe directly to the data logger, first align the orientation mark on the probe with the line above the probe connector. Then push the probe in all the way, do not rotate.
    • To connect a probe using an extension cable, use an accessory cable that has been designed for RFL100. Insert the cable connector in the same way as a probe, and then connect the probe to the cable. Note that HMP110 and HMP110T probes must always be connected using a cable as they do not mechanically lock into the data logger when the battery cover is closed.
  5. Move the power switch to the On position.
  6. 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 (or extension cable) in and try again.
  7. Look at the display and wait for the data logger to start up. Then verify the status:
    • Data logger shows the word NEW on each affected channel when it detects that a probe has been changed 1. The text is shown for a few seconds, after which the display shows the measurement reading(s).

    • If dashes "- - -" are shown instead of measurement readings, check that the probe is properly connected. It is possible to disconnect the probe or cable by pulling it with the battery cover open.
    • Battery indicator should show full batteries .

    • There should be no error codes shown. If there are, see Error codes.
