  1. Remove the data logger from the mounting bracket.
  2. Open the battery cover of the data logger.
  3. Move the power switch to the Off position.
  4. To replace a fixed probe (directly connected to RFL100 without a cable):
    1
    Orientation mark on data logger
    2
    Orientation mark on probe
    1. Grip the old probe from above the filter and hold the data logger with your other hand. Pull the probe straight out of the data logger. Do not rotate the probe.
    2. Align the orientation mark on the new probe with the line above the probe connector. Push the probe straight in all the way, do not rotate.
  5. To replace a cabled probe:
    1
    Locking ring on probe cable or probe splitter
    1. Loosen the locking ring of the connector at the end of the probe cable, and pull the old probe away from the connector.
    2. Connect the new probe and tighten the locking ring.
  6. Move the power switch to the On position.
  7. Look at the display and wait for the data logger to start up.

    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). Verify that the display shows measurement readings instead of dashes or error codes.

  8. 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.
  9. Insert the data logger back in the mounting bracket.
