5.3.3 Replacing probes when two probes are connectedYou can replace one or both of the probes by following the procedure below. Onlytemperature probes are supported in two probe mode.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. Replace the first probe:a. Loosen the locking ring of the connector at the end of the probe cable or probesplitter, and pull the old probe away from the connector.b. Connect the new probe and tighten the locking ring.c. Remove the numbering label from the old probe and apply it to the new probe.5. Move the power switch to the On position.6. Look at the display and wait for the data logger to start up. Data logger shows the wordNEW on the channel that was affected by the probe change for a few seconds, afterwhich it is replaced by the temperature reading. Verify that the display showsmeasurement readings instead of dashes or error codes.7. To replace the second probe, repeat the steps starting from step 3.8. Optional: Press the info button on the data logger (under the silicone plug, next to theservice port) and verify the channel assignment of the probes using the Info mode.9. Close the battery cover of the data logger. Push the latch down until you hear a click. Ifthe cover does not close easily, push the probe (or extension cable) in and try again.10. Insert the data logger back in the mounting bracket.5.3.4 Changing from one probe to two probesYou can change to two probe use by performing the two probe setup. See Setup with twotemperature probes (page 23).5.3.5 Changing from two probes to one probe1. Remove the data logger from the mounting bracket.2. If any cable is connected to the service port of the data logger, disconnect it.3. Open the battery cover of the data logger.4. Move the power switch to the Off position.5. Perform the factory reset procedure to the data logger. See Performing a factory reset(page 59).6. Move the power switch to the Off position.7.
