3. After clicking OK, the logger is reset and a message box confirms the
sample interval and trigger mode you have set.
4. Disconnect the communications lead from the logger; the logger's status
LEDs briefly flash red and green alternately to confirm logger reset. Replace
the dust-cap on the communications port.
Installing the Logger in the Thermal Barrier
For correct selection of a suitable barrier, see p. 22.
Allow for the time taken to recover the Tracker system after the test when
calculating the thermal performance requirement for the thermal barrier.
Before proceeding, ensure the thermal barrier has cooled sufficiently
1. Plug the thermocouples into the logger's numbered sockets.
If any socket – including the humidity-sensor socket – is unused, insert a
blanking plug (see p. 19) to guarantee waterproofing.
If you are using a process file, ensure that the probe/socket numbers on the
logger correspond to those used to define probe numbers and locations in
that file (see the Insight software for an introduction to process files: press
function key F1, or select Help > Contents from the menu bar, and click the
section 'Process Files: Oven, Recipe, Product'). Ensure that each probe
connector is pushed home completely and all that connectors protrude the
same amount from the face of the logger. For use of a submersible barrier, see
below.
2. Ensure the barrier's mating surfaces are clean and undamaged. A good seal
between thermal barrier and thermocouple cables is essential if the data
logger is to be protected. Put the logger in place in the barrier – within the
heatsink(s) if used – laying the thermocouple cables across the sealing
material to exit the barrier at the cutout, and ensuring that they lay side by
side and not crossing each other. For use of a submersible barrier, see below.
3. If the trigger mode is Start Button, press and hold the start button for about
1 second until the green LED starts to flash at the sample interval.
4. Close the lid ensuring a good seal around the thermocouple cables.
5. Place logger/barrier onto conveyor belt or rack; conveyor should be stopped
first if possible.
6. Insert probes into product or oven at required locations (see p. 37).
