64 Using Telemetry OVEN TRACKER XL2
• After completing your selections in the Reset dialog, leave the
communications lead attached to the logger and PC.
• The Select Process dialog then appears in order that you may choose a
process file to apply to the results. If the process file and its components
have been given names, these are shown when the process file is selected in
the list. Click ‘No Process’ if you do not want to apply a process file.
(A process file allows you to see the temperature profile in relation to the
oven zones as the profile appears on screen during the run. 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’.)
• There will normally be no need to use a thermal barrier to protect the
logger.
WARNING
All the thermocouples which are to be used must be plugged into the Transducer
Interface before the Transducer Interface is attached to the MemoryPaq. If any
thermocouples are plugged in after the MemoryPaq has been attached, data
from those thermocouples will be ignored.
Similarly, if a Dual Interface Block is fitted, either one or two Transducer
Interfaces (each with any number of thermocouples connected) may be attached
to it – but, if two Transducer Interfaces are used, both must be attached to the
Dual Interface Block before the MemoryPaq is plugged into it. If the second
Transducer Interface is attached after the MemoryPaq is connected, data from
thermocouples plugged into the second Transducer Interface will be ignored.
You may specify that a password is required when an attempt is made to
close Insight while a real-time telemetry run is in progress: select Tools >
Options > General from the menu bar.
If the logger’s memory becomes full during hard-wired data-collection, the
logger will continue gathering data, but excess data will be passed to the PC
and not stored by the logger. When the profile run is complete, the full data
can then be saved as a paqfile within Insight (see below). When the logger’s
memory is filled, the MemoryPaq display flashes ‘88’.
Real-time Display During the Run
After the first few data packets have been received, the data starts to be
displayed in the Graph and Analysis Windows, scrolling in real time as new data
is received. You may change the way the data is displayed with the Axes tab of
the Graph Options dialog (from the right-click menu, or from the main menu
select View > Graph Options): under Telemetry, specify how much of the
recently received data is displayed, and whether you wish to see only a certain
temperature (y-axis) range, centered on a the latest data.
