them to the measuring point. However, attachment is improved by using self-
adhesive aluminum tape and deforming it to fit closely around the thermocouple
tip; high-temperature tape placed over this will hold it in place during the
profile run.
Restraining the Cable
The thermocouple cables must be routed from their points of attachment to
the rear of the PCB to enable the data logger to follow the PCB through
the oven.
1. Route the thermocouples from their points of attachment to the rear of
the PCB.
2. Attach the thermocouple cables to the PCB at intervals, using high-
temperature tape.
Preparing the Logger
• If the data logger is being connected to a PC for the first time, it is
necessary to enable communication between them.
• The logger must also be reset before a profile run – using Insight software –
to establish its data-collection parameters (not necessary if parameters are
to be unchanged from the previous run).
• If there is any doubt that the logger’s battery charge may be inadequate
for the profile run, this must also be checked by using the reset procedure.
For the procedures involved, see your dedicated logger manual or
the Insight Help system.
Note that, since its last use, the logger must have cooled below 35°C
(comfortable to hold without gloves).
