Logger Communications Problems
Communications lead not fully inserted – Check correct sockets are
being used.
Damaged communications lead or connectors – Check for breaks
and other damage; replace the lead.
Batteries not charged – Recharge the batteries, ensuring the charging
LEDs are illuminated (see p. 12).
To minimize communications problems:
Connect the lead first to the PC and then to the logger.
Always use the same USB port – the one which was first used to set
up communications (p. 21).

inappropriate use or handling can produce erroneous readings. If you suspect
that invalid data may have been introduced into your temperature profile
(paqfile), select the View Data tab in the Insight software's Analysis Window to
view the raw data as downloaded from the logger. The various types of invalid
data which may be contained in a paqfile are shown in the analysis grid as
