(

When shipped from the factory, the unit is in ‘shipping mode’ (deactivated; not logging
or calling in). This mode is suitable for shipping or long-term storage. To use the logger,
it must first be
activated
.
The process for doing this depends upon the logger setting for logging re-activation.
Various setting options are available (specified time, upon connection of an external
battery, upon the activation of a magnetic switch
, ‘immediately’
).
M
ost loggers are set to start ‘immediately’ upon having
their settings read by IDT and
then saved back to the unit.
Once activated, the logger will initially go into the state of
‘
Waiting
’
(for a short time).
Then it will
enter a status of ‘recording’, where it is executing its repetitive logging
functions.
The method depends on which version of IDT is being used:
•
For IDT (PC), the user can do this manually (even if no program changes are
required). (Refer to the IDT user-guide for the steps required to read the logger
program and then to save it back to the unit using the ‘Setup Device’ button).
•
For the IDT app, the user can also do this manually via a Start Device’ button.
In addition, the app will check for potential issues whenever the user makes a
controlled disconnection of the logger from the app, including a check for a
logger that is not yet activated / recording.
