Verify Access Password
When configuring a LogTag for its next use, if the user enables the " Configure requires a
password on page 26" option and/or changes the password to restrict access to the
LogTag, then the user is required to verify the password to be defined before it will be
stored in the LogTag. The window that will appear to verify the password will be similar to
the following picture.
Once a password has been stored in the LogTag, further access to it can only be achieved
by providing the correct password. Therefore, if a password is forgotten further access to
the LogTag will not be possible. Passwords are case sensitive and therefore the
passwords "Bob" and "bob", for example, are different.
Pre-start data collection
The LogTags support a feature called "pre-start logging", which can be selected during
configuration.
When pre-start logging is enabled the LogTag will automatically start logging as soon as
configuration is completed. It will record at the same sampling interval as defined in the
configuration and will continue to record until the user starts the LogTag by pressing the
START MARK button on the LogTag. Once the LogTag has been started, it will record as
per the configuration settings. While the LogTag is recording pre-start readings the Alert
LED on the LogTag will not activate if an alert condition is detected.
Pre-start logging is useful as a fail-safe recording setting so if the LogTag is not started at
the appropriate time, the readings will still be available to view later.
When the readings are retrieved from the LogTag, any pre-start readings will be identified
as pre-start readings so the user can quickly identify the readings recorded before and
after the LogTag was started.
All LogTags have a finite amount of memory to store the readings it records. Therefore,
while the LogTag is recording pre-start readings the LogTag will operate in its 'continuous
