File Information
This section shows general information about the PDF file, such as generation time, date
and time formats used in the chart and the data list as well as the file name, which is
compiled from information about the data it contains:
LogTag_[serial_number]_[trip number]_[file creation date]_file creation time]_[OK or ALM].pdf
Other files that may be generated have the extensions *.csv and *.ltd.
Logger Information and Configuration
This section shows general information such as serial number, model number, trip
number, battery status and description. It shows how the logger was started, if a start

Recorded Data Overview
This section shows at what time the logger started to record data, when it finished, how
many readings were recorded and how long that took.
Logger Statistics Overview
This section gives a brief overview of the temperature data collected during the trip. It
shows minimum and maximum values, when these occurred and also shows average,
standard deviation and MKT values.
Upper and Lower Alarm Information
These two sections summarize the alarm trigger conditions and occurrences during the
trip:
l
Alarm threshold temperature value
l
Any delay value for consecutive or accumulative alarms
l
The total time above or below a threshold
l
How often an alarm occurred
l
Whether or not an alarm was generated for this alarm trigger
You may see up to three alarms for each direction, depending on the logger's
configuration.

is presented.
Markers
On the chart, special symbols will mark the readings at which certain events took place:
