9.3.1
General Information Field
General information on the top of the screen informs the model, serial number, logger current date/time, PC date/time, firmware version (logger
model version), memory capacity and used memory. This information is displayed in the upper part of the LogChart-II configuration screen.
The time is constantly updated in this screen, provided that the logger and the PC are communicating
9.3.2
Acquisition Field
•
Period
: It determines the interval between readings in the hh:mm:ss format. New data is stored in the logger memory after each time
interval. In the
Instantaneous
reading mode, the value of the interval between acquisitions is the same as the time interval between
measurements. For
Average
,
Minimum
and
Maximum
readings, the logger executes 10 readings within this interval.
•
External Battery Switch time
: Defines the time when the logger turns on the power supply, before proceeding with any reading. This
time is limited to 10 seconds and must be less than half of the interval between readings.
•
Estimated time
: It informs the estimated time for the accomplishment of programmed readings based on the logging “Interval” and on
the number of programmed readings.
•
Daily Repetition
: Allows loggings to be repeated every day, for example, recording data from 8 AM to 5 PM day after day. The start
and stop times are defined in the fields “Start time” and “Stop time.”
9.3.3
Start Logging Field
•
Immediately
: The logger starts logging as soon as the configuration is applied. Not valid when the option ‘Daily Repetition’ is
selected.
•
Day / Hour
: Logging starts at a defined date and time. The date defined is used for the Daily Repetitions option as well.
•
With Start Button:
Starts and stops logging by pressing the Star button for two seconds.
•
Digital Input
: Starts readings when the digital input is activated (closed) and stops readings when the digital input is deactivated
(open).
9.3.4
Stop Loggings
•
At Full Memory
: Loggings can be stored up to the full memory capacity is reached.
•
Wrap around
: Logging never stops. The LogBox-AA will keep on recording the readings and when the memory is full it will overwrite
the oldest record in a circular or wrap around manner.
•
After a defined number of readings
: The logger will stop logging after the number of readings here defined is reached. Not valid
when the option ‘Daily Repetition’ is selected
•
Day / Hour
: The LogBox-AA will stop logging at the user-defined date and time. Not valid when the option ‘Daily Repetition’ is
selected.
