5.8 Starting and Stopping the
Levelogger Datalogger
There are two ways to start logging: Start Now or by programming a Future Start time.
To start logging immediately, do not fill in a Future Start time and click,  .
It should say Start Now below the icon to indicate an immediate start. Any changed settings will automatically be applied to the Levelogger datalogger, and it will start logging. Levelogger Datalogger Status will change from Stopped to Started.
After the Levelogger datalogger is started, and begins collecting readings, the Start icon will be greyed out, and only the Stop icon and Future Stop settings will be active.

Check Future Start 'At' to set logging to start at a later date and/or time. This Start mode is referred to as Future Start in the Status field. Click to apply the Future Start time and any changes to the datalogger settings.
When the Future Start time is reached, the Levelogger datalogger will start logging and the Status will change from Future Start to Started.

Stopping the Levelogger Datalogger
There are two ways to stop logging: Stop Now or at a programmed Future Stop time for the Levelogger Edge and Barologger Edge.
To stop the Levelogger datalogger immediately when it is logging, click  , (it should say Stop Now below the icon).
The Levelogger can be stopped at any time before it reaches the maximum reading capacity. Starting again begins a new recording session and clears previously stored data readings.

To program a Future Stop time for your datalogger, check Future Stop 'At' and fill in the desired stop time. The Future Stop time will be applied to the datalogger once is selected for an immediate or future start.
You can also program a Future Stop time after you have started the datalogger, by checking Future Stop 'At' and filling in the desired stop time. Select to apply the Future Stop time (it should say Future Stop below the icon). The Stop Time should be shown in the Datalogger Status section.

It is critical to note that when Leveloggers log data in Slate mode, it means they will record data until stopped or their memory is full. When the memory fills, the datalogger will stop recording. For this reason, it is important to determine, based on your start time and sampling rate, the date and time at which the memory will be full and the datalogger will stop recording. Levelogger Edge units record in Slate mode if Event, Schedule, or Compressed logging, but in standard Linear mode they can be set to Slate or to Continuous logging.
