Starting the Solinst Datalogger
There are two ways to start logging: Start Now or by programming a Future Start time.
To start logging immediately, do not click the Future Start box and click, . It should say Start Now below the icon to indicate an immediate start.
Figure 5-12 Starting the Datalogger Immediately
Before starting a Levelogger 5 Series datalogger, a pop-up window will indicate how much memory is available. Selecting "Yes" ignores the message and starts the datalogger immediately with the remaining available memory. Selecting "No" gives you the chance to access the Data Control tab to download and/or delete data files using the "Download and Delete Files" option, to free-up memory (see Section 7).
Figure 5-13 Remaining Memory Warning
When using an Edge or Gold Series datalogger, remember to download any data on the datalogger before starting a new session. When starting a new logging session, any data from previous recording sessions will be erased.
After selecting "Yes" any changed settings will automatically be applied to the datalogger, and it will start logging. Datalogger Status will change from Stopped to Started.
If a setting has been changed, it will be highlighted in yellow as a reminder before the datalogger is started. If a setting has been entered incorrectly, it will be highlighted in red. Changed settings are applied to the datalogger automatically when the Start icon is selected.
After the 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 datalogger will start logging and the Status will change from Future Start to Started.
Figure 5-14 Future Start Setting
Retrieve the Levelogger settings in order to refresh the status (i.e. when the status changes from Future Start to Started).
Using a Future Start to synchronize all of your Loggers to start at the same time is recommended when deploying a Barologger to compensate a number of Leveloggers.
Stopping the Levelogger Datalogger
There are two ways to stop logging: Stop Now or at a programmed Future Stop time.
To stop the Levelogger datalogger immediately when it is logging, click , (it should say Stop Now below the icon).
Figure 5-15 Stopping the Datalogger Immediately
The Levelogger can be stopped at any time before it reaches the maximum reading capacity.
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.
If you have set a Future Stop time, but wish to stop the datalogger immediately, uncheck the Future Stop 'At' box, and the Stop icon should say Stop Now. Click the icon to stop logging.
Figure 5-16 Future Stop Setting
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. 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 5 and Levelogger Edge units record in Slate mode if Event or Schedule logging, but in standard Linear mode they can be set to Slate or to Continuous logging.
