If a setting has been changed, it will be highlighted in yellow as a reminder before the AquaVent is started.
If a setting has been entered incorrectly, it will be highlighted in red.
Changed settings are applied to the AquaVent automatically when the Start icon is selected.
Starting the AquaVent
There are two ways to start logging: Start Now or by programming a Future Start time.
When starting a new logging session, any data from the previous recording session will be erased (see Section 5 for downloading data).
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 AquaVent, and it will start logging. Datalogger Status will change from Stopped to Started.
Remember to download any data from the AquaVent before starting a new session. When starting a new logging session, any data from previous recording sessions will be erased.
After the AquaVent 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.
Figure 4-10 Starting the AquaVent Immediately
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 AquaVent will start logging and the Status will change from Future Start to Started.
Figure 4-11 Future Start Setting
Retrieve the AquaVent settings in order to refresh the status (i.e. when the status changes from Future Start to Started).
Stopping the AquaVent
There are two ways to stop logging: Stop Now or at a programmed Future Stop time for the AquaVent.
To stop the AquaVent immediately when it is logging, click , (it should say Stop Now below the icon).
The AquaVent 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.
Figure 4-12 Stopping the AquaVent immediately
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.
To program a Future Stop time for your AquaVent, check Future Stop 'At' and fill in the desired stop time. The Future Stop time will be applied to the AquaVent once is selected for an immediate or future start.
You can also program a Future Stop time after you have started the AquaVent, 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.
Figure 4-13 Future Stop Setting
It is critical to note that when the AquaVent logs data in Slate mode, it means it will record data until stopped or their memory is full. When the memory fills, the AquaVent 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 AquaVent will stop recording. The AquaVent records in Slate mode if Event, Schedule, or Compressed logging. Standard Linear mode, however, can be set to Slate or to Continuous logging.
