Setting Action
Logging Tap Logging Intervals and select how often the
Intervals logger will record data. When selecting a logging
interval, keep in mind that data offload time is
proportional to the amount of data logged. The
faster the logging interval, the more data that will
need to be offloaded and the longer it will take.
Multi-Rate Logging
You can set a total of 8 logging intervals. After
tapping Logging Intervals and entering a rate for
Interval 1, tap Add to set up additional logging
intervals. For each interval, enter the rate and
select the number of samples that will be
recorded for the selected rate. Tap Save.
Start Tap Start Logging and choose one of the following:
Logging
• Now. Logging will begin immediately after the
Options
configuration settings are saved to the logger.
• On Next Logging Interval. Logging will begin at
the next even interval as determined by the
selected logging interval.
• On Date/Time. Logging will begin at a date and
time you specify.
Tap Save.
Stop Tap Stop Logging and choose a memory option:
Logging
• When Memory Fills. The logger will continue

recording data until the memory is full.
• Never (Wrap When Full). The logger will
continue recording data indefinitely, with
newest data overwriting the oldest. This option
is not available if the Logging Mode is set to
Burst (see Burst Logging) or if you set up
multiple logging intervals.
Select one of the following time options for when
to stop logging:
• Never. Select this if you do not want the logger
to stop at any predetermined time frame.
• On Date/Time. Select this if you want the logger
to stop logging on a specific date and time.
Select the date and time.
• After. Select this if you want to control how
long the logger should continue logging once it
starts. Choose the amount of time you want the
logger to log data. For example, select 30 days if
you want the logger to log data for 30 days after
logging begins.
Tap Save.
Logging Tap Logging Mode. Choose the logging mode (note

• Fixed Logging. Select Normal to record the
current reading for each enabled sensor at each
logging interval. Note that this is also the mode
you need to select for multi-rate logging. You
must select Normal if you want to log water
level and barometric pressure data. If you
deselect Normal, the logger will only record
statistics series for the enabled series. It will not
be able to calculate water level or barometric
pressure.
• Statistics. Select any statistics you want to
record (maximum, minimum, average, and

configuration settings The logger will begin logging data
based on the settings you selected. After logging begins,
you can read out the logger at any time (see Reading Out
the Logger for details). You can update the reference water
level or water density during the deployment if necessary
(see Updating the Reference Water Level and Water
Density).
Notes:
• When the logger is stopped, the water level reading
shown while connected to the logger does not reflect any
reference water level and water density values you have
entered (it reverts to a reference water level of zero and
a water density of "Fresh Water adjusted for
Temperature"). Once logging begins, the readings shown
in the app will be based on the reference water level and
water density you entered.
• If the logger is logging and you start a new deployment,
the logger will take a current water level reading and use
that as the default reference reading for the new
deployment.
• These are the options available when the logger is
connected to the app:
