Memory Map: Selecting [YES] for this item enables a snapshot display of current memory usage. In this
display, the asterisk indicates a used block, a space indicates a free block, while a dash character indi-
cates unused filler.
Data Memory Left: This view only menu cell
shows the minimum remaining number of char-
acters available for Datalogger and site storage.
When the Datalogger is enabled for circular mode,
the meter alocates all of memory except for two
conventional empty sites worth for datalogger use.
4.12.4 THE MEMORY CONTROL MENU
Memory Control is a reference menu that shows the amount of bytes of data memory left. The data
memory capacity depends on the number and complexity of the site setups stored in memory and
the size of the current datalogger file. Capacity is also affected by the RAM option with which your
flowmeter is equipped with - either 900k expanded or 170k standard RAM.
Press the <Right Arrow> to view the amount of memory bytes available.
All active channels in the Channel Setup menu must be disabled. To disable active channels,
select the [Channel Enable] menu cell and then [No].
In the Datalogger Control menu, select [Circular Memory].
Press to access the [Circular Memory] option list.
Move the cursor to [Yes] by pressing
To store selection press
Lastly, re-enable the channels that you disabled earlier to begin logging.
EST LOG TIME LEFT
Est Log Time Left is a “view-only” menu cell that shows an estimate of the amount of Datalogger time
remaining in hours and minutes. This menu cell becomes active after you enable datalogging. Selecting
Circular Memory and/or event-based datalogging (see Datalogger Setup), blanks the field [Est Log Time
Left] and is based on the log interval and data selections made in the Datalogger Setup. For Single-
Channel flowmeters, this time is an estimated minimum since data compression is employed for im-
proved storage efficiency.
Clear Datalogger
If you use the Datalogger in its default mode, eventually you will use all the memory available for Data-
logger storage. When this occurs, you will not be able to log more data until you free up the memory. The
Clear Datalogger command erases ALL stored Datalogger data. Therefore, you should evaluate the
currently stored data, and print any valuable information before using this command. Note: Saved Sites
also consume datalogger RAM.
