Lastly, re-enable the channels that you disabled earlier to begin logging.

4.4.4 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. Select- ing 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 improved storage efficiency.

4.4.5 CLEAR DATALOGGER

If you use the Datalogger in its default mode, eventually you will use all the memory available for Datalogger 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.

To clear Datalogger Data Memory:

To access the Clear Datalogger option list press

Move the cursor to [Yes] by pressing

To clear the memory press ENT

4.5THE 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 1010 is equipped with - either 900k expanded or 170k standard RAM.

Data Memory Left: This view only menu cell shows the minimum remaining number of characters avail- able for Datalogger and site storage. When the Data- logger is enabled for circular mode, the meter allo- cates all of memory except for two conventional empty sites worth for datalogger use.

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 indicates unused filler.

Defragment: Selecting YES for this item consolidates memory data blocks into contiguous storage; collapsing the filler regions. You may be able to use an additional block for site or datalogger storage as a result. Use this command if you seem to be out of memory even though the Data Memory Left item indicates free capacity.
