13. DATA LOG FILE
At regular intervals of either 15 minutes or 1 hour
(see Function 20), the charger will store information
into a data log file. Up to 384 records of information
are saved and can be examined later. When the file
is full, as new data comes in, the oldest data is
erased. For example, if 1 hour is selected for the
time interval, the charger will remember statistics for
16 days. Using the shorter time interval, only the
last 4 days of charge data will be saved.
information is useful in monitoring the activity of the
charger and the batteries. When an error occurs, it
is also written into the data log file, followed by a line
of charge data which specifies the time of the error.
A portable printer or terminal may be used to collect
the data. The format of the data dump is the same
as shown under item 11. If a printer is used, dump
the data log file by executing Function 21. To stop
the dump, press and hold the CLEAR button until

"888" appears on the display. If a terminal is used,
select the DUMP command. Pressing any key on
the terminal will stop the dump. When a terminal is
used, the data log file may be downloaded to the
terminal if it is set up to capture the data. The time it
takes to dump a full file is approximately 13 minutes
when the baud rate is set at 300. If the AC power is
disconnected or interrupted, the data log file may
contain random information.
