format, as shown in section 4.2.1.
DUALL<CR>
Dump the complete log of all parameters.
The DUALL command has all the same search syntax as the DUR command.
The “Dump River log” (
DURV
) command, unloads the 4-20mA river level log from the start
of the record to the most recent event stored. On completion of successful data retrieval, the
memory remains intact until cleared by the clear log command (
CLRV
) – please note that the
CLRV command also clears all logged data, rain, river, battery and temperature!! The log is
dumped in ascii format, as shown in section 4.2.1.
DURV<CR>
Dump
the
complete 4-20mA River log record.
The DURV command has all the same search syntax ad the DUR command.
The “Memory Wrap” (
MW
) command, enables or disables the wrapping of memory. When
memory wrap is on, and the historical log becomes full, then the first data stored will be
erased one block at a time. (A block of Flash memory holds approximately 400 events, and
there are 1023 blocks available.) In this mode memory never becomes full, and the most
recent data is always available. It is advisable that when changing the state of the Memory
Wrap flag, the existing logged data be erased so that logging can start afresh.
MW<CR>
Display the present state of the memory wrap flag
MW=ON<CR>
Turn memory wrap on.
MW=OFF<CR>
Turn memory wrap off.
NOTE:
It is best to clear all of memory (using CLR) when changing this flag.
The “Clear Record” (
CLR
) command erases the complete memory log of all history –
note
that this command erases the Rain, River, Battery Voltage and Temperature logs. A question
will appear to remind the user that all data will be erased – answer y or Y to delete the log
and any other key to abort.
CLR<CR>
Erase
complete
log
record.
