Clear Rainfall Log: Totally erases the rainfall log

The dump river command (DURV) unloads the historicalriver record from the start of the record to
the most recent event stored. On completion of successfuldata retrieval, the memory remains intact
until cleared by the clear river log user command (CLRV). When the memory becomes full, the
logger stops logging and tacks a "Mem Full" message onto the end of an event message. The river
log may be dumped in ascii or hex format. The ascii format is readable (as shown in section 4.2.2.)
and the hex format must be interpreted by separate software which converts it to ascii format. The
hex format has the advantage that the data is still compressed and will download faster. The dump
command also allows for searching through the log and starting at a specific location instead of
dumping the complete log. See the DUR On-line help for syntax and see section 4.2.2. for an
example of the dumped river record.

Logging to memory may be turned on and off using the log flag. This is used when a site needs to
be tested but the existing log should not be disturbed. As the flag is turned on or off, an event is
stored in the rain and river log that indicates the time of "Logging Disabled" and "Logging Enabled"
for future reference. See the river log example in section 4.2.2.

Logging On/Off: En or dis logging to memory. Used when testing
a station, events still reported through serial port

Anew command, MemoryWrap (MW), enables or disables the wrapping ofmemory. Whenmemory
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 is equivalent to approximately 8100 rain events, or 8100
quadrature river events or 4050 4-20mA river events.) In this mode memorynever becomes full, and
