d- Unit responds in an identical manner as the c command but does not clear the system
memory
E or e- Unit responds with minimum and maximums along with date and time of
occurrence. This uses the same buffer as the c and d command.
M- Unit responds with all term minimums and maximums with the date and time of their
occurrence, then clears.
m- Unit responds in an identical manner as with the M command but does not clear the
system memory.

The system has two completely separate memory buffers (C and M commands). C is
cleared every midnight. M is only cleared by pressing the clear and min buttons on the
display or sending an upper case M via a computer.
R- Unit responds with current conditions. The rainfall rate is present rather than the term
rain. (Note: in 30.04R the “R” denotes rising pressure)

r- Unit responds with current conditions. The term rain is present rather than the
rainfall rate. (Note: in 30.04F the “F” denotes falling pressure, a “S” character
denotes steady pressure.)

K- Unit responds with current calculated values for dew point, Windchill and heat
index.
Q- Unit response with hi resolution time, wind, temperature and pressure (in hi-res
models only).

The following commands respond if the WRL has logged data in memory.
T- Data logger top, moves pointer to the top of the data records, then sends data
N- Data logger next, moves pointer to the next data record, then sends data.
A- Data logger again, sends same data again.
P- Data logger previous, moves pointer to the previous data record, then sends
data.
B- Data logger bottom, moves pointer to the bottom of the data records.
