Precipitation Sums
PWD32 has no internal clock for automatic resetting of the sum data at
certain times. This can be done by the host with the following command:
;PW id C
C
R
where
;
=
ESC (ASCII character 1B hex).
C
R
=
Carriage Return (13 hex.)
PWD32 then responds to the accepted command with the ASCII
character ^F (ACK; 06 hex).
The host computer can also maintain its own sum calculated from the
continuous PWD32 data. This may be safer, if the PWD32 power breaks
often and resets the sums before the scheduled time. The water sum is
automatically reset, when it reaches 99.99 mm and the snow sum at 999
mm.
