PWD22/52 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
E C
R
C
where
E
C
C
R
PWD22/52 then responds to the accepted command with the ASCII
A
character < (06 hex).
K
The host computer can also maintain its own sum calculated from the
continuous PWD22/52 data. This may be safer, if the PWD22/52 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.
