[S]
=
Hail units:
M
= metric (accumulated hailfall in hits/cm
2
, Hail
event duration in s, Hail intensity in hits/cm
2
h)
I
= imperial (the corresponding parameters in units
hits/in
2
, s, hits/in
2
h), H = hits (hits, s, hits/h)
Changing the unit resets the precipitation counter.
[M]
=
Auto-send mode: R = precipitation on/off, C =
tipping bucket, T = time based
R
= precipitation on/off: The transmitter sends a
precipitation message 10 seconds after the first
recognition of precipitation. Rain duration Rd
increases in 10 s steps. Precipitation has ended when
Ri = 0. This mode is used for indication of the start
and the end of the precipitation.
C
= tipping bucket: The transmitter sends a
precipitation message at each unit increment (0.1
mm/0.01 in). This simulates conventional tipping
bucket method.
T
= time based: Transmitter sends a precipitation
message in the intervals defined in the
[I]
field.
Do not use the auto-send mode tipping bucket in
polled protocols as it decreases the resolution of the
output (quantized to tipping bucket tips).
[Z]
=
Counter reset: M = manual, A = automatic, L=limit
Y = immediate
M
= manual reset mode: The counter is reset with
A
= automatic reset mode: The counts are reset after
each precipitation message whether in automatic
mode or when polled.
L
= overflow reset mode. The rain counter or hail
counter is reset, when it reaches the predefined limit.
The overflow limits (x, y) are defined with the
commands aRU,X=x for rain counter and aRU,Y=y
for hail counter.
Y
= immediate reset: The counts are reset
immediately after receiving the command.
