[X] = Rain accumulation limit : 100...65535.
Sets the rain accumulation counter resetting limit.
When the value exceeds the limit, the counter is reset
to zero. If the precipitation unit aRU,U=x is metric,
the limit corresponds the range between 1.00
…655.35 mm. If the precipitation unit is imperial,
the equivalent range varies between 0.100 … 65.535
in.
To enable this feature, set the counter reset to
aRU,Z=L (overflow reset mode).
[Y] = Hail accumulation limit : 100...65535.
Sets the hail accumulation counter resetting limit.
When the value exceeds the limit, the counter is reset
to zero.
If the hail unit aRU,S=x is metric, the limit
corresponds the range between 10.0 …6553.5 hits/
cm
2
. If the unit is imperial, the equivalent range
varies between 100 … 65535 hits/in
2
. If the unit is
hits, the limit matches directly to the amount of hits:
100…65535 hits.
To enable this feature, set the counter reset to
aRU,Z=L (overflow reset mode).

NOTE The autosend mode parameter is significant only in ASCII automatic
(+CRC) and NMEA 0183 automatic protocols.
NOTE Changing the counter reset mode or precipitation/surface hits units
also resets precipitation counter and intensity parameters.
The field [Z] defines how the counters are reset. Use "L" to enable the
rain overflow reset mode. Now the rain accumulation limit feature (X
and Y) becomes particularly useful for systems using an analog
interface adapter. Thus, the dataloggers have no serial interface that
would enable them to reset the rain counters.
