Reset Mode [M]
[M] defines the reset mode.
The initial tip counter overflows if it reaches 65536 and it starts from 0.
If the tipping bucket resolution is 0.2 mm per tip, the gain is 0.2, and the
maximum rain amount before overflow is 65536 * 0.2 = 13107 mm.
Limit [L]
[L] defines the reset limit. The rain counter resets when it reaches this
value. The unit is the same as in gain [G].
The range: 0.000 000 001 ... 1 000 000
Parameter Selection [aIU,R = bit 2 and bit 10]
Bits 7 and 14 enable normal and composite message for aux rain
accumulation. You can select the parameter with the
aIU
command.
The maximum value for the rain counter is 65535 * gain.
Solar Radiation Sensor Settings
[aIB]
Gain [G]
[G] defines the volts / user unit, for example, µV/W/m
2
. WXT reports
the voltage at solar radiation input multiplied with gain [G].
For example, if the solar radiation sensor has sensitivity 5 µV/W/m
2
and
you set the gain [G] to 1/ µV = 200 000, the solar radiation value
reported by WXT is in W/m
2
. WXT reports the value always with six
decimals.
