20.6.7 Message Verifikation
The command verification aV! is used to evaluate status information of the device. The device
responds with
a0004<CR<LF>
to the request, i.e. 4 values are available in the buffers.
The first 2 “measurement values”, transmitted in buffer ‘0’ contain the status information of the
measurement channels.
The status data of the channels are arranged into “fake” measurement values, each digit
representing on status value. The coding of the status is listed below. Generally each sensor
has to status values, one for the current measurement value, and one for the value buffer, which
is used for averaging and the evaluation of minimum and maximum.
The last two values, transmitted in buffer ‘1’, show the heating temperatures of the upper and
the lower heating of the wind sensor.
