7.1.3 Status Fields
There are a number of different status codes, which give the user information about various aspects
of the anemometer. Each of these codes has an address field followed by a data field. The address
field defines which particular aspect of the anemometer the following data field refers to.
The address fields are defined as follows:
StaA - Status Address
Address Function
00 Error
codes
01 Anemometer configuration
02 Data output configuration 1
03 Data output configuration 2
04 Error code history
05 Transducer gain levels
06 Anemometer Type
07 Inclinometer X axis MSB
08 Inclinometer X axis LSB
09 Inclinometer Y axis MSB
10 Inclinometer Y axis LSB
In normal operation the anemometer output cycles through the status codes 01 - 06 at each output
sample. If the anemometer detects an error then the status code 00 is displayed instead of the next
cyclic status code. When the error is cleared, the status codes will continue to cycle from where they
were interrupted.
If the error is caused by a transducer pair failure then the error code is displayed until the failure is
rectified.
If the error is caused by a memory or PRT failure, then after 16 consecutive failed readings, the error
condition is reduced to the error code history status and the error cleared.
