Vaisala WXT530 Series User Manual

Averaging Time [A]
The a
veraging time in seconds, resolution 0.5 s. You can set a short averaging time (0.5 s) to
reduce the Pt1000 sensor self-heating. The message interval defines how often the
measuremen
t starts. The measurement is performed every 0.5 s for averaging time.
The range: 0.5 … 3600
Parameter Selection [aIU,R= (bit 1 and bit 9)]
The bits 7 and 14 enable normal and composite message for Aux rain accumulation. You can
select the parameters with the aIU command.
8.1.6.10 Parameter Order for SDI-12 Mode
The parameter order for SDI-12 mode is:
Analog in (M4): Tr Ra Sl Rt Sr
8.1.7 Analog Output
You can change the analog output type and scaling of WXT532.
WX
T532 provides the following analog outputs:
• AOUT1 for wind speed data
• AOUT2 for wind direction data
The analog output value is updated based on aWU,I= settings. Wind measurement uses
aWU settings, such as Averaging Time.
