Analog Output
Analog outputs are either enabled or disabled, and the output
settings are preconfigured at the factory according to your order.
In analog output operation WMT700 takes measurements
according to the configured averaging time and synthesizes the
analog outputs of wind speed and wind direction with an update
interval of 0.25 seconds.
You can change the analog output type and scaling of WMT700
according to your needs. You may also need to disable the analog
output functionality to save power. For instructions, see
Configuration Parameters on page 118.
WMT700 provides the following analog outputs:
- AOUT1 for wind speed data
- AOUT2 for wind direction data
NOTE To emulate the WS425 analog output, choose voltage output, frequency
output, and potentiometer. For more detailed instructions, see section
Operating WMT700 in WS425 Analog Output Mode on page 139.
For information on wiring, see section Wiring on page 77.
