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. The analog output signal type and range depend on the configured settings.

Normally, analog output is enabled and the output settings are preconfigured at the factory according to your order. WMT700 can be operated using these settings directly after the installation. However, the analog output settings of WMT700 can be changed or the analog output functionality can be disabled at any time to save power over the serial interface.

When operating WMT700 in a system configured for WS425, you must configure the analog output settings according to the following table using the S command.
