2.0 INTRODUCTION MODEL 85106 ULTRASONIC ANEMOMETER The YOUNG Ultrasonic Anemometer is a 2-axis, no-moving-parts wind sensor. It is ideal for general meteorological applications requiring accurate and reliable measurement. The sensor features wide operating range, compact size, easy installation and low power operation. Analog and digital signal outputs are available in several popular formats. The Ultrasonic Anemometer measures wind based on the transit time of ultrasonic pulses between four transducers.
.0 OPERATION The sensor wind speed threshold is preset to 0.25 m/s (0.6 mph). Wind below this level is displayed as zero. The wind direction display will show the last value that appeared when wind speed was above threshold. 3.3 5.1 WITH YOUNG MARINE WIND TRACKER DISPLAY The default serial output format is NMEA which is compatible with the Young Model 06206 Marine Wind Tracker display. The Marine Wind Tracker receives measurements in the form of ASCII data via an RS-485 serial connection.

If the prompt does not appear after receiving three ESC characters, re-check the wiring and communication program setup. If the sensor baud rate is unknown, try sending the ESC characters at each of the four available baud rates (1200, 4800, 9600, and 38400).

The default value is 10000 for a multiplier of 1.0000. This may be used to individually calibrate each sensor for improved accuracy. 6.4.8 SET08nnnnn SET WIND DIRECTION OFFSET 6.
Serial ASCII and ASCII POLLED formats report a STATUS CODE where non-zero values indicate insufficient samples or measurement error. SET14n determines how the STATUS CODE is handled in the voltage output. 7.6 SDI-12 STANDBY Serial Output Format: Output Delay: Damping Factor: Sample Count: 1 = None (ignore STATUS CODE) 2 = Set Vouts to 0V when STATUS is non-zero 3 = Set Vouts to 5V full scale when STATUS is non-zero 6.4.
